MuHize 5/16" Brake Line Tubing 25ft Roll — Flexible PVF-Coated Copper-Nickel, Easy Bend & Flare

This 25 ft coil from MuHize combines a corrosion-resistant copper-nickel alloy core with a protective PVF (polyvinyl fluoride) coating to deliver a pliable, durable tubing solution for hydraulic braking systems, fuel and transmission lines, and general fluid routing. The tubing is sized at 5/16" (approximately 8 mm) and sold as a continuous roll without pre-attached fittings so you can cut, bend, and flare to fit your vehicle or project needs. It’s engineered for easier hand bending and straightforward flaring with commonly available tools, which helps speed up installation and repairs.

How does this tubing make brake and fuel line work easier?

The MuHize tube is designed for flexibility and ease of shaping so technicians and DIYers can form clean runs without constantly swapping tools. Its PVF outer coating reduces scratching during handling and helps the tube slip through tight routing paths.

• 25-foot continuous coil lets you measure and cut exact lengths on site.
• High flexibility for hand bending and quick routing around brackets.
• Compatible with standard flaring tools for single or double flares.
• PVF coating protects finish and eases installation in confined spaces.

What makes the material corrosion resistant compared with plain steel?

MuHize uses a copper-nickel alloy core which resists rust and corrosion better than unprotected steel. The PVF outer layer adds another barrier against moisture, salts, and road chemicals, helping preserve flow integrity and appearance over time.

• Copper-nickel alloy resists pitting and rust in wet or salty environments.
• PVF coating prevents surface corrosion and abrasion damage.
• Suitable for use in exposed routing where road spray is common.

Can I use this tubing for fuel, transmission, or other systems?

Yes—this 5/16" tubing is specified for multiple fluid systems including hydraulic brake lines, fuel supply lines, and transmission cooler or line routing, provided you follow correct fittings and installation practices. It is sold without fittings so you can choose compatible connectors for the application.

• Appropriate for brake, fuel, and transmission line applications when properly flared and connected.
• Works with standard automotive flare nuts and fittings after cutting to fit.
• Also suitable for household, industrial, and commercial fluid-routing uses.

How should I cut, bend, and flare the MuHize tube for a safe install?

Use a high-quality tubing cutter for square cuts, a bending tool or careful hand bends to avoid kinks, and a suitable flaring tool for the required flare type (single or double). Follow vehicle manufacturer torque specs and routing clearances for safe, leak-free connections.

• Cut with a tubing cutter to ensure a clean, square end for flaring.
• Bend gently or use a spring/bender to prevent kinks in tight turns.
• Flares reliably with common single/double flaring tools; ensure proper seating.
• Secure lines with clamps and keep them clear of heat and moving parts.

Who this is for: MuHize 5/16" Brake Line Tubing is aimed at professional mechanics, restoration shops, and experienced DIY enthusiasts who need a long, flexible, corrosion-resistant tubing option for brake, fuel, transmission, or multi-purpose fluid routing. It’s ideal when you want to cut custom lengths, choose your fittings, and prioritize durability and ease of shaping during installation.
