MuHize 3/16" Brake Line Kit — 25 ft Copper-Nickel Tubing with 16 Fittings, Corrosion-Resistant & Hand-Bendable

MuHize 3/16" Brake Line Kit is a 25-foot roll of flexible copper-nickel tubing supplied with 16 assorted inverted tube nuts for brake, fuel, and hydraulic line repair or installation.

Designed for DIY mechanics and professional technicians, this kit provides corrosion-resistant copper-nickel tubing that bends and flares easily while resisting rust better than standard steel lines. The roll includes a selection of inverted tube nuts in different thread sizes and color-coded finishes to help you identify fittings quickly during installation. It’s intended for use in hydraulic braking systems, fuel lines, transmission lines, and general plumbing or industrial applications where durable, flexible metal tubing is required.

How does this tubing perform compared with steel lines?

The copper-nickel alloy used in MuHize tubing offers improved corrosion resistance and a smooth surface finish that slows rust formation. It remains flexible for hand bending and accepts clean flares without cracking, making it easier to route and join than many steel alternatives.

• Alloy resists corrosion better than plain steel.
• Smoother interior reduces clogging risk and supports consistent fluid flow.
• Hand-bendable for easier routing in tight engine bays.
• Compatible with standard flare tools for secure fittings.

Which fittings are included and how are they organized?

The kit contains 16 inverted tube nuts in four common sizes to match a variety of vehicle and equipment fittings. Nuts are color-painted to help you identify threads quickly and avoid mismatching during assembly.

• 2 x 3/16" (7/16-24) inverted tube nut — typically for specific brake ports.
• 10 x 3/16" (3/8-24) inverted tube nut — the most commonly used size in the set.
• 2 x 3/16" (1/2-20) inverted tube nut — for larger ports or adapters.
• 2 x 3/16" (9/16-18) inverted tube nut — for less common thread sizes.

How easy is it to bend, flare, and install this tubing?

MuHize tubing is manufactured for flexibility so you can shape it by hand for most bends; it also accepts standard flaring tools without work-hardening or cracking when done correctly. The kit is suited for single-run repairs and custom lines where a clean flare and secure connection are required.

• Hand-bendable for quick routing with minimal tools.
• Compatible with basic double-flare or bubble-flare tools.
• Color-coded nuts speed installation and reduce mismatches.
• Works with common brake and fuel line fittings when installed properly.

What applications and vehicles is this kit suited for?

This 3/16" tubing kit is versatile: it’s commonly used in automotive hydraulic brake systems, fuel lines, and transmission lines, and also fits industrial, marine, and household fluid-transfer jobs. Always verify thread sizes and fitting compatibility for your specific application before cutting or flaring the tube.

• Automotive brake line repairs and custom routing.
• Fuel line or transmission line runs where corrosion resistance helps longevity.
• Industrial or marine fittings that accept copper-nickel tubing.
• DIY plumbing or specialty fluid systems needing flexible metal tubing.

Who is this for? MuHize 3/16" Brake Line Kit is aimed at home mechanics, restoration shops, and fabrication specialists who need a reliable, corrosion-resistant copper-nickel tubing solution with an assortment of inverted tube nuts. If you require a flexible, flare-capable tube for brake, fuel, or hydraulic systems—and you want the convenience of multiple fitting sizes in one package—this kit offers a practical, workshop-ready option. Verify thread matches and follow proper flaring and installation procedures to ensure safe, leak-free connections.
