Flexible Brake Hose with 90-Degree Swivel

This Kodiak brake hose is made of rubber, making it a practical choice for a variety of applications. Because you can easily bend it, a rubber hose is simpler to work with than a rigid stainless steel brake line. This flexibility makes a rubber hose great for use with foldaway trailer tongues because it is less likely to kink or break when bent. In addition, rubber hoses allow for a wide range of motion so articulating parts can effectively function. These qualities make rubber hoses better suited than steel lines for trailers with torsion axle suspension systems and trailers that have disc brakes.

Kodiak 90 Degree Swivel

And because this hose has a 90-degree fitting on one end, you can install it in tight spaces where there is limited clearance. So you won't have to make a kink in the hose to fit it up against your fender or in any other tight spot.

Stainless steel brake lines have braided exteriors, which can not only wear against exterior surfaces, but also against the interior lining of the hose if dirt gets underneath the steel braid. And if the braid on a stainless steel line tears, it can cut into the hose lining. The exterior surface of this hose is solid rubber, so there are no crevices for debris to enter.

Durable Fittings with Deep Threads

Kodiak brake hoses have corrosion-resistant brass fittings with stainless steel flares. These fittings have a gap built into them that allows room for a line wrench - also called a flare nut wrench - to slide over the line and down to the nut. This type of wrench grips the nut better than a standard open-ended wrench so there is less chance of stripping the threads as you tighten down the nut.

The stainless steel that is used to create the flares on this hose is stronger than brass. As a result, these fittings are more durable than ones made entirely of brass. The stainless flares are primarily designed to keep the fittings from splitting when you tighten them down, but they offer absolute rust protection as well.

Kodiak's fittings have deeper threads than many other fittings on the market to provide a higher thread engagement. Deeper threads offer an advantage when used with fittings that have the same thread depth. These Kodiak fittings will work with most fittings on the market, but when they're used with other Kodiak fittings, the result is a stronger connection with fewer leaks.

etrailer was spot on with their brake parts and service. The quick turnaround caused very little down time!!


Perfect, fits great. Staff was very patient in helping find the right break line hose for me.
Thank you very much


Thanks again for all of the help. Here are some pics of the completed project. From new axels completely new brake system. A completer overhaul on the trailer! Thanks again for all of your help!!! Much appreciated!!!


1 year later, still works good with no leaks. My original line got damage from rubbing against the wheel. I made sure to put install a retainer to keep the lines from touching the wheel. So far so good. No issues with this hydraulic hose.


I recently purchased shoulder bolts for the Dexter brake caliber which came in 3 days down time on my trailer I use for work. Upon completing the Caliper application when bleeding discovered 1 leaking and 1 damaged r rubber line so I ordered 2 which was another 3 days down time then the lines I received needed adapters/reducers as the thread size was not the same to the Caliper which upon ordering took another 3 days of down time. My conclusion is please for business sake return to Will Call pick up, down time kills businesses...


Part was exactly as described online. Arrived quickly and on time.


Perfect fit and great price point compared to other option (different PN but same part).


Fit great. Installed on trailer with all the other brake parts I purchased from you guys. Made for a excellent resurrection of a very neglected trailer. On the road again and safely.

Hasnt been used much as owner blew up his PCM ehgine and I think the whole rig is up for sale, but it stops!

I love disc brakes on our 5th wheel. I didn't plan on a blowout wrecking a brake hose. My advice is to carry spares. These a great and can save a trip.

These should be mandatory for 5th wheels. Put about 15,000 miles on the trailer with no issues
Glenn B - 06/07/2019


Great, rugged hose that fit my Kodiak hydraulic brakes on a Renegade stacker trailer. Keep in mind your suspension travel when measuring your hose length.


