Nibco px80540a Pex Reducing Coupling 3/4x1/2 F1807

Product Description

The NIBCO px80540a is a lead-free PEX reducing coupling manufactured to ASTM F1807 standards, designed to connect 3/4-inch PEX tubing to 1/2-inch PEX tubing using a swivel sleeve clamp (SSC) connection method on both ends. This fitting is used to reduce line size within a PEX distribution system, allowing plumbers to transition between supply mains and branch lines without added fittings or adapters. The F1807 standard ensures dimensional consistency and material quality for use in potable water and hydronic heating applications. Its lead-free construction meets current NSF and plumbing code requirements for drinking water systems.

This reducing coupling is suited for residential and light commercial plumbing installations where PEX tubing is used for hot and cold water distribution. It is a direct in-line fitting installed mid-run to step down from a 3/4-inch main to a 1/2-inch branch or tail-off line. Licensed plumbers and pipefitters working with PEX swivel sleeve clamp tooling will find this fitting compatible with standard SSC crimp or clamp installation workflows.

Key Features

• Reduces 3/4-inch PEX to 1/2-inch PEX in a single in-line fitting
• Swivel sleeve clamp (SSC) connection on both ends per ASTM F1807
• Lead-free construction for use in potable water systems
• Meets applicable plumbing code requirements for drinking water contact
• Consistent dimensional tolerances for reliable clamp engagement

Compatibility

Designed as an OEM-style replacement and standard-use fitting for ASTM F1807 PEX swivel sleeve clamp systems using 3/4-inch and 1/2-inch PEX tubing.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before cutting into an existing line. Use the appropriate SSC clamp tool sized for each end of the fitting to ensure a full, even clamp engagement. Do not over-drive clamps or use incompatible crimp tooling, as improper installation can result in leaks at the fitting interface.
