Description
3/16″ & 1/4″ SAE Brake Line Fitting Kit
Build, repair, or modify your hard-line system without hunting down individual pieces. The 4LifetimeLines® 3/16″ & 1/4″ SAE Brake Line Fitting Kit delivers every union, tee, adapter, and cap you need to create professional-grade brake, fuel, or hydraulic lines. Machined from corrosion-resistant alloy steel and finished to OEM tolerances, these fittings thread onto properly flared tubing for rock-solid, leak-free seals that meet DOT burst-pressure standards.
What’s Included
This comprehensive kit provides eight 3/16″ unions, four 1/4″ unions, four 3/16″-to-1/4″ adapters, two 3-way 3/16″ tees, two 3-way 1/4″ tees, plus matching dust caps for every open end. Live-rubber O-ring seals on the adapter backs ensure instant, maintenance-free tightness, while the precision-cut threads eliminate cross-threading and galling. To top it off, the kit also includes both SAE and metric brake line fitting gauges—so you can quickly identify line sizes and stay prepared for any job.
Precision & Reliability
Every fitting in this kit is engineered for a snug, flare-to-flare connection. When your tubing ends are properly inverted or double-flared, these SAE-standard fittings compress metal to metal for permanent seals that resist vibration, thermal cycling, and corrosive spray. You’ll eliminate drip points and bypass common failures caused by aftermarket mismatches.

Pair it with our stainless or copper-nickel tubing coils and your flaring tool of choice for a turnkey hard-line solution.