I can't see any reason this wont work just fine. It has the required DOT 'approval' stamp and is pretty flexible. With the 90 degree it should screw in the fitting of the brake actuator and make a cleaner bend through the floor of the 5ers basement then the usual hard steel line. I do wish that the rubber cover was a little heavier with some reinforcing ribbing such as what a motor vehicle uses for their hydraulic brakes. Fortunately, it will probably outlast our ownership of the RV

Still working well with the Hydrastar actuator and is holding up well

Installed on my 4winns boat trailer and it works.
My only problem is with the female end.
It is kind of deep and the nut/tubing flare from the master cylinder line almost wasn't long enough to engage the tubing flare at the bottom of the this part. I was ready to file off some of the hex nut surface so it would go in deeper but I tested it and it didn't leak so good enough.


This brake line was just as needed. There are numerous fitting styles for brake lines and the pictures and description on the site were excellent allowing me to choose the correct part.


I ordered 2 18" brake lines with fittings and received 2 22 in lines with fittings i must have not made myself clear


I redid the brake system on my bass boat trailer last year, and used the Kodiak brake lines. I couldn't be happier. Great product, great performance, and great customer service.

I replaced metal lines (along with master cylinder and brake assemblies on the axles) on my 30 year old boat trailer that had gotten gunked up over time. These lines were easy to install, easy to secure to the trailer rails, and have performed flawlessly.

I drove the boat to a lake 250 miles away from home last weekend, and it still stops like a dream.


Quick service, Etrailer found equivalent replacement and got product 3 weeks sooner.


What I needed and delivered fast


Arrived on time and looks like good quality product. Not yet installed. Good price and reasonable shipping rate. Thank you!

Product had held up well. My boat is still stopping on command!
Randy - 05/06/2017


Used this hose to connect my Hydra Star Pump to my 3 axle toyhauler. Made brackets to secure the bottom end of hose to trailer. Just got it hooked up so not sure of vibration but I am comfortable knowing that the hard line will not be subject to vibration and movement. Very Satisfied.


Kodiak hose to finish installation of their disc brakes on 7000lbs axles on a Big Horn 3010 re Rv trailer. All parts where bought from e-trailer and were perfect for the install. Support group is also terrific with any information that I needed. Thanks for a excellent company to do business with!


Great Hose! I had to re plumb my boat trailer as the manufacturer left a 6" long brake line unsupported at all to connect to a female/female hose. I tried auto parts stores for a 3/16" IFT male to male connector and all they could offer was the same 6" brake line. This hose will connect directly to the caliper, eliminating the 6" line.

Absolutely fast shipping and great customer service. Mt order was actually processed on a Saturday after I ordered on Friday night!l


The brake hoses ordered were out of stock. One of the etrailer reps found this as a replacement and it worked out perfectly. I had to use less fittings than first expected.


Great brake hose, worked perfectly on my Renegade car hauler trailer with 8K axles and Kodiak 13" disc brakes.


Great, rugged brake hoses. Mine have held up great over the past year. Even with several tire blowouts these hoses are still holding up strong.


High quality product at 1/3 the cost!
really seem to care about order.
I will definitely order from them again.

  • Is Kodiak Hydraulic Brake Hose BH-3MFS-6 Flexible Enough to Make 90-Degree Bend
    Kodiak Hydraulic Brake Hose # BH-3MFS-6 is flexible enough to be installed inside a 3 x 3-inch trailer tongue and make a 90-degree bend. The metal fittings themselves naturally have no flex but the hose material is very flexible since it is designed to work with brakes on torsion axles which will require the hose to bend and flex continuously as the axle's torsion spindles move. If you check out the linked video you'll see one of our team handling the hose and how easily it bends. We also...

  • Is There a 90 Degree Adapter for the Kodiak Hydraulic Brake Hose
    The Kodiak Elbow Fitting for Hydraulic Brake Hose part # BH-L-3FIF will work with the Kodiak Hydraulic Brake Hose part # bh-3mfs-7. The Kodiak Hydraulic Brake Hose part # bh-3mfs90-1-5 could then be used to attach to the caliper or you could exclude this and the elbow and just use the Kodiak Hydraulic Brake Hose part # bh-3mfs90ff-1-5.

