Spears 437-166 1-1/4" x 1/2" PVC Schedule 40 Reducing Bushing, Spigot x Socket

Spears 437-166 1-1/4" x 1/2" PVC Schedule 40 Reducing Bushing, Spigot x Socket

The Spears 437-166 is a 1-1/4" x 1/2" PVC Schedule 40 reducing bushing engineered to transition pipe sizes within PVC pressure piping systems. Featuring a spigot x socket (SPGxSOC) connection configuration, this fitting lets installers step down from a 1-1/4" line to a 1/2" branch while maintaining a solvent-weld seal on both ends. Molded from PVC and built to Schedule 40 dimensional standards, the 437-166 reducing bushing delivers dependable, corrosion-resistant performance for plumbing, irrigation, and general-purpose piping work. This reducing bushing is commonly specified by plumbing and irrigation contractors who need to adapt larger PVC trunk lines down to smaller branch lines without switching to a full coupling and adapter combination.

Key Features

• Trade Size: 1-1/4" x 1/2" reducing configuration provides a clean, code-compliant transition between two different pipe diameters.
• Durable Construction: Molded from PVC for excellent corrosion and chemical resistance in pressurized piping systems.
• Spigot x Socket Connection: SPGxSOC ends allow the fitting to be solvent-welded directly into a socket fitting on one end and a socket pipe or fitting on the other for a secure, leak-resistant joint.
• Schedule 40 Rating: Manufactured to Schedule 40 dimensional standards for compatibility with standard PVC Schedule 40 pipe and fittings.
• Reducing Bushing Design: Simplifies size transitions without the need for multiple couplings, reducing joint count and potential leak points.
• Easy Installation: PVC construction and spigot x socket ends allow the 437-166 to be installed with standard PVC primer and solvent cement, integrating cleanly into existing Schedule 40 pipe runs.
