Spears 54211179086 Flush Reducing Bushing 1-1/4x1/2 Sch 80 Cpvc

Product Description

The SPEARS 54211179086 is a flush reducing bushing designed for pressure piping systems where a larger male-threaded connection must transition down to a smaller female-threaded port. Manufactured from CPVC and rated Schedule 80/XH, this bushing handles the elevated pressures and temperatures common in industrial and commercial plumbing and chemical handling lines. The molded construction provides consistent wall thickness and thread integrity. At 1-5/16 inches in length, the flush profile keeps the fitting compact within tight assemblies. Licensed plumbers and pipefitters install this type of fitting when reducing line size within a threaded system without adding unnecessary extension to the run.

This bushing is suited for residential and commercial pressure piping applications where CPVC is specified for corrosion resistance or elevated temperature service. Typical installation scenarios include chemical distribution lines, hot and cold water systems, and industrial process piping. The MNPT x FNPT configuration allows it to thread directly into a female-threaded fitting or valve body while accepting a smaller male-threaded pipe or fitting on the outlet side. It is manufactured domestically.

Key Features

• CPVC material provides excellent corrosion resistance and higher temperature tolerance compared to standard PVC
• Schedule 80/XH wall thickness rated for pressure service in demanding piping systems
• Flush bushing profile keeps the assembled fitting compact in tight spaces
• MNPT x FNPT end configuration enables direct threaded installation without additional adapters
• Molded construction ensures consistent dimensions and reliable thread engagement
• Domestically manufactured gray CPVC fitting

Compatibility

Designed as an OEM-style replacement or new-installation reducing bushing for Schedule 80 CPVC threaded pressure piping systems with a 1-1/4 inch to 1/2 inch reduction requirement.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded CPVC pressure systems. Depressurize and drain the line fully before removing or installing any threaded fittings. Apply a CPVC-compatible thread sealant or tape to the male threads before assembly and tighten by hand first, then wrench-tighten only enough to achieve a leak-free seal — over-tightening threaded plastic fittings can crack the socket. Follow applicable IPC and local plumbing code requirements for CPVC pressure piping installations.
