MB Sturgis Propane Fittings - 100473-20-MBS

  • Hoses
  • Pigtail Hoses
  • 1-1/2 Feet Long
  • 1/4 Inch - Male NPT
  • Type 1 - Female
  • MB Sturgis

Pigtail makes the connection from the propane tanks on your trailer to the propane regulator. Also used to connect tanks to a high-pressure regulator to carry gas to a 2-stage regulator. Check valve prevents hazardous backflow leakage.


Features:

  • Propane pigtail connects your propane cylinder to a regulator
    • Used for single or dual tank setups on the front of your travel trailer
    • Also used to connect a remote tank to a high-pressure regulator
  • Female Type 1 fitting connects to the valve on your propane cylinder
  • Male NPT connects to a propane regulator
  • Built-in bypass mode shuts gas off when flow reaches maximum capacity for safety
    • Thermal shut-off device turns off gas flow in extreme heat caused by open flame
    • Excess-flow safety device limits gas flow in the event of a severe leak
  • Durable thermoplastic hose and brass fittings approved for LP gas only
    • Rated for high pressure and high flow rate to handle unregulated propane
    • UL569 and ANSI Z21-81 certified
  • Made in the USA


Specs:

  • Temperature range: -40 F to 140 F
  • Hose dimensions: 20" long x 1/4" inner diameter
  • Hose fittings:
    • Female Type 1
    • 1/4" Male NPT
  • Maximum pressure rating: 350 psi
  • Maximum flow capacity: 450,000 Btu per hour
  • 1-Year limited warranty


This propane hose is ideal for travel trailers with a split-tank system. This kind of system features 1 cylinder on the driver's side and 1 cylinder on the passenger's side of your trailer. This hose connects the cylinder on the passenger's side to a high-pressure regulator. An additional hose (sold separately) will then carry the propane from the high-pressure regulator to the 2-stage regulator on the driver's side of your trailer.


Bypass Mode for Safety

This Type 1 connector will go into bypass mode if the flow rate surpasses the maximum flow capacity for this connector, which is 450,000 Btu per hour. A ball inside of the fitting will push an internal spring down, pressing firmly against the bottom of the fitting to shut off the flow of gas.


When choosing a Type 1 connector, consider your overall propane demands and choose a connector with a flow rate that just exceeds it. That way, you won't trigger the bypass mode during normal use, but it will trigger in the event of a leak. If the bypass valve engages, stop using gas and start checking your connections for leaks.

I have purchased two of these and they both failed the same way. They are supposed to have a back flow preventer so you can disconnect one tank and refill it while leaving the other tank on. In both case, when disconnected from the tank, the gas leaks from the other tank. I am looking for a functioning alternative.

Hmmmm, this could be due to your regulator. I do not see any information of your set up in the notes on your order. Can you please provide pictures of your set up? If your regulator is not lowering the PSI, then it could be blowing out the check valve in the hose.

@KatrinaD The third one I put on worked as it should. Now I can disconnect a tank for refill and not have to turn the other tank off to prevent leakage. These are designed to have a “backflow” preventer in them to prevent leakage when disconnected. The others apparently malfunctioned but all is good now.

@WayneT Glad to hear it worked out. Hopefully the defective check valves did not cause you too much of a headache. We will definitely keep this in mind going forward. Thanks again for taking the time to share.


by:

Previous pigtail hoses were 10 years old, and shot. Bought these- they are a couple of inches longer than the older ones, but- worked great. Did have to tighten them up pretty good before I stopped smelling propane, but- probably more a function of me not using the yellow thread tape. May unscrew these and put the thread tape on them. But in any event- work great!

