Dura Plastic 457-012 Pvc Union 1-1/4 in Socket Sch 40

Product Description

The DURA PLASTIC 457-012 is a Schedule 40 PVC union fitting designed for 1-1/4 inch socket connections in pressure piping systems. This union allows plumbers and pipefitters to disconnect and reconnect pipe runs without cutting, making it a standard choice for service access points on pumps, valves, and equipment. Constructed from PVC with a Buna-N O-ring seat, it provides a reliable, chemically resistant seal suited for water, mild chemicals, and pool or irrigation system applications. Domestic manufacture ensures consistent dimensional compliance with ASTM standards for Schedule 40 fittings.

This union is appropriate for residential and light commercial plumbing, pool and spa equipment plumbing, irrigation systems, and chemical handling lines where PVC is a code-accepted material. The socket-style end connections are solvent-welded, and the union nut threads together to compress the Buna-N O-ring, creating a pressure-rated joint that can be broken for maintenance without disturbing the solvent-welded connections upstream or downstream.

Key Features

• Schedule 40 wall thickness meets ASTM dimensional standards for pressure-rated PVC fittings
• Buna-N O-ring provides a compression seal at the union joint face
• Socket ends accept solvent cement for permanent upstream and downstream connections
• PVC construction resists corrosion, chlorine, and a broad range of mild chemicals
• Domestically manufactured for consistent quality and dimensional accuracy

Compatibility

Designed as an OEM-style replacement or new-installation union for Schedule 40 PVC piping systems using 1-1/4 inch socket connections.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off system pressure and drain the line before disassembly or solvent welding. Follow solvent cement manufacturer cure times before pressurizing the system. Installations must comply with applicable local plumbing codes and ASTM D2466 standards for Schedule 40 PVC fittings.
