3/16″ Brake Line Fitting Assortment (24-Piece Kit)

Stop hunting for mismatched fittings and streamline every brake-line build with the 4LifetimeLines® 3/16″ Brake Line Fitting Assortment. This 24-piece kit equips you to tackle any hard-line project—from custom brake-line loops and fleet repairs to weekend restorations—using only the highest-grade materials and factory-standard dimensions.

Every tube nut, union, adapter, and cap in this assortment is precision-machined from corrosion-resistant alloy steel, brass, copper-nickel, or PVF-coated steel. That means you’ll thread onto properly flared 3/16″ tubing for a leak-free seal that stands up to salt, moisture, and brake-fluid vapors without pitting or galling. Best of all, every fitting is backed by our lifetime warranty, so you can build with confidence mile after mile.

What’s Included

This 24-piece assortment delivers the core fittings you need for any 3/16″ hard-line installation: tube nuts in four material finishes, straight unions for in-line connections, 45° and 90° adapters for tight routing, tees for branching lines, and threaded caps to seal unused ports. Each part features standardized SAE threads and wrench flats for a precise fit and easy tightening with common flare-nut wrenches.

Key Benefits

Because mismatched or low-quality fittings cause leaks, costly rework, and safety risks, this kit is engineered for exact-fit performance. Corrosion-proof plating and marine-grade alloys ensure every seal stays tight in harsh environments, from coastal salt spray to snowy backroads. The uniform thread pitch and wrench size let you swap fittings in seconds, reducing downtime and parts-on-hand. And by covering all essential connection types in one affordably priced pack, you’ll eliminate multiple small orders and hit the ground running on every brake job.

Applications & Usage

Whether you’re routing a custom brake-line loop, repairing a fleet vehicle in the salt belt, or restoring a vintage chassis, simply cut and flare your 3/16″ tubing, then choose the matching fitting from the kit. Thread on the nut until it seats firmly, tighten to spec, and your system is ready for bleed-down and a hard-pedal test. No guesswork, no cross-threaded failures—just professional-grade results.
