Flexible Rubber Brake Hose

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.

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 Hose Flare

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.

The two hoses that I ordered fits absolutely perfect. I couldn't have asked for anything better. I checked local auto parts dealers and none had what I needed. Thank you so much for your outstanding service and reliability. I have your internet page my saved on my computer so if I ever need anything else you can be assured I'll come to you.


Perfect size and length for what I need on the trailer. High quality line


worked perfect, Shipping was fast


I went to two of the three auto parts stores in our little town thinking that a plain brake hose could be had. Turns out that brake hoses these days are all model specific and the clerks politely refused to help me without a part or model #. So I searched the internet and finally found exactly what I wanted here at etrailer. Not only that but the price was very fair and shipping cost was surprisingly low. Delivery was prompt and the after sale follow up from the folks at etrailer gives me chuckle...I ain't never seen this kind of "takin' care of business" for a little $26 order like mine was. This e-business is a "favorite".

Great!!! Well, wish I could give a more definitive report, but the fact is that these parts were installed on a boat trailer and the trailer was used to fetch the boat at a hundred miles distance and now has been sitting in the drive way ever since, due to winter. Will soon be moving it around a bit.

hydraulic hose has been in use over a year now. flare connections and hose are good quality . no leaks

Hose is still in good condition no issues

Super heavy duty. Badass fittings. Worth every penny.


These were the brake line hose running to both axles.

These hoses fit perfectly, just what I needed.
Gary H - 06/14/2016


It's a hose what can I say about this hose.... it help finish my boat trailer brake project. etrailer got it to me in just a few workdays, ordered on Thursday installed it Monday. It doesn't leak fluid so that's a plus.


Great replacement for my boat trailer disc brake line. Much, much more durable than the OEM line.




Absolutely perfect for my project!


Very well designed hose. The short stainless tube connectors on either end are easier to connect than a hose that terminates with brass fitting alone.


think gonna work perfect for disk brake conversion on my trike.thanks

Very well made and exactly as shown. Quick shipping and I will order again if the need arises. Thanks eTrailer!!


This part is very good quality. I used it to replace a piece of brake line that had a flex coupler built into it on a 1999 Dodge Caravan.


I wanted these because of the design, being able to get a line wrench on them.

Must be working good because Im having no problems.

These seem to be a good quality brake l ine.

Great product. Works well and easy to install


Product arrived and was exactly as ordered. Shipping was fairly quick even using the base shipping method.


Working fine thanks


The items were exactly what I needed and were at a reason able price.

  • Option for Getting 21 Foot Long Flexible Brake Line Section
    If you need a section of flexible brake line that is longer than the # bh-3mfs-20 you would want the part # bh-3mfs-24 which is 24 feet long instead. I wish we had a 21 foot long section but you would either need to use the 24 foot section or add a 1 foot section to the 20 foot section with part # bh-3mfs-1.

  • PSI Capacity of Kodiak Trailer Hydraulic Brake Hose
    According to my contact at Kodiak Trailer, their # BH-3MFS-1 Rubber Brake Hose has a minimum psi rating of 3,000 lbs. To put that in perspective the Drum brake master cylinder will put out between 1,000 and 1,200 psi and the disc brake systems 1,600 psi.

  • Replacing Hydraulic Brake Line and 90-Degree Fitting on Trailer
    As long as clearance isn't an issue you can certainly do away with the existing 90-degree fitting like what's included with # BH-3MFS90-1-5 and go with a straight fitting right to the caliper instead. We do have a shorter 1 foot brake line available with the Kodiak part # BH-3MFS-1. This flexible rubber line features 3/16 inch brass fittings on each side and the hose itself has a 1/8 inch inner diameter. I have attached a short video review that you can check out as well.

  • Availability of Boat Trailer Brake Line with Male Fittings
    You can click on the linked page to see our brake lines and brake line kits for boat trailers. You'll first select either disc or drum brakes using the filters on the page. We offer brake lines on their own, such as the 1-foot line # BH-3MFS-1 from Kodiak that uses 2 standard male flare nut fittings or their 6-foot # BH-3MFS-6. Lengths up to 24-feet are offered, part # BH-3MFS-24, and these are also available in kits like # 24TA-BLKIT which is for tandem-axle drum brakes. We do not offer...