  • Availability of Kodiak Brake Line # BH-3MFS90FF-021
    We do have that part number, but our part number is slightly different for that brake line. For that you'd want the part # BH-3MFS90FF-1-5. This is a 1-1/2 foot long FIF and 90 degree male fitting with stainless flares.

  • Difference Between the Brake Lines # 18018-SF and # BH-3MFS90FF-1-5
    For all intents and purposes there is no difference between the part # 18018-SF and # BH-3MFS90FF-1-5. They are basically the exact same thing. They are basically two different brands version of the same brake line.

  • Replacement Dexter Brake Line 18018-SF Options
    If you wanted an exact replacement for the hose you have we do have the part # 18018-SF available that would work well for you. That being said the part # BH-3MFS90FF-1-5 you referenced has the same fitting size on both ends of 3/8-24 so it would also work for you. It's also the same 18 inches in length.

  • How to Install a Fold-Away Coupler Hinge Kit on a Trailer with Surge Brakes
    In order to install a Fulton Fold-Away Coupler Hinge Kit like part # FHDPB230101 on a trailer with surge brakes you are going to want to use a flexible brake line that runs from the actuator to the t-fitting just before it splits to each braking assembly. This hose can been seen as letter A in the attached photo. The hose can actually be ran through the frame rail you will just need to make sure you have enough slack so it does not put too much tension on the line when the tongue is in...

  • Do You Carry A Flexible Brake Line Longer Than 18 Inches In 1/4 Inch Diameter?
    I recommend the Titan Hydraulic Brake Line with Fittings - 25" Long # T0980100 for a longer flexible hose. This is a 3/8 inch diameter versus a 1/4 inch, so if you were to use it with current 1/4 inch, you'd need an adapter. If you want the 90 degree fitting, you can go with the Kodiak Hydraulic Brake Hose - FIF and 90-Degree Male Fittings w/ Stainless Flares - 1.5' # BH-3MFS90FF-1-5 or the Hydraulic Flex Hose - 18" long # 18018-SF which are both only 18 inches.

  • Availability of 1-Foot Brake Line with 3/8-Inch UNF Fittings
    We offer the Titan Hydraulic Brake Line # T0777300, which is 13-inches long. We also offer # T0776500 which is about 18-inches long overall. These flexible hoses have one male and one female 3/8-inch UNF connector fitting.

  • Will the Kodiak Hydraulic Brake Hose Fit a Titan Premier Disc Brake Kit
    Yes, the 3/8"-24 male fitting on the Kodiak Hydraulic Brake Hose part # BH-3MFS90FF-1-5 will match up to the 3/8"-24 female fitting on the Titan Premier Disc Brake Kit part # T2HRCM10DAC. A 1/8" diameter hose and 3/8"-24 fitting is more or less an industry standard for brakes and will be the same across brands.

  • Brackets and Clips to Mount Kodiak Flexible Brake Like Hose BH-3MFS90FF-1-5
    Kodiak brake hose # BH-3MFS90FF-1-5 does not have that little clip you are referring to and Dexter hose # 18018-SF does have it. For either line I recommend bracket # T0776300. For clips I recommend # T0776400.

  • Recommended Disc Brake Hub and Rotor System for 3,500 lb Axle on Ranger Trailer
    For your 3,500 lb axle conversion to disc brakes we have the Titan Disc Brake Kit and Leverlock Actuator w/ Electric Lockout - Single, 3,500-lb Axle # T4843300 that are my top recommendations. Both come with the disc brake compatible actuator, and everything else you need as far as components. These options are the most popular based on if you have a swing away tongue for more compact storage or not. If you already have brake lines from drum brakes, then you can simply use the disc brake...

    The axle spec didn't come through, but that isn't an issue as Dexter has clear fits for their 7K axles.
