Value Collection 857-040 Pvc Pipe Union 4 in Sch 80 Slip X Slip

Product Description

The VALUE COLLECTION 857-040 is a Schedule 80 PVC pipe union designed for 4-inch slip x slip connections in industrial and commercial piping systems. The union features a Viton O-ring seat for a reliable, leak-resistant seal where disassembly and reassembly are required during maintenance or system modifications. Schedule 80 PVC wall thickness provides greater pressure capacity than Schedule 40, making this fitting suitable for higher-demand fluid handling applications. Plumbers, pipefitters, and mechanical contractors install this fitting where threaded or flanged unions are not specified and solvent-weld slip connections are the standard method.

This union is appropriate for chemical process lines, water treatment systems, industrial fluid transfer, and irrigation manifolds where PVC piping is specified at Schedule 80. The slip x slip end connections accept 4-inch PVC pipe on both sides via solvent cement. The Viton O-ring provides chemical compatibility with a wider range of fluids compared to standard EPDM or Buna-N elastomers, making it a preferred choice in applications involving aggressive chemicals or solvents that would degrade other O-ring materials.

Key Features

• Schedule 80 PVC construction for higher pressure and impact resistance versus Schedule 40
• Viton O-ring seat provides superior chemical resistance compared to standard elastomers
• 4-inch slip x slip end connections accept solvent-cement installation
• Union design allows in-line disassembly without cutting pipe
• Suitable for chemical, water treatment, and industrial fluid handling systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch Schedule 80 PVC piping systems using slip-style solvent-weld connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Depressurize and drain the piping system completely before cutting into an existing line. Use the correct Schedule 80 PVC solvent cement and primer for slip connections; do not mix Schedule 40 and Schedule 80 cements. Allow full cure time per the cement manufacturer before returning the system to service.
