Spears 4137-130 1" x 1/2" CPVC CTS Red Reducer Bushing, Spigot x Socket

Spears 4137-130 1" x 1/2" CPVC CTS Red Reducer Bushing, Spigot x Socket

The Spears 4137-130 is a 1" x 1/2" CPVC CTS reducer bushing engineered to transition between two different pipe diameters within a CTS (copper tube size) piping system. Molded from red CPVC for easy visual system identification, this fitting features a spigot x socket connection that allows it to slip into an existing socket fitting while accepting a smaller pipe on the opposite end. Because it uses a bushing profile rather than a full-body reducer coupling, the 4137-130 is well suited to tight spaces where a standard reducer will not fit. Like other Spears CPVC CTS fittings, it is designed to be solvent-welded for a permanent, leak-resistant joint that meets the demands of professional piping installations.

Key Features

• Trade Size: 1" x 1/2" reducer bushing for stepping down from a larger CTS pipe run to a smaller branch line.
• Durable Construction: CPVC CTS material offers corrosion and chemical resistance for demanding piping applications.
• Connection Type: Spigot x socket ends allow the fitting to be solvent-welded directly into a mating socket fitting on one end and onto a smaller pipe on the other.
• Color-Coded Red: Molded in red CPVC for quick visual identification within a piping system.
• Compact Reducer Profile: Bushing-style design slips inside an existing socket fitting when a full-body reducer coupling will not fit the available space.
• CTS Sizing: Copper tube size (CTS) dimensioning ensures compatibility with other CTS-based CPVC components in the system.
