1/4″ Brake Line Fitting Kit (16-Piece)

The 4LifetimeLines® 1/4″ Brake Line Fitting Kit (LTSFK250) delivers every SAE tube nut you need to fabricate, repair, or modify your brake-line system. Machined to precision from corrosion-resistant alloy steel, these fittings thread onto properly flared 1/4″ tubing—whether you’re working with steel, stainless, copper-nickel, copper-coated, or PVF-coated lines—for leak-free, DOT-compliant connections you can trust.

What’s Included

You get a total of 16 tube nuts in the most popular SAE sizes for 1/4″ lines:

2 × LTN13 (7/16-24 inverted)

10 × LTN16 long (7/16-24 inverted)

2 × LTN34 (9/16-18 inverted)

2 × LTN35 (1/2-20 inverted)

Each nut features standardized SAE flare threads and wrench flats for easy installation with common flare-nut wrenches.

Why You Need This Kit

Rather than tracking down individual fittings, this compact assortment keeps your toolbox ready for any brake-line job. Precision threads eliminate mismatches and leaks, while marine-grade alloy resists pitting, galling, and corrosion—even in salt-belt or coastal environments. Backed by our lifetime warranty, this kit ensures you always have the right tube nut on hand to finish every repair or custom run quickly and reliably.
