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.

MB Sturgis RV Type 1 Connection

Compared with other Type 1 connectors, this dark green MB Sturgis Type 1 connector provides the highest flow rate possible before going into bypass mode. As a result, this pigtail will help to ensure that your propane setup will be able to power all of your appliances, even if they require high-pressure gas.

Type 1 connectors go into bypass mode if the flow rate surpasses the maximum flow capacity for that connector. When maximum capacity is reached, a ball inside of the fitting will push an internal spring down and press firmly against the bottom of the fitting to shut off the flow of gas. This MB Sturgis dark green Type 1 connector not only provides a higher flow rate compared to cylinder connectors of different colors, but it also offers a higher rate when compared with dark green cylinder connectors from other manufacturers.

This item is extremely important on an RV and is often overlooked! Even a small propane leak can be dangerous. It can even build up inside the propane tank cover. When I used my gas leak detector and found a leak in the tank area, I was surprised that it wasn’t due to a loose connection but was due to small cracks in the hoses. Even hoses that are protected under the cover and only 4 or 5 years old, they need to be checked thoroughly and replaced. Not only does this product incorporate safety features, but they are also made in the USA!


Size options, product quality, and shipping excellent. Will use etrailer in the future.


Don’t think I have ever had a company follow up a year later. A hearty well done !!!! Know who I will be ordering from, thanks.


Product was delivered quickly and as described. The etrailer website and team are great. Solid information, easily found.


Service and delivery of the products was awesome


It’s a propane line. It worked without leaks so… it works!


I needed a longer propane hose as I purchased propane tank gauges. These longer hoses were exactly what I needed.


fast service great price



This pigtail propane
hose was delivered very quickly...and the price and quality is awesome. I was camping with my grandchildren a month ago and called an RV center when I discovered I could not use my propane stove because the onboard hose had a leak in it. Local RV center wanted $30 for the same product.

I'm very happy to have found what I was looking for at etrailer. NOt my first order with them and won't be my last.

A year later and it still works flawlessly. No cracks and rubber still supple. Good buy indeed!

Still working flawlessly. I just left another short review. Not much else to say.
Dolores N - 08/15/2018


Made in USA. Well made, installed easily and operates well.


I once again got the wrong hoses…as a matter of fact I got 2 more just like the last 2 that are wrong

I did call Paula and left a message that they were wrong and haven’t heard back yet

I’m not mad, just amazed that I have now gotten 2 orders and they were both wrong

Thank you for bringing this to our attention. Our customer service team should be reaching out to you in the near future.

Product was what I expected. The only issue I had was with the Etrailer Price Pledge.Took numerous emails and phone calls to get it straightened out.


One of the original pigtails was leaking at the tank connection after only 6 months. I decided to replace both of them. They were 12" long and I felt too much strain was placed on the fitting, so I opted for these 15" ones. I'm very happy with the quality of the connections and the flexibility of the hose.


Glad I found e-trailer. These lines were just what I needed to replace old cracked lines. I hadn't been able to find the proper length and fittings anywhere else.


easy ordering. very reasonable shipping & handling cost. quick shipment. product received in excellent condition. In fact I'm going to order another as a spare.

thank you.

It worked well. However, I sold my RV and moved to an apartment. But I did leave the spare with the buyer and gave him your website.

Order received as promised. Product as described.


I loved the handwheel on this hose. It threaded easily and seated with little effort.
However on the first tank change, the super stiff hose spun on the barb fitting and started leaking around the crimp right away, just like every other hose.
I wish somebody would make a flexible hose that didn't leak at the crimp.


I bought this to replace a pigtail on a 2 year old travel trailer that had a slow leak in the swedge next to the tank connection. The factory pigtail was ridgid, soft copper bent easier . This pigtail is very flexible and of course does not leak . I will be buying another to replace the other pigtail even though it does not leak at this time.


Hose met the required application and solved the leaking problem.


Works GREAT! Does just what it is suppose to.


Very happy with the products I've received. As good as you can get before going high dollar. The company response is awesome with easy ordering and billing. The only shortfall I've found was a delay in shipping due to back order of one item, with no notification to me. My inquiry into this was met with prompt response and service. Thank you.


