Homewerks 512-44-12-12B 1/2 in Pvc Threaded Union Sch 80

Product Description

The HOMEWERKS WORLDWIDE LLC 512-44-12-12B is a 1/2 inch gray PVC threaded union built to Schedule 80 heavy-duty standards. It joins threaded PVC pipe runs and allows for easy disconnection without cutting pipe, making it a reliable service fitting in pressurized water and chemical systems. The union seals with a rubber O-ring for a leak-resistant joint and is rated at 150 psi at 73 degrees F. Plumbers and pipefitters install this fitting in both residential and light commercial applications where PVC is the specified material. It complies with ANSI B2.1 thread standards, confirming dimensional compatibility with standard NPT fittings.

This union is suited for use in water distribution, irrigation, pool and spa plumbing, and industrial piping systems where PVC is permitted. Its Schedule 80 construction provides greater wall thickness and pressure tolerance than Schedule 40, but it is designed to work with either Schedule 80 or Schedule 40 PVC pipe, giving installers flexibility when working in mixed-schedule systems. Typical applications include pump isolation, filter connections, and any run where future serviceability is required without cutting out the fitting.

Compatibility

Designed for use with 1/2 inch Schedule 80 or Schedule 40 PVC threaded pipe. Compatible with standard NPT-threaded PVC fittings and components meeting ANSI B2.1 specifications.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off system pressure and drain the line before removing or installing union fittings. Apply PTFE thread tape or an appropriate thread sealant to NPT threads before assembly and hand-tighten followed by wrench tightening — avoid overtightening PVC threads, as this can crack the fitting body. Verify that the O-ring is properly seated in the union nut before final assembly.
