DOT Compression Sleeve Brass 1/4"
(Pack of 10.0)

Lawson

Create secure, leak-proof connections effortlessly with our brass compression sleeve. Designed for use with copper, brass, and aluminum tubing, this DOT fitting sleeve works seamlessly with a compression nut and fitting to form a watertight seal in low-pressure systems like air, oil, and water lines. Its innovative design eliminates the need for flaring tools—just tighten the nut, and the sleeve locks snugly between the fitting body and nut for a dependable seal. Perfect for plumbing, fuel lines, and various industrial applications, it’s your go-to solution for reliable and efficient pipe connections.
