Spears 54211149645 Pvc Union 1/2 in Socket Sch 40

Product Description

The SPEARS 54211149645 is a 1/2-inch PVC union fitting designed for socket-end connections in Schedule 40 and Standard-weight piping systems. Molded from PVC Type I (cell classification 12454) and sealed with a Buna-N O-ring, it provides a reliable, removable joint in pressurized water lines. At 1-27/32 inches in length and 0.08 pounds, this compact union is suited for residential and light commercial plumbing installations where periodic disassembly and serviceability of piping runs is required. It is certified for potable water service by NSF International and conforms to ASTM D2466 and ASTM D1784, making it appropriate for code-compliant work.

This union fitting is used in Schedule 40 PVC piping systems for domestic water supply, irrigation, industrial fluid handling, and other low-to-moderate pressure plumbing applications. Its socket end style accepts standard 1/2-inch PVC pipe ends with solvent cement, and the Buna-N O-ring creates a leak-resistant seal at the union interface. Plumbers and pipefitters install this fitting where the piping layout demands a break-apart connection point for equipment service or future modifications. The white PVC construction is standard for potable water and general-purpose above-ground piping.

Compatibility

Designed as an OEM-style replacement and standard fitting for 1/2-inch Schedule 40 and Standard-weight PVC piping systems used in potable water and general plumbing applications.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and depressurize the piping system completely before cutting into any existing line. Socket ends require proper solvent cement and primer applied per ASTM D2564 procedures; allow full cure time before restoring pressure. Do not overtighten the union nut, as PVC threads and seating surfaces can crack under excessive mechanical force.