  • Replacement Brake Line/Hose for Dexter 8K Disc Brake Axle
    There are several brake lines in varying lengths and sizes between your disc brake assembly and the surge brake coupler on your trailer. I am not sure which one you are looking for but if you can pinpoint this for me I may have some better advice for you. In the meantime, I have attached for you a photo that shows what brake lines go to and from a disc brake assembly and surge brake coupler on a tandem axle trailer.

  • Brake Line Extensions For 24' Kodiak Hydraulic Brake Line Kit # 24TA-BLKIT
    I recommend using the Kodiak Union Fitting # BH-C-3FIF to add either the 1' # bh-3mfs-1 or 2' # bh-3mfs-2 of hose you are going to need. We currently do not carry the hoses you are needing in a slightly longer length than those that are in the 24' Kodiak Hydraulic Brake Line Kit # 24TA-BLKIT.

  • Rubber Versus Steel Brake Lines for Electric Over Hydro Conversion on Single Brake Axle Trailer
    As an installer, I much prefer rubber lines as they are easier to use. The steel lines are more durable but I can't say I've ever had a trailer we worked on come back with a broken rubber hose either. The steel lines are very hard to work with and if you want it to look decent you'll have to cut the lines to your exact length and flare on the fittings again. If you're experienced with brake lines and have the time to do it right and make it look nice then the steel lines work well but even...

  • How to Pick Out Replacement Slip On Rotor, Caliper and Brake Line for Trailer
    Sounds like you have an over-the-hub style of disc brake setup on your trailer. To pick out the correct replacement rotors will require you to measure the diameter of the rotors you currently have and know the bolt pattern of the hubs as well. With that info you can check out the link I attached to see all of the over the hub rotors we offer. To pick out the correct replacement caliper will require you to know the brand of your current brakes so that I can pick you out the correct one....

  • Replacement 18 Inch Long Brake Line with Male and Female 3/16 Inch Fittings
    For a replacement brake line I recommend the Titan Hydraulic Brake Line with Fittings # T0776500. This brake line is 18-25/32" long, has a male and female end, and has 3/8"-24 UNF fittings. The thread size on 3/16" fittings is 3/8"-24 so this will be the same as the hose you have now. I have attached a review video for your reference.

  • 18” Rubber Flex Brake Hose w/ a 3/16” Male Fitting
    Yes, we do sell 18” rubber flex brake line for trailers with 3/16” male/male fittings. It is the Kodiak Hydraulic Brake Hose - 3/16" Male Fittings w/ Stainless Flares - 1/8" ID - 1.5' item # bh-3mfs-1-5.

  • Flexible Brake Hose with Swivel Fittings on the Ends
    The ends of brake hose # T0776500 are fixed and do not swivel. Normally on the components you are threading this onto one of them would have a swivel so you would thread the hose onto the fixed component first and then attach the end that threads onto the swivel. We also have hose # 18018-SF with a 90 degree bend on one end and the thread piece separate. Kodiak hose # BH-3MFS-1-5 has swivel fittings on both ends and it is 18 inches long so it may be the best option for you.

  • Recommended Parts To Convert Drum To Disc Brakes On EZLoader Trailer With 3,500 Lb Axle
    To convert your EZLoader trailer to disc brakes you will need a couple things. I called my contact at EZLoader and with the VIN you supplied they told me you have a 3,500 lb axle on your trailer and they told me what size bearings your trailer uses. To convert your trailer to disc brakes I recommend the Kodiak Disc Brake Kit, part # K2HR35D. This is designed for wheels 13 inches and larger with a 5 on 4-1/2 bolt pattern, and with a 4-bolt brake mounting flange. The inner bearing has...

  • 30 Foot Trailer Tandem Axle Brake Line Kit Recommendation
    For a 30 foot brake line kit you would need the part # HS496-251 for the first axle and then to tee into this kit for the second axle you would need part # T0778500 and then use the single axle kit part # DM5402 for the second axle lines. Everything of this kit would be used minus the main feed line, but you would need the part # # BH-3MFS-1 to go from the first axle to the second.

  • Parts Needed to Add a Third Brake Axle to a Trailer
    To tee into your current brake setup you would need the part # T0778500. This would need to get added to the main brake feed line of your trailer. From there you would want to use a single axle trailer brake line kit like the part # DM5402. Basically everything from this kit would get used minus the long brake line. Basically the tee that you add in will go to the new brake assemblies and then using a flex line like part # BH-3MFS-1 back to the original axle lines. For stainless rotors...
