Ipex 36721 Pvc Sch 80 Reducing Coupling 1x3/4 in Sxs

Product Description

The IPEX 36721 is a Schedule 80 PVC reducing coupling with a 1 inch by 3/4 inch socket-by-socket (SxS) configuration. Designed for use in industrial and commercial piping systems, this fitting connects pipes of two different diameters using solvent-cement joints. Its Schedule 80 wall thickness provides greater pressure handling capability compared to Schedule 40, making it a reliable choice in systems where elevated pressures or mechanical stress are present. The PVC construction resists rust, pitting, scale, and corrosion, keeping interior walls smooth across a wide range of service conditions. Plumbers and pipefitters install this fitting in chemical process, industrial fluid handling, and potable water distribution applications.

This coupling suits residential, commercial, and light industrial piping installations where a threaded or socket reducing connection is needed between 1 inch and 3/4 inch PVC Schedule 80 pipe. The fitting is listed with the National Sanitation Foundation (NSF) and CSA International for use with potable water, making it appropriate for plumbing systems subject to drinking-water compliance requirements. It also performs well in systems handling acids, alcohols, salts, and halogens, fitting the IPEX Xirtec PVC system for complete pipe, valve, and fitting packages from a single manufacturer.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off and depressurize the piping system completely before cutting into any existing line. Use a manufacturer-approved PVC solvent cement and primer rated for Schedule 80 fittings; follow cure times before returning the system to service. Do not use this fitting with pipe schedules, materials, or solvent cements for which it is not rated.
