Dura Plastic PVC80ADSFIP4 Schedule 80 Male Adapter 4 in

Product Description

The DURA PLASTIC PVC80ADSFIP4 is a 4-inch PVC Schedule 80 male adapter fitting designed to transition between a socket (spear) end and a female iron pipe thread (FIPT) connection. Built from rigid PVC to Schedule 80 pressure ratings, this adapter handles higher-pressure applications where standard Schedule 40 fittings fall short. It is installed by plumbers, pipefitters, and irrigation contractors working on industrial, commercial, and heavy-duty residential piping systems. The socket end accepts solvent cement bonding to a 4-inch PVC pipe, while the male threaded end connects to a female-threaded valve, pump port, or fitting.

This adapter is suited for cold and ambient-temperature water systems, chemical lines, and irrigation mains where Schedule 80 PVC is the specified pressure class. The 4-inch size makes it a common choice for main distribution lines, pump stations, pool and spa equipment pad plumbing, and industrial process piping. Licensed plumbers and pipefitters typically install this fitting where a system transitions from a solvent-welded PVC run to a threaded port on equipment or a valve body.

Key Features

• Schedule 80 PVC construction for higher pressure ratings compared to Schedule 40
• Socket (spear) inlet end for solvent-cement bonding to 4-inch PVC pipe
• Male iron pipe thread (MIPT) outlet for connection to female-threaded valves, pumps, or fittings
• Rigid PVC material provides resistance to corrosion and many common chemicals
• 4-inch nominal size suits main distribution and equipment pad applications

Compatibility

Designed as an OEM-style replacement and standard fitting for 4-inch PVC Schedule 80 piping systems using solvent-cement socket connections and female iron pipe thread ports.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC or local authority requirements. Depressurize and drain the system completely before cutting into any existing line. Apply an approved PVC primer and Schedule 80-rated solvent cement to the socket end per the cement manufacturer's instructions, and allow full cure time before pressurizing. Do not use heat to bend or modify this fitting, and do not overtighten the threaded connection, as PVC threads can crack under excessive torque.
