Macomb Group Approved CC05200 Reducer Bushing 3/4x1/2 Sch 80

Product Description

The MACOMB GROUP APPROVED CC05200 is a Schedule 80 polypropylene flush reducer bushing designed for threaded pipe systems carrying corrosive or high-purity fluids. It transitions from a 3/4-inch male NPT connection down to a 1/2-inch female NPT connection, making it a compact fitting for reducing pipe diameter within a run. Molded from polypropylene meeting ASTM D4101, the bushing is rated for service up to 180 degrees F and conforms to ANSI B1.20.1 thread standards. It measures 1.27 inches in total length with an unthreaded length of 0.43 inches. Plumbers, pipefitters, and industrial service techs install this fitting in chemical, water treatment, pool, and process piping applications where black Schedule 80 thermoplastic fittings are specified.

This bushing is suited for residential and commercial piping systems where a reduction from 3/4-inch to 1/2-inch pipe is required in a corrosion-resistant thermoplastic material. The MNPT x FNPT configuration allows direct thread engagement into an existing female-threaded fitting or valve body, then accepts a 1/2-inch male-threaded pipe or fitting on the outlet side. Typical applications include pool and spa chemical feed lines, water treatment manifolds, and industrial process piping where polypropylene is preferred over metal fittings due to chemical compatibility requirements.

Key Features

• Schedule 80 wall thickness for elevated pressure ratings in thermoplastic piping systems
• Polypropylene construction conforming to ASTM D4101 for chemical and corrosion resistance
• MNPT x FNPT thread configuration per ANSI B1.20.1 for reliable thread engagement
• Rated to 180 degrees F for use in heated process and pool system piping
• Molded black finish for UV resistance and visual identification as Schedule 80 material
• Compact 1.27-inch length minimizes space requirements in tight pipe runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch to 1/2-inch MNPT x FNPT Schedule 80 thermoplastic piping systems, consistent with Chemtrol Series Model 6118-3-4 flush reducer bushing specifications.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Shut off all flow and depressurize the line before threading this bushing into or out of the system. Use PTFE thread tape or a thread sealant compatible with polypropylene and the media being conveyed. Do not over-torque threaded polypropylene fittings, as thermoplastic threads can crack under excessive wrench force.
