Dura Plastic 457-030 Pvc Union 3 Inch Socket Sch 40

Product Description

The DURA PLASTIC 457-030 is a 3-inch Schedule 40 PVC union designed for socket-connect installations in residential and light commercial piping systems. This union allows sections of PVC pipe to be joined and separated without cutting, making it a standard component in systems that require periodic service or equipment removal. The body is manufactured from PVC for chemical resistance and durability, and the sealing interface uses a Buna-N O-ring to maintain a reliable, leak-free connection. This fitting is domestically produced and conforms to SCH 40 standard wall dimensions.

This union is suited for use in plumbing, irrigation, pool and spa, and industrial process piping where a removable joint is needed in a 3-inch line. The socket connection style accepts standard Schedule 40 PVC pipe ends and is bonded with solvent cement during installation. Plumbers, pool service technicians, and pipefitters commonly install this type of fitting when serviceability of downstream equipment is a design requirement.

Compatibility

Designed as an OEM-style replacement or new-install fitting for 3-inch Schedule 40 PVC piping systems using socket-connect configuration.

Installation Notes

Installation is performed by licensed plumbers or qualified pipe technicians. Depressurize and drain the line completely before cutting out an existing fitting or installing in a new run. Socket ends are joined using approved PVC primer and solvent cement per the pipe manufacturer instructions and applicable plumbing code. Tighten the union nut by hand to the point of firm resistance and avoid using pipe wrenches directly on the PVC body to prevent stress cracking.
