This is a 1/2 inch brass compression union fitting designed to join two sections of 1/2 inch outside diameter tubing.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It creates a leak-tight seal by compressing a ferrule onto the tubing when the nuts are tightened, making it a common repair part for air brake, fuel, and other fluid lines on heavy-duty trucks and trailers. You would replace this when the original union is cracked, leaking, or you need to splice in a new section of tubing without using a flaring tool.
