Your brake actuator sits further back than expected, and a short hose wont reach. This 78" line gives you more length and a 90-degree fitting that clears the frame without pulling at the connection.
Connector Hose for Actuator: 78" line links your brake actuator to the rest of your hydraulic system.
Flexible Rubber Construction: Ideal for foldaway tongues, disc brakes, and torsion axles; handles movement and vibration.
Brass Male Inverted-Flare Fitting: Brass is more pliable than steel, creating a stronger, leak-resistant seal and resisting rust.
90-Degree Fitting at One End: Angled end reduces strain on the rubber hose in tight spaces or sharp turns.
Meets Federal Standards: DOT and SAE Certified for safety and performance in hydraulic brake systems.
Leak Resistant: Rubber hose handles flexing and vibration without cracking or splitting.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the DMAC 78 inch long, 90 degree rubber hydraulic brake line with the 3/16 inch brass male inverted flare fittings. Now this brake line right here is part of your hydraulic brake system. This will require additional lines and fittings, which we do sell separately. But this line right here is typically used to connect an actuator to your main brake line. The hose length again, 78 inches.
And it is a flexible construction, so it is perfect for foldaway trailer tongues, disc brakes, and other torsion axles. They do use brass male inverted flare fittings on both ends. The fitting size is 3/16 of an inch. The thread size on the fittings is 3/8 of an inch by 24. And if you'll notice on this one end, it has a 90 degree bend on the one fitting.
This will help put less strain on the rubber line. The brass fittings do make better seals on your steel fittings 'cause the brass is more pliable and it'll help prevent leaks, splits and corrosion. Now the rubber hose does meet the DOT and SAE standards and the inner diameter on this hose is 11/8 of an inch. But that's gonna do it for a look at the DMAC 78 inch long, 90 degree rubber hydraulic brake line with the 3/16 inch brass male inverted flair fittings.

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?
