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.

The crimp fitting on the 1/4" NPT end started to leak a couple of months ago, etrailer would not fix or replace it.

I am sorry to hear that this item started leaking. I see that our customer service department is currently looking into your email you had sent about this leak.
-- Etrailer Expert Katrina B - 11/22/2022


After looking in 3 different hardware and RV parts stores, I looked online and found I kicked myself for not going there the first time. ETrailer always has my rv trailers parts in stock and shipping was quick! I won’t shop anywhere else again.


Great replacement propane hose. No leaks


I needed quick delivery, so I paid extra for shipping. Even though the order process was confusing with regard to the cost of different shipping options, the product was delivered promptly. So far, the hose is working well.


Great company, fast shipping, Hose very well made sould last more then that Chinese made it came with my camper. Thank you!

Been a year now in the hot Florida heat with many uses and still looks new !
Ierolohites - 06/05/2022


I got these so there would be less strain on the fittings at the regulators. The factory hoses were just a tad bit short and one developed a leak at the hose crimp. These longer hoses take all of the strain out of the fittings.


Excellent customer service for a company that offers specialized products you can’t find on the big box places like {online]. Will definitely use again!


Works as designed/expected


Worked great to replace the original on my camper that was leaking.


For me to be able to thread into my RV, I needed to go get a street 90. That solved being able to install.


Perfect fit as advertised


Needed two longer propane hoses for our camper due to installation of new and bigger propane tanks and they fit perfectly. Had a difficult time finding them until I found these from a very large selection on Very happy with the quality. Thank you.


Exactly what was needed


This hose, plus a male quick connect and a 90 degree elbow make a great accessory for the Sturgis tee with quick connects. Using the elbow makes the hose easy to connect in tight places.

This hose + male quick connect + 90° elbow = long term solution to long term parking. It has been in continuous use for a year now.

The prosses went well and delivery was early thank, I have not used the hose but in the fall I hope to use it to extend our gas use as we turn the heat on in the RV it has a small gas tank and this hose should help with our external .


This is my second purchase from As with the first the service was hassle free, fast, and cost effective (both product and shipping.)

I would recommend using and see for yourself.


Arrived quickly


Great service, delivery and part made in USA! Thank you etrailer

Exactly what I needed and it was shipped out the same day I ordered it.. payed for standard shipping (cheapest) and still arrived in only 4 days.

  • Determining Correct Propane Pigtail Hose For Trailer
    Depending on the specific propane regulator on your trailer you will either need the MB Sturgis Propane Pigtail - Stainless Overbraid - Type 1 x 1/4 Male Inverted Flare # 100833-36 or the MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 36" # 100473-36-MBS. The easiest way to determine the correct hose for your regulator has a brass fitting as shown in the included picture or not. If you have the brass fitting you will need the # 100833-36, and you instead connector directly...

  • Propane Regulator for MB Sturgis 100473 Propane Hose
    Yes, you can use the MB Sturgis 100473 hose with a replacement single-stage regulator, which is what it looks like you need based on your photo. For the regulator you will need the Camco Single Stage Propane Regulator # CAM59013. Then for the 100473 hose you can choose the one you need based on the length: - 12 inches: MB Sturgis Propane Hose - RV Type 1 with Back Check x 1/4" MPT # 100473-12 - 15 inches: MB Sturgis Propane Hose - RV Type 1 with Back Check x 1/4" MPT # 100473-15-MBS -...

  • Propane Hose For Camco Single Stage Propane Regulator
    Assuming the regulator is being connected to a propane tank with a Type 1 fitting, you'll need a propane hose with a 1/4" MPT connector to connect to the inlet of the Camco Single Stage Propane Regulator # CAM59013. That will depend on the length you need, and you can use either the 20 inch MB Sturgis Propane Hose # 100473-20-MBS or 36 inch MB Sturgis Propane Hose # 100473-36-MBS.

  • Compatibility of Longer Propane Pigtail Hose on Aliner RV
    The MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 36" # 100473-36-MBS is a great replacement for the part you referenced but it isn't quite as high a capacity. Nothing in a traditional RV will require the 450K BTU lines and your regulator will reduce it to likely so the 400K BTU pigtail will work just fine as a replacement. For instance an extremely common regulator is the Camco Automatic Changeover 2-Stage Propane Regulator for Dual Propane Tanks # CAM59005 which will...

  • Need A 250,000 BTU Dual Stage Auto Change Over Propane Regulator For Pool Heater
    The Compact Low Pressure 2-Stage Automatic Changeover RV LP Gas Regulator # 37207-31525 will let you hook up both tanks and can run up to 262,000 BTUs an hour. This is a horizontal unit so you will need to make sure it is mounted in a horizontal position.

  • Is Teflon Tape or Gas Pipe Sealant Needed for the MB Sturgis Propane Hose w/ Back Check
    Yes, the MB Sturgis Propane Hose w/ Back Check, # 100473-36-MBS has a 1/4" Male NPT thread and should be installed using a Thread Sealant Tape for Gas Lines, such as # 37207-30025 or Gas Pipe Sealant, # 37207-30555.

  • Parts Needed to Connect the MB Sturgis Regulator # 108221 to a 1991 Coleman Sun Valley
    The MB Sturgis Horizontal 2-Stage Propane Regulator # 108221 sounds like it is exactly what you are needing for a replacement regulator. To connect your 20 lb propane tank to the regulator you need a pigtail. Since you have about 3' you need to cover I recommend the 36" MB Sturgis Propane Pigtail # 100473-36-MBS. From here you need a 3/8" MPT on one end and then whatever end connects to your 1991 Coleman Sun Valley. The most popular is either a 1/2" flare swivel like part # 100383-48-MBS...

  • 12 Foot Long Propane Hose to Connect BBQ to Disposable Cylinder Fitting
    The large port on your Extend a Stay, basically part # CAM59113, is a male 1 - 20 disposable cylinder connection. To hook your BBQ grille up using that fitting you can use part # 204132-MBS which is an adapter to a Type 1 fitting. Then use a Type 1 hose with a regulator, like part # CAM57721, that's 12 feet long and has a 3/8 female flare to connect to the grill. If these parts don't have the correct fittings let me know.
