Nibco CC05400 Flush Reducer Bushing 1-1/4x1 in Sch 80

Product Description

The NIBCO CC05400 is a Schedule 80 flush reducer bushing designed to transition between 1-1/4-inch and 1-inch threaded pipe connections in industrial and commercial piping systems. Molded from black polypropylene, it offers solid resistance to corrosion and many common chemicals, making it a practical choice where metal fittings are not suitable. The MIPT x FIPT end configuration allows it to thread directly into female-threaded pipe or fittings while accepting a male-threaded connection on the other side. Licensed plumbers and pipefitters typically install this fitting in process piping, chemical handling lines, irrigation systems, and general fluid distribution applications.

This reducer bushing is suited for Schedule 80 plastic piping systems where a reduction from 1-1/4 inches to 1 inch is required. The flush-style design seats cleanly into a female port without protruding significantly beyond the fitting face, which is useful in tight installations or when spacing between fittings is limited. It is commonly found in commercial plumbing, light industrial process lines, and irrigation assemblies where polypropylene compatibility with the conveyed fluid is confirmed.

Key Features

• Schedule 80 wall thickness for higher pressure-rated applications compared to Schedule 40
• Polypropylene construction provides corrosion resistance and compatibility with many acids and bases
• Flush reducer bushing profile minimizes installed length for compact piping layouts
• MIPT x FIPT end connections allow direct integration into standard NPT-threaded systems
• Black color for UV-resistant outdoor or exposed installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene threaded piping systems using standard NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and ASTM or ASME piping standards. Depressurize and drain the system fully before removing or installing any threaded fittings. Use PTFE thread tape or an appropriate thread sealant rated for polypropylene and the conveyed fluid. Do not overtighten threaded polypropylene fittings, as the material can crack under excessive torque; hand-tighten plus a modest wrench turn is the general practice for plastic NPT fittings.
