Video Transcript for MB Sturgis Propane Hose Review

Hello everybody. This is Jeff at www.etrailer.com. Today I'm going to take a look at this 48 inch long, 3/8 inch, thermal plastic, high pressure hose, with the 3/8 inch female flare swivel ends. Now this is a 3/8 inch inside diameter, general purpose hose assembly, mainly used for LP and natural gas connections. Length I mentioned on this is 48 inches long. I wanted to zoom in and show you on the ends, it does have the 3/8 inch female flare swivel, so you can see how they swivel here, on each end.

And the wrench size that's used to tighten these down is 3/4 inch. Now the hose itself is a thermal plastic construction, which is a plastic polymer, that will become soft when it's heated, and hard when it's cool. And these hoses are typically used to connect portable propane gas equipment to a propane supply, or you can use it for a slide out on an RV to hook to the main piping system. This is approved for all RV use in the USA and Canada. This part is made in the USA.

Now the maximum pressure rating on this hose is 350 PSI. Temperature range is -40 degrees Fahrenheit, up to 140 degrees Fahrenheit. But that should do it for the review on this 48 inch long, 3/8 inch, thermal plastic, high pressure hose, with the 3/8 inch female flare swivel ends..

This is a high-quality made in the USA gas line.
I replaced a yellow corrugated gas line on my gas fire pit. The corrugated line made the gas whistle. This seems much better built higher quality fittings and eliminated the whistle.

Squirrels chewed a hole into my propane hose. RV repair techs didn't want to deal with a small job and referred me to the dealer. Dealer couldn't locate a part number for the replacement. eTrailer showed me the hose that was right for my travel trailer. I had to purchase a couple of brass nipples ($8.00 at Lowes) and some thread sealant. It took me 20 minutes to replace the hose. eTrailer got me the right hose quickly and followed up to insure that it worked well for me. Great service from an online company.
by:
Perfect replacement hose between my frame mounted 100lb tank and regulator. My old hose was pretty rigid from age and after replacing my regulator the old hose developed an ever so slight bubble where the hard rubber met the swivel fitting. Old hose was just too old to remain flexible. This new hose was the exact same length and being new could adapt to the contours needed.

Hi Amy. My wife and I were getting ready for a month-long trip in our 34' forest river travel trailer, when I noticed a propane smell on the left rear of the trailer where the kitchen slide is. after crawling around underneath I found small cracks in the original propane hose. I was pleasantly surprised to find you had the exact hose (length and fittings) I needed to do the repairs. I would recommend rv owners with slides where there is a propane appliance that slides out to check the propane hoses at least once a year. Thanks again.

I haven't attached the new hose yet, but it looks to be exactly what I need! Thanks

@Charlie I am glad we had the right hose for you Charlie. Any fun trips this summer you want to share? I am always looking for new vacation spots, and there is no one better to ask than our neighbors =)

Replaced a 3 Burner stove top in my rv . The shorter 2 ft length was just what I needed without having extra hose to get in the way .
by:
Nice well-made hose. Very flexible.Etrailers price was far better than others.

Still working perfectly. Good product at a good price.

by:
I bought this hose less than a month ago. Has been in use for 3 weeks. I noticed a severe bulge in the outer jacket while checking something completely unrelated. I consider myself fortunate that I caught this before it burst as it could have resulted in a significant danger to my family and those near us. The quality of this hose is HORRIBLE. DO NOT BUY!!
