A standard hose isn't long enough to run a brake line from your actuator to your trailer axle. This 20' hose gives you the reach to make that connection without adding couplers or extensions.
Connector Hose for Actuator: 240" 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 Fittings: Brass is more pliable than steel, creating a stronger, leak-resistant seal and resisting rust.
Straight Fitting Design: Both ends feature straight fittings - add a 90-degree adapter (DE94SR - sold separately) for a tight turn.
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.

Hi everybody. Andy here with etrailer.com. Let's take a real quick look together at this DMAX rubber hydraulic brake line. Now, this 240 inch brake line is most often used to connect your actuator to the rest of your hydraulic system. The flexible rubber construction is gonna be perfect for foldaway trailer tongues, disc brakes, and torsion axles, and this is designed for any three sixteenths of an inch brake line. The thread size is three eighths of an inch by 24.
These brass male inverted flare fittings on both ends are gonna make a better seal than steel fittings because typically brass is more pliable. It's gonna help prevent leaks, splits and corrosion. And the one eighth of an inch inner diameter is going to allow for smooth brake fluid flow. This is going to meet the Department of Transportation and SAE Standards for safety. Again, this is 240 inches long.
We do have other length available from DMAX, so if this isn't exactly what you're looking for, take a look at the other options that we have from DMAX, see what's gonna work best for your particular application. I think that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Excellent quality to replace the hoses on my boat trailer that are corroded from saltwater use.
well made fair price
Part was exactly what I needed.
Arrived later then it was supposed too but ok I was not in a hurry.
Product came quickly and was packaged well. I will definitely purchase from Etrailer again when I replace the remainder of my brake lines or any other trailer needs!
The hose and the acuator i purchased are working like they should but the boat is not on trailer. I'm sure it will be fine. Thanks for your help.
Shipping was a day late but hose appear to be high quality. will be installing soon
Very poor quality on these brake lines. The brass fittings cross thread very easily.
Exactly what I needed for my freshwater boat trailer. Seems like it will is very good quality
Nice product, quick shipping.
Fast shipping.
Great follow up.
Got this for my boat trailer great replacement line. I have brakes again
Awesome I finally found some flexible brake lines for my truck. I'm definitely going to be ordering more from y'all. I have a 2001 Toyota tundra and your brake lines have helped me tremendously because before my truck was busting the metal break lines over and over.
Do not order this product. The standard fittings for 3/16 flared brake lines have 3/8"-24 threads. This has something else. I'm not sure what the threads are, maybe they're some metric thread that someone through would be close enough, maybe they were made with really poor quality Chinese dies, whatever the story, the end fittings would not thread into 3/8"-24 fittings, they would start and turn a few threads then jam. Yes, I'm sure it was the firings on the hose which were the problem. I tried multiple fittings from multiple sources which all worked together nicely. I even checked with some good quality US made 3/8" 24 taps and dies The fittings on this hose were the one's which were the wrong size. Also, the flares on both ends of the hose were damaged.
Got it quick and the right part it was easy to install , thank you
Delivered on time, works great.
Worked well as a replacement for failed rigid lines on my boat trailer.
Works great
Product was exactly what I needed, high quality,easy installation and very fast shipping. Will order all my trailer parts here from now on.
Had to replace the brake line on my ez loader boat trailer.
This was a perfect and easy replacement. The fittings hooked up to the existing fluid cylinder and Tee block. Would recommend this product.
Worked great, exactly as described
The DeeMaxx kit worked well after trying to figure out the brake lines and where they should run. Installing the disks was slow at first as I wanted to make sure I was doing it right the first time. Bleeding the calipers was most effective having my wife in the truck, brakes on, brakes off. The test run was a challenge as we live in the mountains and there is very little level ground, not even the Walmart parking lot. The truck and 5th wheel combo stopped quicker than I have ever experience in the 28K miles we have traveled since 2020.

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?
