Spears 54211168950 Cpvc Adapter 3/4 in Socket X Fnpt Sch 80

Product Description

The SPEARS 54211168950 is a 3/4 inch Schedule 80 CPVC standard adapter designed to transition between socket and female NPT threaded connections in pressure piping systems. Molded from CPVC, this adapter handles the elevated temperatures and corrosive fluid exposures common in industrial and commercial plumbing lines. The socket end accepts solvent-welded pipe while the FNPT end threads directly onto male-threaded fittings or valves. At 1-27/32 inches in length, it is a compact fitting suited for tight installations. Licensed plumbers and pipefitters install this type of adapter when connecting CPVC pipe runs to threaded metal or plastic components within a system.

This adapter is used in pressure piping applications where a solvent-weld CPVC socket connection must transition to a female NPT threaded port. Typical installations include chemical handling lines, hot and cold water distribution systems, and industrial process piping where CPVC is specified for corrosion resistance. The SCH 80 wall thickness provides additional pressure capacity compared to Schedule 40 fittings, making it appropriate for higher-pressure service runs in both residential and light commercial settings.

Key Features

• 3/4 inch nominal size with socket x FNPT end configuration for socket-to-thread transitions
• Schedule 80 / XH wall rating for increased pressure capacity
• Molded CPVC construction for corrosion resistance and elevated temperature tolerance
• Compact 1-27/32 inch length suits space-constrained installations
• Gray color standard for Schedule 80 CPVC pressure fittings
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 CPVC pressure piping systems using 3/4 inch nominal pipe with socket-to-female-NPT connection requirements.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes, including IPC and local jurisdictional requirements. Depressurize and drain the piping system fully before cutting into any line or removing existing fittings. The socket end requires proper CPVC solvent cement and primer applied per the cement manufacturer's instructions and allowed to cure before returning the system to service. Do not overtighten the FNPT threaded connection, as CPVC threads can crack under excessive torque.
