  • Overall length 8 47/64 inches for compact runs

3 in PVC Compression Coupling

This ZORO SELECT coupling joins two sections of 3 in Schedule 40 PVC pipe using compression ends on both sides. The 8 47/64 in overall length provides a straight, female-to-female connection for drainage or low-pressure water lines. It is built for standard Schedule 40 dimensions and installs without solvent cement.

Operating pressure and temperature range

Rated for a maximum operating pressure of 150 psi, the fitting handles typical residential and light commercial water supply demands. The PVC body is suitable for continuous service between 32 and 113 degrees F, covering normal cold-water and moderate hot-water conditions. No additional seals are included in the package.

Tool-free installation benefit

Compression ends allow the joint to be assembled by hand or with basic wrenches, eliminating the need for primer, cement and cure time. This speeds up repairs and makes the coupling practical for tight spaces where a torch or ventilation would be difficult. The fitting is restricted from sale in certain states.

Questions about this item

How do I install the 3 in compression coupling on Schedule 40 PVC pipe and what step is most often missed?

Cut the pipe square, deburr the ends, slide the compression nuts and gaskets onto each pipe, then insert the pipe fully into the coupling body before tightening both nuts evenly; the step most often missed is fully seating the pipe past the internal stop before tightening.

What maintenance or replacement will this PVC compression coupling need over time?

Inspect the EPDM gaskets periodically for cracking or hardening caused by the 32 to 113 Degrees F operating range; replace the gaskets if leaks appear at the compression joints, otherwise the Schedule 40 PVC body requires no scheduled replacement.

What is the first limit that appears under sustained pressure at the 150 psi maximum operating pressure?

The 150 psi maximum operating pressure is the primary limit; sustained pressure at or near this rating can accelerate gasket creep and reduce seal integrity before the Schedule 40 PVC body reaches its structural limit.
