Copper Nickel Brake Line Tubing

Copper Nickel

Copper Nickel tubing will never rust! This tubing has a wall thickness of .028".

Copper Nickel also bends and flares extremely easily!! If you have a brake line that needs bent by hand this is absolutely the way to go!

Stainless Steel Tubing, Stainless Gravel Guard and Stainless Fittings

Stainless Steel

Stainless steel looks great and will never rust!

Stainless isn't just a great look it's also a great performance product. Unlike Copper Nickel, it does require a higher end flaring tool.

Nylon Fuel Hose

Nylon Fuel Hose

Our Nylon Fuel Line repair kits are an effective and economical way to repair rusted steel fuel lines or damaged nylon tubes.

This nylon tube can be connected directly to original steel tubes on vehicles.

I used a 2018+ honda accord brake booster in my rover. Tesla model 3/Y boosters are the same thing with a different reservoir. These helped me adapt the m12 bubble flares to 3/8 inverted flares to work with the rest of my system. The adapters dont leak. Unrelated to these fittings, but if you're doing the same thing, the wires are pretty self explanatory, youll have power and ground, 4 unused can wires, 4 wires go to the small plug and the purple wire is ignition.

Probably not the most common use but I needed the M12 x 1.0 thread for the fittings on my flow through water heater. The OEM plastic drain plugs were over $15 each and had to be replaced every year when the heater was flushed. I plugged and soldered the through hole then filled the female threaded end with epoxy. Made a pair of perfect plugs.
