1-1/2 inch x 1-1/4 inch PVC Schedule 40 Reducing Bushing Male x Female

1-1/2 inch x 1-1/4 inch PVC Schedule 40 Reducing Bushing – Solvent Weld Fitting for Pipe Size Transitions

The 1-1/2 inch x 1-1/4 inch PVC Reducing Bushing is a molded Schedule 40 fitting designed to connect piping of two different diameters in low-pressure applications such as drain, waste, and vent (DWV) systems, as well as cold water distribution networks. Manufactured from rigid polyvinyl chloride (PVC) in accordance with ASTM D2466, it provides corrosion resistance and long-term dimensional stability under non-pressure or gravity-fed conditions.

This bushing features a spigot end sized to fit into a 1-1/2 inch socket and a socket interior to receive a 1-1/4 inch pipe, allowing for direct solvent-weld transitions while preserving system integrity and alignment.

Key Technical Features

• ✅ Material: PVC Type I (Cell Class 12454) per ASTM D1784 – suitable for non-metallic, cold water systems.
• ✅ Connection: Spigot x Socket – Designed for solvent cement welding into a larger fitting or pipe.
• ✅ Standard Compliance: Conforms to ASTM D2466 for Schedule 40 PVC fittings and dimensional tolerances.
• ✅ Application Use: Intended for use in gravity-fed DWV systems and low-pressure cold water lines up to 140°F (60°C).
• ✅ Non-Conductive and Corrosion-Resistant: Suitable for chemically aggressive environments where metallic fittings would degrade.

Specifications

• Nominal Sizes: 1-1/2 inch (spigot) x 1-1/4 inch (socket)
• Fitting Type: Reducing Bushing
• Material: Schedule 40 PVC
• Temperature Rating: Up to 140°F (when used in non-pressure systems)
• Certifications: Complies with NSF/ANSI 14 and applicable IPC/UPC requirements

Installation Notes

Ensure both mating surfaces are clean and dry before solvent welding. Use a compatible primer and Schedule 40-rated solvent cement per ASTM F656 and F493 standards. Insert and rotate pipe a quarter turn for full adhesion, then allow sufficient cure time before pressurization or mechanical stress. This fitting is not intended for threaded or pressurized applications.

Common Applications

Used in residential and commercial DWV systems where a reduction in line diameter is needed without introducing threaded components. Common in vertical stacks, fixture arms, and branch lines where compact transitions are required to meet dimensional or spatial constraints.

Compliance Information

This fitting is certified for use in potable water and DWV applications and is manufactured to meet U.S. plumbing codes governing non-metallic piping systems. Not intended for use in hot water systems or for transport of compressed gases.
