Spears 839-167c Flush Reducing Bushing 1-1/4x3/4 Sch 80 Cpvc

Product Description

The SPEARS 839-167c is a flush reducing bushing designed to transition between a 1-1/4 inch male NPT thread and a 3/4 inch female NPT thread in a single molded fitting. Manufactured from CPVC and rated to Schedule 80/XH wall thickness, it is built for higher-pressure and higher-temperature service than standard Schedule 40 fittings. At 1-9/32 inches in length, this flush-style bushing sits flat within the fitting socket rather than protruding, keeping installed assemblies compact. It is installed by licensed plumbers and pipefitters in systems where chemical resistance, heat tolerance, and pressure rating are primary concerns.

This bushing is well suited for industrial process piping, chemical distribution lines, and hot-water plumbing systems where CPVC is specified for its resistance to corrosive fluids and elevated temperatures. The flush configuration makes it a practical choice in tight spaces or where a low-profile transition is required. Domestic manufacture supports traceability requirements common in commercial and industrial project specifications.

Key Features

• Flush bushing profile keeps the fitting compact and low-profile within the assembly
• Schedule 80/XH wall thickness provides higher pressure and impact resistance compared to Schedule 40
• CPVC construction offers chemical resistance and elevated temperature performance
• MNPT x FNPT thread configuration for threaded pipe system integration
• Molded one-piece construction with no joints or seams at the transition point
• Domestically manufactured to support project traceability requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 CPVC threaded piping systems requiring a 1-1/4 inch to 3/4 inch reducing bushing transition.

Installation Notes

Installation should be performed by a licensed plumber familiar with CPVC threaded fitting assemblies. Shut off system pressure and drain the line before removing or installing any threaded fitting. Use CPVC-compatible thread sealant or PTFE tape rated for use with plastic fittings — avoid over-tightening, as CPVC threads can crack under excessive torque. Consult applicable plumbing codes, including IPC requirements, for approved use of CPVC in the intended service environment.
