Pro-source 90380300809 Pvc Coupling 4 in Sch 80 Slip X Slip

Product Description

The PRO-SOURCE 90380300809 is a 4-inch Schedule 80 PVC pipe coupling designed for joining two sections of same-diameter PVC pipe in pressure and drain applications. Built from rigid PVC with slip x slip end connections, this coupling accepts solvent-welded joints on both ends for a reliable, leak-free connection. At 2.22 pounds, it is sized for use in industrial, commercial, and heavy-duty plumbing systems where Schedule 80 wall thickness is required. Licensed plumbers and pipefitters are the typical installers, though experienced mechanical contractors work with this fitting in process piping and water treatment applications as well.

This coupling is suited for 4-inch Schedule 80 PVC piping systems found in industrial process lines, chemical handling, irrigation mainlines, and commercial plumbing installations. The slip x slip configuration requires solvent cement on both socket ends, making it appropriate for permanent, non-threaded connections. It is commonly installed in above-ground and below-ground pressure piping where Schedule 80 PVC is specified for added wall strength over Schedule 40.

Key Features

• 4-inch fitting size compatible with Schedule 80 PVC pipe outside diameter
• Schedule 80 wall construction provides greater pressure rating and impact resistance than Schedule 40
• Slip x slip end connections accept solvent-cement bonding on both sockets
• Rigid PVC material offers corrosion resistance in chemical and water service
• Weighs 2.22 pounds — suitable for overhead or in-line installation with standard PVC supports

Compatibility

Designed as an OEM-style replacement and standard fitting for 4-inch Schedule 80 PVC piping systems using slip-style solvent-weld connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC or local plumbing code requirements. Shut off and depressurize the piping system completely before cutting into the line. Use a PVC pipe cutter or fine-tooth saw, deburr pipe ends, and apply a compatible Schedule 80 PVC primer and solvent cement to both the pipe ends and coupling sockets before joining. Allow full cure time per the cement manufacturer instructions before returning the system to service.
