Dura Plastic PVC80COUP4 Pvc Sch 80 Socket Coupling 4 in

Product Description

The DURA PLASTIC PVC80COUP4 is a 4-inch Schedule 80 PVC socket coupling used to join two lengths of PVC pipe in a straight run. Built to Schedule 80 wall thickness standards, this fitting handles higher pressure ratings than standard Schedule 40 fittings, making it suitable for demanding industrial, commercial, and mechanical piping applications. The socket ends accept pipe via solvent-weld cement for a permanent, leak-resistant joint. Licensed plumbers and pipefitters are the primary installers of Schedule 80 PVC fittings in pressure piping systems.

This coupling is used in residential and commercial plumbing, industrial process piping, irrigation mainlines, and chemical distribution systems where Schedule 80 PVC is specified. The 4-inch size fits standard 4-inch Schedule 80 PVC pipe. It is commonly installed in horizontal and vertical runs wherever a straight pipe-to-pipe connection is needed without a change in direction or diameter.

Key Features

• Schedule 80 wall thickness for elevated pressure service compared to Schedule 40
• Socket (S x S) ends for solvent-weld connection on both sides
• 4-inch pipe size accommodates standard 4-inch Schedule 80 PVC pipe
• PVC construction offers corrosion resistance and chemical compatibility across a wide range of fluids
• Straight coupling design maintains pipe alignment in continuous runs

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch Schedule 80 PVC piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following IPC or applicable local plumbing code requirements. Before cutting into an existing line, shut off flow and depressurize the system completely. Clean and dry pipe ends before applying PVC primer and Schedule 80-rated solvent-weld cement per manufacturer instructions. Allow full cure time before restoring pressure to the line.
