Spears 4137-249 2" x 1" CPVC CTS Reducing Bushing, Spigot x Socket

Spears 4137-249 2" x 1" CPVC CTS Reducing Bushing, Spigot x Socket

The Spears 4137-249 is a 2" x 1" CPVC CTS reducing bushing designed to transition pipe runs from a larger 2" diameter line down to a smaller 1" diameter line within a single, compact fitting. Molded from CPVC (Chlorinated Polyvinyl Chloride) material and dimensioned to CTS (Copper Tube Size) standards, the 4137-249 features a spigot end that inserts directly into a matching CTS socket fitting and a socket end that accepts a smaller-diameter pipe for a solvent-cement joint. This Spigot x Socket configuration allows installers to reduce pipe diameter at a transition point without adding a separate coupling, simplifying layout and reducing the number of joints in a CPVC CTS piping run. This makes the 4137-249 well suited for plumbing and piping professionals who need to reduce pipe diameter cleanly at a transition point in a CPVC CTS system.

Key Features

• Trade Size: 2" x 1" reducing bushing, allowing a transition from 2" CTS pipe on one end to 1" CTS pipe on the other within a single fitting.
• Durable Construction: Molded from CPVC material, a rigid thermoplastic commonly specified for CTS piping systems that require chemical and temperature resistance beyond standard PVC.
• Connection Type: Spigot x Socket configuration — the 2" spigot end is sized to insert directly into a matching CTS socket fitting, while the 1" socket end accepts pipe for a solvent-cement (solvent-weld) joint.
• CTS Sizing: Manufactured to Copper Tube Size (CTS) dimensional standards, ensuring compatibility with other CPVC CTS fittings and pipe in the same piping system.
• Compact Reducer Design: A single-piece bushing reduces pipe diameter at a transition point, eliminating the need for a separate reducing coupling and minimizing the number of joints in the run.
• Reducing Fitting: Purpose-built as a reducing bushing (not a straight coupling), the 4137-249 is intended specifically for stepping down from 2" to 1" CTS pipe.
