Copper Sweat Union for Tubing Systems

This ZORO SELECT union joins two 1-inch copper tubes with cup connections on both sides. Cast copper construction handles up to 494 psi at 100 Degrees F and temperatures up to 400 Degrees F. The straight shape suits standard tubing layouts.

Cast Copper Build and Cup Connections

The bronze-finished body resists corrosion in plumbing installations. Each end accepts a 1 1/8-inch tube outer diameter for sweat soldering. No flange is present, keeping the profile compact for tight runs.

Replaces Worn or Leaking Straight Unions

Use this fitting when an existing union shows seepage or corrosion at the joint. The pressure rating supports typical residential and light commercial lines. Not suited for systems requiring flanged ends or larger tube sizes.

Questions about this item

What pressure does the sweat-union connection handle at 100 °F?

The copper union is rated for 494 psi at 100 °F, which is the practical limit for the sweat fitting joint.

What tube size and clearance does the 1 in cup fitting require?

Each cup accepts 1 in copper tube with a 1 1/8 in outer diameter, so allow space for that OD when routing the straight union.

How is the bronze union installed and what step is often missed?

Clean both tube ends, apply flux, slide the union on, then sweat-solder the joints; the step often missed is heating the fitting evenly so solder flows completely around both cups.