Still working great. Did use yellow thread tape for a solid connection. Would buy again



by:

I'm sure this product is probably good and would work well, however it is the wrong pigtail for me. I thought I needed this pigtail with the 1/4 inch NPT fitting, but that size fitting is the wrong size, so I will have to return it.



by:

Lp hoses worked great. Old one were manufactured back 2009,so it was time to change them. Found out I also have a bad tank valve on one of my tanks. Great service and knowledgeable crew. Thanks

Added GasStop valves on my Air Stream and needed longer pig tail hoses due to limited space. Ordering on line was easy, delivery was timely, and they fit as expected.

the hose and the regulator with the gas tape was installed. We are now safe in our 5th wheel from a propane leak. I had to get a neighbor to help as I didn't have enough hand strength to get fittings tight. etrailer helped me get all the right parts to make this happen.

Great fittings were exactly what I wanted



by:

We were traveling and one of the High-Pressure regulators on my RV went bad - it was leaking noisily (sounds like a high-pressure hiss). My 5th wheel has two 30 lb tanks, one in a compartment on the driver's side and the other on the passenger side. Respect the dangers of propane but it was easy to replace. I have ordered many RV and trailer parts from etrailer in the past and was never disappointed. etrailer had the parts and delivery was fast - they are great. Be sure you get the right pressure regulator (mine was 30 psig and required 1/4" inlet and 1/4" outlet. The hose or outlet might look big, but these are 1/4" ID. I also needed the hose from the regulator to the propane tank. Be sure to get the right hose as they come in a variety of lengths and different pressure ratings (identified with a Black, Light Green or Dark Green knob) that connects to the propane tank. Apply 3 or 4 turns of yellow Teflon tape to the threaded end of the hose before inserting into the pressure regulator. Don't use white Teflon tape, which is for plumbing; yellow tape (etrailer 37207-30025) is thicker and is for propane. Install the pressure regulator correctly. The little ring on the outside edge of the pressure regulator must be installed pointing toward the ground. The installation took about 20 - 30 minutes. Don't forget to test for propane leaks. Respect the dangers of propane.



by:

Good quality hose. Perfect replacement for my old degraded hoses (one was leaking). Bought the longer 20” hose to allow for a loop to reduce stress on the hose crimp connection where old hose leaked.



by:

Just entered make and model of my trailer and searched for propane fittings. Picked the one I wanted, and it was shipped quickly and fit perfectly.



by:

I bought these so I could mount the propane tanks on my trailer with the valves facing outward. Now they don't drag on the tank cover.

OK Here we go, I have been dealing with ETRAILER for many many years .They are my go to parts company for all my rv ( MH and TT ) items I need. I run an RV park at the entrance to Death Valley National Park in Nevada I deal with 1000 of RV ers a year of which some need parts.or information I recommend ETRAILER and I follow up with them because I want to know how things worked out for them after all it was on my word they went to ETRAILER, and i,m from the old school folks where a persons word is everything. Not one person had anything bad to say about ETRAILER and they thanked me for telling them about them .So if your in a spot give them a call they will work with you..Just plain good people there.

Perfect fit for my trailer propane bottles. Great customer service. Responded very quickly to my inquiry on delivery tracking.



by:

Looked to be quality replacement LP hose, installed, leak checked, no leaks. Note to etrailer, in one of your answers to Q&A you state to use white Teflon tape on fittings. You need to change that, white is not compatible with propane, it should be yellow (some blue is if so labeled).

The short, 12 inch, original propane hoses on my toy hauler made it difficult to access and remove the tanks for refill. The new 20 inch long hoses I ordered and installed make removing and refilling the propane tanks much easier. Good product, good price. Thanks.

Initially had purchased pig tails made by a competitor, but had not installed them. After reading reviews of MB Sturgis's product I returned the previously purchased hoses and installed the Sturgis pig tails. The Acme fitting and hose crimps seem to be of much higher quality Quick shipping from etrailer!

  • What Hose and 2-Stage Regulator Do I Need for My Travel Trailer?
    The fitting you need is a type 1 like the MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 20" # 100473-20-MBS. As far as the regulator, I recommend the Camco Vertical 2-Stage Propane Regulator - 160,000 Btu/Hr # CAM59313. If you need the supply hose, that is the # 37207-31255. It is important to note that this supply hose is for the standard 3/8" male fitting on the manifold.

