38" Line is often used as a jumper on tandem-axle and triple-axle trailers. Brass fittings won't rust and are easier to work with than stainless steel.

Hi, everybody, Andy here with etrailer.com, and today we're gonna take a real quick look at this DMAX 38-inch long rubber hydraulic brake hose. This flexible brake hose (hose thudding) (hose swooshing softly) is going to act as part of your trailer's hydraulic braking system. It connects your hydraulic brake actuator to your trailer brakes when used (hose thudding) with additional lines and fittings, which are sold separately. And that flexible design (hose swooshing softly) is going to make this hose perfect for use with your foldaway trailer tongues, disc brakes, and torsion axles. This rubber hose is going to meet the DOT (hose clicking) and SAE standards. And as you've no doubt already noticed, this does include three sixteenths of an inch brass male inverted flare fittings on either end.
And brass is softer, to provide a better seal than steel fittings. And the hose length from end to end, and I went ahead and confirmed the measurement before our time together, is 38 inches long. And that inner hose diameter is one eighth of an inch. (hose thudding softly) Well, that's gonna conclude our brief look today, I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.

I think you may have received either a damaged one (which you did mention) or a defective one, Andrew. I just grabbed two of these at random from our warehouse and test fit them in three different parts and they fit fine. If you would like, I can get a reshipment moving for you so we can get you one that I know fits. And out of curiosity, what are you putting this in? The brake, the actuator, or an adapter/t-fitting?

Thanks for your review, Evan! It sounds like the installation had a bit of a learning curve, but we're glad you took the time to get everything routed and set up correctly. It's great to hear the DeeMaxx kit delivered the stopping power you were looking for, especially with your truck and 5th wheel combination. Thanks for including the photos as well. They'll be a valuable resource for other customers considering a similar upgrade. What trip are you looking most forward to this summer?
