Pro-source 90341000309 Cpvc Male Adapter 1-1/4 in Sch 80

Product Description

The PRO-SOURCE 90341000309 is a Schedule 80 CPVC male adapter designed to transition between male iron pipe thread (MIPT) and slip socket connections in plastic piping systems. Rated for Schedule 80 service, this fitting handles higher-pressure and higher-temperature applications than standard Schedule 40 fittings, making it well suited for hot and cold water distribution, chemical handling lines, and industrial process piping. At 1-1/4 inches, it fits a common trunk-line and branch-line size found in commercial and light industrial installations. Licensed plumbers and pipefitters are the primary installers, though experienced mechanical contractors also work with CPVC fittings in process applications.

This male adapter is used in CPVC piping systems where a threaded connection to a valve, pump, equipment port, or metal fitting is required on one end, with a solvent-weld slip socket on the other. Typical applications include commercial plumbing systems, industrial fluid handling, and mechanical rooms where Schedule 80 pressure ratings are specified. The 1-1/4-inch size is a standard transition fitting used at equipment connections, headers, and service points throughout a system.

Key Features

• Schedule 80 wall thickness for increased pressure and temperature capability compared to Schedule 40
• MIPT x Slip end connections allow threaded attachment on one side and solvent-weld socket on the other
• CPVC material provides corrosion resistance and compatibility with hot water and many chemical fluids
• 1-1/4-inch fitting size suits trunk lines, equipment inlets, and branch connections
• Lightweight construction at 0.42 pounds reduces handling fatigue during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 CPVC piping systems using 1-1/4-inch MIPT x slip connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the piping system completely before cutting into any line or removing existing fittings. Use only CPVC-rated solvent cement and primer on the slip socket end, following the cement manufacturer's cure time before pressurizing. Apply thread sealant or PTFE tape rated for CPVC compatibility on the MIPT connection to prevent leaks.
