Pro-source 90340300809 Cpvc Pipe Coupling 4 in Sch 80

Product Description

The PRO-SOURCE 90340300809 is a 4-inch Schedule 80 CPVC pipe coupling designed for joining same-diameter pipe sections in pressurized fluid systems. Built from chlorinated polyvinyl chloride (CPVC), this coupling handles higher operating temperatures and pressures than standard PVC fittings, making it a reliable choice in industrial, commercial, and mechanical piping applications. The slip-by-slip end connections accept solvent-cement joining on both ends. Weighing 2.32 pounds, it is a solid, full-bodied fitting suited for permanent installations where Schedule 80 wall thickness is specified.

This coupling is used in applications where Schedule 80 CPVC piping is required, including hot and cold water distribution, chemical processing lines, and industrial fluid handling systems. It is a common replacement or addition fitting in plant maintenance, commercial plumbing, and process piping projects. Licensed plumbers and pipefitters typically install this fitting in systems that demand the corrosion resistance and temperature tolerance that CPVC provides over standard thermoplastic options.

Key Features

• 4-inch fitting size for full-bore flow continuity through the coupling
• Schedule 80 wall thickness provides greater pressure rating than Schedule 40
• CPVC material resists corrosion, chemical attack, and elevated fluid temperatures
• Slip x Slip end connections accept standard solvent-cement bonding on both ends
• Weighs 2.32 pounds — substantial construction consistent with Schedule 80 specifications

Compatibility

Designed as an OEM-style replacement and standard fitting for Schedule 80 CPVC piping systems using 4-inch nominal pipe diameter.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and ASTM standards for CPVC solvent-cement joints. Shut off system flow and depressurize the line completely before cutting and fitting. Use only CPVC-compatible primer and solvent cement — do not substitute PVC cement. Allow full cure time per cement manufacturer instructions before restoring system pressure.
