Description

Schedule 40 PVC Bushing (SPIG x SOC)

Schedule 40 PVC Reducer Bushings provide a compact transition between different pipe sizes in compatible cold-water pressure piping systems.

Featuring one spigot connection and one socket connection, this fitting is designed to reduce from a larger fitting size to a smaller Schedule 40 PVC pipe size. The spigot end installs directly into a compatible socket fitting, while the socket end accepts compatible PVC pipe, helping simplify size transitions in potable water, irrigation, pool, spa, and other compatible pressure applications.

Connection Configuration

Spigot End

The spigot end is designed to fit directly into a compatible Schedule 40 PVC socket fitting for a compact solvent-weld connection.

Socket End

The socket end accepts compatible Schedule 40 PVC pipe at the reduced nominal size.

Construction Details

The bushing is manufactured from high-quality Schedule 40 PVC for resistance to corrosion, chemical exposure, scaling, and environmental conditions commonly encountered in compatible cold-water pressure systems.

The spigot x socket design allows the fitting to install directly into a larger socket while accepting a smaller PVC pipe, creating a compact size transition without requiring a full reducing coupling.

Its smooth internal transition helps support efficient flow while maintaining compatibility with standard Schedule 40 PVC solvent-weld piping systems.

Why Choose a Reducer Bushing?

Compact Size Transition

  • Reduces between different nominal pipe sizes
  • Spigot installs directly into a compatible fitting
  • Socket accepts the smaller PVC pipe size
  • Can reduce the number of separate fittings required
  • Useful where installation space is limited

PVC Pressure-Piping Benefits

  • Corrosion-resistant construction
  • Lightweight material
  • Smooth internal flow path
  • Low maintenance requirements
  • Suitable for compatible cold-water applications

Typical Applications

Water & Irrigation Systems

  • Potable water distribution
  • Residential cold-water piping
  • Irrigation systems
  • Pipe-size transitions
  • Landscape watering systems

Pool, Spa & Commercial Systems

  • Swimming pool plumbing
  • Spa circulation systems
  • Commercial cold-water piping
  • Equipment piping transitions
  • General Schedule 40 PVC pressure systems

Solvent-Weld Installation

Verify both nominal connection sizes before installation. Confirm that the spigot size matches the receiving socket fitting and that the socket size matches the intended Schedule 40 PVC pipe.

Clean and prepare all mating PVC surfaces according to accepted solvent-weld procedures. Apply compatible PVC primer and solvent cement where required, then fully seat the spigot end into the mating socket fitting and the pipe into the bushing socket.

Confirm the fitting orientation before the solvent cement begins to set. Allow completed joints to cure according to the cement manufacturer's recommendations before pressurizing or placing the system into normal service.

Frequently Asked Questions

What is a Schedule 40 PVC reducer bushing used for?

It is used to reduce from a larger PVC fitting connection to a smaller compatible Schedule 40 PVC pipe size.

What does SPIG mean?

SPIG means spigot. The spigot end is designed to fit directly into a compatible socket fitting.

What does SOC mean?

SOC means socket. The socket end accepts compatible Schedule 40 PVC pipe.

How is a bushing different from a reducing coupling?

A reducer bushing fits directly into another socket fitting, while a reducing coupling typically has two socket ends and joins two pipe sections directly.

How is this fitting installed?

The spigot end is solvent welded into a compatible socket fitting, while the socket end is solvent welded to compatible Schedule 40 PVC pipe.

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 plumbing are among the listed 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 both nominal sizes, the Spigot x Socket configuration, the receiving socket fitting size, the reduced pipe size, and compatibility with the intended Schedule 40 PVC pressure system.
