ProPress 2915.3 Copper Slip Coupling

This copper slip coupling joins two 1-1/4 inch copper tubes using press-fit connections on both ends. It is designed for potable water systems and carries an EPDM O-ring seal. The fitting has no centre stop, allowing it to slide fully over a pipe for repair work. Overall length is 2 7/32 inches.

Press-Fit System Limits

The coupling is rated for a maximum operating pressure of 200 psi in potable water applications. It requires a compatible press tool and jaw set to form a permanent, leak-free joint; soldering, threading or compression methods cannot be used with this fitting. Copper tube must meet the correct diameter and wall-thickness tolerances for the press profile to seal properly.

Installation And Common Issues

A calibrated press tool is essential; an incorrect jaw size or incomplete press cycle will leave an unsealed joint. Because the coupling lacks a centre stop, the installer must mark the insertion depth on each tube to ensure equal engagement. Debris or scratches on the tube surface can damage the EPDM O-ring during insertion.
