Diversitech 457-007 Pvc Sch 40 Socket Union 3/4 Inch

Product Description

The DIVERSITECH 457-007 is a 3/4-inch PVC Schedule 40 socket union with a Buna-N O-ring seal, designed for use in condensate drain and plumbing applications common to HVAC and related mechanical systems. This white PVC union allows technicians to create a serviceable connection point in a run of Schedule 40 PVC pipe, making it straightforward to disconnect and reconnect sections without cutting. The Buna-N O-ring provides a reliable, chemical-resistant seal at the union joint. This fitting is installed by HVAC technicians and plumbers working on drain lines, equipment connections, and similar low-pressure piping systems.

This union is suited for residential and light commercial applications where 3/4-inch Schedule 40 PVC piping is used. Typical installation scenarios include condensate drain lines on air handlers, fan coils, and other HVAC equipment, as well as general plumbing drain and vent assemblies where a break-apart connection is required for future serviceability.

Compatibility

Designed as an OEM-style replacement fitting for 3/4-inch Schedule 40 PVC piping systems commonly found in residential and light commercial HVAC condensate and plumbing drain applications.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians. Shut down the associated HVAC equipment or isolate the plumbing section before beginning work. Solvent-weld the socket ends to the pipe using PVC primer and cement appropriate for Schedule 40 fittings, following local plumbing codes such as the IPC. Hand-tighten the union nut first to seat the O-ring, then snug as needed — do not over-tighten, as PVC threads can crack under excessive force.
