Philmac Reducing Coupling – IPS-OD | Connect Two Different Sizes of IPS-OD PE Pipe

The Philmac Reducing Coupling IPS-OD is a compression-style fitting that connects two sections of IPS-OD polyethylene pipe of different diameters. When your water system transitions from a larger main line to a smaller lateral, or you need to step down pipe size at any point in your system, this reducing coupling makes the connection securely and without leaks.

Philmac’s compression fitting technology grips both pipe ends mechanically — no threading, no solvent welding, no special tools beyond a standard wrench. The reducing design handles the size transition cleanly, maintaining a reliable, pressure-rated connection at the joint. It’s the fitting you reach for when your pipe sizes don’t match and you need a dependable solution fast.

Available in multiple size combinations to match your system’s requirements, the Philmac IPS-OD Reducing Coupling is a trusted component in agricultural water systems across the country.
