Allpoints 21612 Female Coupler 3/4 Inch Fnpt

Product Description

The ALLPOINTS 21612 is a 3/4-inch female coupler with female national pipe thread (FNPT) connections. This fitting creates a secure, leak-resistant joint between two threaded pipe sections in fluid-handling systems. It is a standard plumbing component used to join or extend pipe runs and is installed by licensed plumbers, pipefitters, and experienced mechanical contractors. At 1.3 pounds, the coupler is compact and straightforward to handle during installation in tight mechanical spaces.

This female coupler is suited for residential and light commercial plumbing applications where a 3/4-inch FNPT threaded connection is required. Typical install scenarios include water supply lines, hydronic heating systems, and general fluid distribution piping. The FNPT thread pattern is a widely used standard, making this coupler broadly compatible with schedule-rated pipe and standard threaded fittings found on most job sites.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Always shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply an approved thread sealant tape or compound to the male threads before making up the joint. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