Received the MB Sturgis Propane hose for my travel trailer. High quality hose.
Installed and working great.


I received exactly what I expected and it did the job.


Did the trick,better than OEM.

  • Should Pipe Sealant be Used When Installation Propane Tank 1/4 MPT Pigtail
    Yes you should use some kind of sealant on threaded fittings whether it is the tape or pipe dope. Using the white Teflon tape will work well on installing the propane pigtail top the LP regulator. Just wrap the tape on the threads only.

    It appears the part number you have listed may be a Marshal brand, we do not carry this brand but do have high quality components available from MB Sturgis. The length of hose needed, thread size and type are required to ensure a proper fit for replacement. We have the MB Sturgis, # 100473-12, a 12" hose with the needed Type 1 - Male on one end of the pig tail and a 1/4 Inch - Male NPT on the other. See the attached product review video.

  • Replacement Propane Hose for Marshall HP424
    According to my research, the Marshall HP424 does have a Type 1 connection (which connects to your propane tank) and a 1/4" Male NPT connection (which connects to a dual-stage regulator). So the hose you mentioned will work as a replacement, and there are a number of different lengths if you were in need of one. - 12 Inches: MB Sturgis Propane Hose Assembly - RV Type 1 w/ Back Check x 1/4" MPT # 100473-12 - 15 Inches: MB Sturgis Propane Hose Assembly - RV Type 1 w/ Back Check x 1/4" MPT...

  • Availability of 15 inch Long Propane Tank Pig Tails
    I understand what you are saying and I think you are on the right track. A bit more length from the pig tail would allow the rubber line to be able to loop so that it could tuck down better. We have 15 inch pig tails like part # 100473-15-MBS or even 2 foot long sections like part # 100473-24-MBS.

  • Can Type 1 Propane Connector be Used for Propane Tank with Threads on Outside
    Thank you for the photo! Since your propane tank has the threads on the outside and inside it means that you can use a pigtail with either the POL or Type 1 connection like you're asking about. Swapping over to the Type 1 is a great idea just because it's easier to twist on plus you don't have to mess with any kind of sealant. If your regulator has the adapter on it then I recommend using the MB Sturgis Propane Pigtail - Stainless Overbraid - Type 1 x 1/4" Male Inverted Flare - 15" # 100833-15...

  • Propane Hose Replacements for Regulator
    We do have hoses which may work for you. The MB Sturgis Propane Pigtail # 100833-24 is a type 1 cylinder connection with a 1/4" male inverted flare. This is a 2 foot hose, though we also have a 15" hose # 100833-15 and 1 foot hose # 100575-12-MBS. These hoses are also available with back check, the 20" # 100473-20-MBS, 15" # 100473-15-MBS and 12" # 100473-12.

  • 15" Hose For 100 lb Propane Tank With POL Fitting & 1/4" Male NPT Fitting
    We do have an option for you, though the # 100473-15-MBS has a Type 1 fitting one one end and 1/4" Male NPT fitting on the other; the Type 1 fitting does not connect to a 100 lb propane tank, as those tanks have a POL fitting. Though there are no tanks with a Male POL fitting and 1/4" Male NPT fitting, you can use an adapter to get exactly what you need, with the correct parts being the following: - MB Sturgis Sturgi-Stay Propane Fill Hose - POL Pigtail x 1/4" Male Inverted Flare - 15"...

  • Troubleshooting Propane Regulator That Only Works on One Side
    Start off by checking your pigtail. If you change your switch so that it is turned towards the side that isn't working and then swap your pigtails as well this will tell you if you need to simply replace a pigtail or if your have a bad regulator. If you find that it works when you swap the pigtail as well then you just need to replace your pigtail.

  • Propane Hose with 1/4" Male Fitting Does Not Fit Regulator with 1/4" Female Fitting
    From the picture that you attached it looks like the regulator has a 1/4" SAE inverted flare, like the Camco Automatic Changeover 2-Stage Propane Regulator # CAM59005 does. This means that only hoses that have the 1/4" male inverted flare, like part # CAM59053, will fit.
