PVC Schedule 40 Repair Coupling

This 4-inch white PVC coupling is built to Schedule 40 specifications for drain and trap systems. It connects two lengths of Schedule 40 pipe using solvent-weld socket ends on both sides. The fitting carries a 150 psi maximum operating pressure rating and is rated for continuous service between 32 and 113 degrees Fahrenheit. It is a new component intended for permanent drainage installations.

Replaces damaged pipe sections

The coupling spans a damaged or misaligned section of 4-inch Schedule 40 PVC pipe without requiring full pipe replacement. Its overall length of 12 7/16 inches provides sufficient engagement on each pipe end to form a reliable solvent-weld joint. The jump from a temporary clamp repair to this fitting is worth it when a code-compliant, leak-free restoration is required for underground or above-ground drain lines.

Handles standard drain flow and pressure

The Schedule 40 wall thickness and 150 psi rating give ample headroom for typical gravity drainage and low-pressure effluent applications within the stated temperature range. The fitting runs out of capacity when system pressure exceeds 150 psi or when operating temperatures fall below 32 degrees or rise above 113 degrees Fahrenheit. It is not suited for hot-water supply lines, high-pressure mains or chemical environments beyond standard residential drainage.

Questions about this item

What length of 4-inch Schedule 40 pipe does the 12 7/16 in overall length coupling span?

The coupling has a 12 7/16 in overall length and uses solvent-weld sockets on both ends to join two sections of 4-inch Schedule 40 PVC pipe.

How do you solvent-weld this coupling without pushing it too far onto the pipe?

Apply primer and cement to both the pipe ends and the coupling sockets, then insert each pipe fully into the socket until it bottoms out; the centre stop prevents over-insertion.

Will the white PVC material withstand continuous 150 psi pressure at 113 °F?

The coupling is rated for a maximum operating pressure of 150 psi within a temperature range of 32 °F to 113 °F.
