Connection Configuration
First Socket
The first socket accepts compatible Schedule 40 PVC pipe and forms one side of the straight coupling connection.
Second Socket
The opposite socket accepts a second section of compatible Schedule 40 PVC pipe to continue the piping run.
Construction Details
The coupling is manufactured from high-quality Schedule 40 PVC for resistance to corrosion, chemical exposure, and environmental conditions commonly encountered in compatible cold-water piping systems.
Both socket connections are designed for solvent-cement joining to compatible Schedule 40 PVC pipe, creating secure and leak-resistant permanent joints when properly installed.
The straight-through internal passage helps maintain efficient flow while allowing two pipe sections of the same nominal size to be joined into one continuous run.
Why Choose a Schedule 40 PVC Coupling?
Simple Straight Connection

Solvent-Weld Installation
Verify the nominal size of both socket connections before installation. Cut compatible Schedule 40 PVC pipe square and remove burrs from each pipe end.
Clean and prepare all mating surfaces according to accepted PVC solvent-weld procedures. Apply compatible PVC primer and solvent cement where required, then fully seat each pipe into the appropriate socket.
Make sure the two pipe sections remain properly aligned while the solvent cement begins to set. Allow completed joints to cure according to the cement manufacturer's recommendations before pressurizing or placing the piping system into normal service.

Our plumbing specialists can help review your pipe size, pressure-piping application, and solvent-weld installation requirements before you order.

What is a Schedule 40 PVC coupling used for?
It is used to join two sections of compatible Schedule 40 PVC pipe in a straight pressure piping run.
What does SOC x SOC mean?
It means both openings are socket connections designed to accept compatible Schedule 40 PVC pipe.
How is this coupling installed?
Both socket connections are installed using compatible PVC solvent-weld procedures.
Does this coupling change pipe size?
No. A standard coupling typically joins two sections of pipe of the same nominal size. A reducing coupling would be used where a size transition is required.
Can this fitting be used for potable water?
The supplied product information identifies this fitting for potable water applications and references NSF/ANSI 61 among its applicable standards.
Can it be used in irrigation systems?
Yes. Irrigation is one of the stated applications for this Schedule 40 PVC fitting.
Can it be used for pool and spa plumbing?
Yes. Pool and spa systems are among the listed applications.
Is this a pressure fitting?
Yes. This Schedule 40 PVC coupling is intended for compatible cold-water pressure piping applications.
What standards are referenced for this fitting?
The supplied product information references ASTM D2466, ASTM D1784, CSA B137.3, NSF/ANSI 14, NSF/ANSI 61, cNSF, and cUPC.
What should I verify before ordering?
Confirm the nominal pipe size, Socket x Socket configuration, operating requirements, and compatibility with the intended Schedule 40 PVC pressure piping system.
