Hi, everybody, Andy here with etrailer.com. And today, we're gonna take a look at this DeeMaxx 220-inch-long rubber hydraulic brake hose. This flexible rubber brake line acts as part of your trailer's hydraulic braking system. It connects your hydraulic brake actuator to your trailer brakes when used with additional lines and fittings. And of course, those are sold separately. And the flexible design makes this hose perfect for use with your foldaway trailer tongues, disc brakes, and torsion axles.
The rubber hose does meet the Department of Transportation and SAE standards. And as you can see here on either ends, we have three sixteenths of an inch brass, male, inverted flare fittings. And brass is softer to provide a better seal than steel fittings. And the total hose length from end to end is 220 inches and the inner diameter of the hose is one eighth of an inch. So that's gonna conclude our 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?
