4LIFETIMELINES – 1/4" x 25' Copper-Nickel Brake Line Kit with 16 SAE Fittings | True CuNi Alloy, Non-Magnetic | Inverted Flare, 0.028" Wall | Rust-Proof Replacement Tubing for Cars & Trucks

Worked great for running new brakes lines on my truck. Bends nice without any kinking problems and flares easy with a basic flare kit. Non magnetic and seems to be good quality. Will buy more. Tried cheaper copper coated brake lines but they rust out fast. This is the way to go.

This ni-copp tubing is super easy to use. Unroll it against a piece of cardboard on a flat surface. Cuts and flares easily, bends much easier than steel and is less likely to kink (though you still need to be careful). I strongly suggest the Mastercool hydraulic flaring tool set, pricey but works every time. The included fittings can be helpful, but would be even better if included a handful of unions (AGS BLU-4 equiv). If you are patching lines on European cars you'll be salvaging the tube nut off the old line and using your bubble flare tooling, then using two of the included inverted flare nuts with a threaded union , and with a 45 degree double flare on the remaining section of steel line and on the end of your nicopp line. This tubing looks pretty when it is new, but after one season on New England salted roads it turns an ugly greenish color. The integrity of the tubing remains fine, but the (steel) fittings get nasty just as you might expect.

Easy to work with, flare easily.

Reasonably priced 1/4" brake line tubing kit, works as intended. Just an FYI most people will want the 3/16"/4.75mm ( CNF-3 ) sized kit since it's what is found on virtually all cars and trucks made in the world. The 1/4" ( CNF-4 ) brake line is most frequently found in cars and trucks in the 50's, in the short pieces between the master cylinder and ABS pump and the long run to the rear of full sized cars, trucks and hydraulic clutch lines. ( Typically you don't need 25 feet of 1/4" when working on a <= midsize vehicle ) Bare in mind when looking for brake lines that the brake lines should conform to international brake tubing specifications SAE J1650, BS 2871, ASTM A254, SMMT C5B and DIN 74234 and the late model GM and most European built cars the larger line will be 6mm ( CNF6mm ) not 1/4" ( CNF-4 )...

I was happy with product. But, the fittings did not work for my 2007 yukon denali.

Used this Tubing and some of the Fittings on a 2003 Chevrolet Astro Van to replace the entire original brake tube from the ABS module to the passenger front wheel. This tube is very easy to work with, it's flexible and easy to bend, but ridge enough to maintain all the bends that were required. The Fittings worked very well at the ABS module connect and at front wheel flex hose connect. The Tubing and Fittings arrived on the date promised and were well packaged. I will purchase from this seller again in the future if needed.

I've been using this brake line now for 6 months professionally. I have not had to replace it after I've installed it and I've had no problems with installation, thickness, build quality, or flexibility. I would recommend this for your backyard mechanic all the way up to professional

Always a good chouce

Really liked that the fittings are included in this kit.

Great line good price and easy to work with, came with lots of fittings.

These are outstanding brake lines that are very easy to work with and form, unlike the stainless steel type witch need to be custom made at times, and can be a real hassle to form. I highly recommend these for all those do it your self people out there!

Right product, on time.

Had the one weird sized bolt I needed
