Dura Plastic 457-007 Pvc Union 3/4 Inch Slip Sch 40

Product Description

The DURA PLASTIC 457-007 is a 3/4-inch nominal PVC union fitting designed for slip-end connections in Schedule 40 standard-wall piping systems. It uses a Buna-N O-ring seal to create a reliable, leak-resistant joint that can be broken and remade without cutting pipe. Domestically manufactured, this union is built for pressurized water systems where serviceable connections are required. Licensed plumbers and pool service technicians rely on this type of fitting wherever equipment isolation or routine service access is needed.

This fitting is suited for residential and light commercial plumbing, irrigation, and pool or spa circulation systems that use Schedule 40 PVC piping. The slip end style accepts standard 3/4-inch PVC pipe with solvent-cement, making it compatible with conventional PVC installation practices. It is commonly installed at pump flanges, filter housings, and other equipment connection points that require periodic disconnection for maintenance.

• 3/4-inch nominal size with slip end style for solvent-cemented PVC pipe connections

Installation Notes
