The IPEX 36421 is a 3/4-inch PVC Schedule 80 Socket x Male Adapter designed for industrial and commercial piping systems where chemical resistance and pressure performance are required. This fitting connects a socket end to a male threaded end, allowing transition between socket-weld PVC pipe and threaded pipe or equipment connections. Schedule 80 wall thickness provides greater pressure ratings compared to Schedule 40, making it appropriate for demanding service conditions. Plumbers and pipefitters install this adapter in chemical processing lines, industrial fluid handling, and water treatment applications where corrosion resistance is a priority.
This adapter is suited for use in systems handling acids, alcohols, alkalis, salt solutions, and halogens. It performs well in both potable water systems and industrial process piping. The smooth interior bore resists scale and corrosion buildup, maintaining consistent flow over the service life of the system. It is listed with the National Sanitation Foundation (NSF) and CSA International for potable water use, making it applicable in a range of residential and commercial plumbing configurations as well as industrial installations.
Designed as an OEM-style Schedule 80 PVC fitting for use in industrial process piping, chemical handling systems, and potable water distribution lines requiring a 3/4-inch socket-to-male-thread transition.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASTM standards for PVC pressure piping. Shut off and depressurize the system completely before cutting into existing pipe or removing existing fittings. Use a PVC primer and solvent cement rated for Schedule 80 PVC on the socket end, and apply thread sealant compatible with PVC on the male threaded end. Do not use metal pipe wrenches directly on PVC fittings without protective wrapping, as overtightening can crack the fitting body.
