Brass Compression Equal Union Fitting — Straight Tube Coupling
The Brass Compression Equal Union joins two equal-outside-diameter tubes into a single straight, leak-tight run — no soldering, flaring, or special tools required. Simply slide the nut and ferrule (sleeve) onto each tube and wrench-tighten; the ferrule bites down to form a secure, reusable seal. Machined from solid brass for corrosion resistance and long service life.
Key specifications

- Material: Solid brass, corrosion resistant

Applications
Ideal for air compressor piping, shop and instrument air lines, machine tools, mobile and packaging equipment, and non-potable water and fluid-transfer plumbing. Best suited to low- and medium-pressure connections where the tubing is not subject to heavy vibration or movement. Always confirm the pressure and temperature rating of your tubing, as the tube — not the fitting — is often the limiting factor.
Choose the tube size that matches your line and get a fast, dependable connection. These brass compression equal unions are a workshop staple for repairing, extending, or splicing copper and poly air and fluid lines, offered here in eleven sizes from 1/8" up to a full 1".