  • Adapter Needed To Go From 1/4" Male Inverted Flare Fitting To 1/4" Male NPT Fitting
    If you're looking to go from a 1/4" male inverted flare fitting to a 1/4" male NPT fitting then you could use the Propane Adapter Fitting # 37207-30035. If this is not what you're looking for then I'll need to know the size and fitting type you're trying to connect to. I've also attached a little guide below that explains each fitting type if you're not too familiar with RV propane.

  • Is the Humming From My GR-630 Regulator Bad and What Parts to Replace It
    The noise you're hearing is likely coming from your GR-630 regulator, and it's not a sign of anything actually being amiss; the humming noise is caused by the rubber diaphragm inside the regulator fluctuating normally to keep up with the steady demand of regulating the flow of propane to the appliances. For the vertical vs horizontal regulator situation, it doesn't really refer to the mounting orientation, but where the vent on the regulator is positioned. If the vent is perpendicular to...

  • Replacement Propane Parts For 2016 Jayco Trailer
    It sounds like the check valve on your regulator has come apart. Those are necessary for the operation of the propane system so you will need a new regulator. You may not have a leak on the hose and find out that the regulator was the culprit all along, but it is always safer to replace the hose as well. If the # 100473-20-MBS has the correct fittings, you may need a single stage regulator like part # CAM59013. This regulator has a 1/4-inch NPT inlet and a 3/8 inch NPT outlet connector...

  • Will Camco Dual Regulator Allow Disconnection of One Tank for Filling While Utilizing Other Tank?
    The Camco Automatic Changeover 2-Stage Propane Regulator for Dual Propane Tanks # CAM59005 will allow you to keep the system up and running off the other tank as you remove the empty tank for filling. The regulator will automatically change over, but the pigtail like # 100473-20-MBS will also have a built in backflow preventer to keep your system from leaking gas, so you have 2 product working to protect you from issue as you refill your propane tank.

  • Availability Of Propane Pigtail With 1/2" NPT
    Hello Patti. We actually do not carry any pigtails with a 1/2' NPT fitting. We could supply you with a 1/4" pigtail but it would require you to find an adapter to go from a 1/2" NPT to a 1/4". We do not carry any such adapters here, but you should be able to find one at a local propane supply/hardware store.

  • Propane Hose To Replace A Marshall Gas Model 242-1752
    I was able to find a little bit of information on this Marshall 242-1725. The info out there is pretty limited, but it appears it is a standard pigtail with a type 1 and a 1/4" NPT. If so you can replace it with a pigtail like the # 100473-20-MBS which is 20" long. Generally this will be plenty long to get from your tank to a regulator.

  • 12 Inch Propane Supply Hose for 20 Pound Propane Tank
    Assuming that the 1 pound bottle can be removed and that the regulator on the grille can be used with a 20 pound tank then for a 12 inch supply hose you would need # CAM59053. It has a type 1 ACME nut at one end that connects to an ACME or P.O.L. connection on a propane tank. The other end is a 1/4" inverted male flare that connects to a 1/4" inverted female flare on a propane regulator.

  • Troubleshooting No Propane Flow On Trailer with New Tank and New Regulator
    Yes. The pigtail could be the issue. I recommend replacing the pigtail with the MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 20" # 100473-20-MBS. There is an internal back-check on Type 1 fittings that could be the issue.

    The type 1 ACME hose like part # 100473-20-MBS that connects the propane tank to the Camco Automatic Changeover 2-Stage Propane Regulator part # CAM59005 has a built-in back check valve therefore you will not need to use anymore with this regulator as long as the type 1 ACME hose you are using has this feature (it should). There will need to be one back check valve on each side of the regulator.

If you prefer you can install Camco Propane Fitting # CAM59953, which has a 1/4-inch male NPT fitting on one end, and then use the 1-foot Supply Hose # CAM59053 you already have which will connect to the fitting.

    Yes, the # 100019-24 pigtail can be used to connect your dual-cylinder 100 lb propane setup to the regulator on your RV. Since this hose does not have a back-check to contain a gas leak, you will need the # 204120-MBS fitting that includes a back-check.
