Looking for 3/8 inch Flare to 1/4" Male Quick Disconnect Hose

Question:

Hi friends, I have a 3/8” male propane supply side after regulator. I want to run a propane line to the rear and end with a email quick connect. That way I can plug my grill into than with another quick connect male when I need it. Can y’all help me with what to order? I think I need a 12’ hose. I’ll zip tie it up under the frame. Thanks!

Hey Aaron, closest option we have would be the MB Sturgis Propane Adapter Hose # 100304-120-MBS which is a 10 foot propane supply hose that has a 3/8 inch female connector on one end and a QD male on other end like you said you wanted.

I should mention that there are pretty particular laws about running propane line and if its going to be on underside of the RV I am fairly certain to be on the legal side of things it needs to be a hard line. Which grill do you have?

Thanks Jameson. I took a chance and ordered a supply line with adapters. Take a look at Order #124255850. I’ll look up the laws. I think my previous camper which was stock had flexible lines under it but laws may have changed and it was old. I guess I could also add a quick connect right off the tank and just run a long hose to the grill when I wanted. It’s a black stone with the regulator removed and a male quick connect already added. Thanks!

@Aaron I checked out what you ordered and that would work too! I could be wrong on the laws on that. I was paraphrasing something I learned in a training whereas what I am seeing online is more that it is highly recommended to use hard lines under an RV.
