Ipex 429040 Pvc Schedule 40 4 Inch Slip X Slip Coupling

Product Description

The IPEX 429040 is a Schedule 40 PVC straight coupling designed for joining 4-inch pipe sections in pressurized plumbing systems. Manufactured from rigid PVC conforming to ASTM D1784 and D2466, this fitting connects pipe-to-pipe using a slip x slip end connection sealed with a Buna-N O-ring. It carries a 140 degrees F temperature rating and meets NSF/ANSI 14 and 61G standards for safe use in potable water systems. The lead-free construction satisfies AB1953 compliance requirements. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications where a reliable, chemical-resistant joint is needed on 4-inch Schedule 40 PVC lines.

This coupling is suited for residential and light commercial drinking water distribution, irrigation mains, and general-purpose pressure plumbing where PVC Schedule 40 pipe is specified. The slip x slip socket design accepts standard 4-inch PVC pipe on both ends and is compatible with solvent-cement joining per standard plumbing practice. Its NSF/ANSI 61G listing makes it appropriate for potable water contact in municipal and private water service applications.
