Sioux Chief 649WP2 Pex-a Expansion Sleeve 1/2 Inch F1960

Product Description

The SIOUX CHIEF 649WP2 is a 1/2-inch polyethylene expansion sleeve designed for use with F1960 PEX-A piping systems. This sleeve slides over the end of a PEX-A tube before the pipe is expanded and receives an expansion fitting, creating a strong, reliable connection as the tubing returns to its original diameter. The sleeve reinforces the expanded end of the tubing and helps maintain joint integrity over the life of the installation. Plumbers and pipefitters working with PEX-A systems rely on this sleeve as a standard component in every F1960 expansion joint assembly.

This sleeve is suited for residential and light commercial plumbing applications where F1960 PEX-A tubing is used for hot and cold water distribution. It is used in conjunction with an expansion tool and compatible F1960 brass or polymer expansion fittings. Each sleeve is sized specifically for 1/2-inch tubing, making it a go-to component in new construction and retrofit plumbing projects where PEX-A is the pipe material of choice.

Key Features

• Sized for 1/2-inch F1960 PEX-A tubing
• Polyethylene construction compatible with PEX-A expansion systems
• Supports reliable joint formation as expanded tubing recovers around the fitting
• Designed to meet ASTM F1960 standard expansion connection requirements
• Compact sleeve form factor allows fast, repeatable installation on the job

Compatibility

Designed for use with 1/2-inch F1960 PEX-A tubing and compatible ASTM F1960 expansion fittings. Not intended for use with PEX-B or PEX-C crimp or clamp systems.

Installation Notes

Installation requires a calibrated PEX-A expansion tool sized for 1/2-inch tubing. Shut off the water supply and depressurize the line before making connections. Slide the sleeve onto the tubing before expanding the pipe end, then seat the expansion fitting fully before the tubing recovers. Follow local plumbing code requirements, including applicable sections of the IPC or UPC, for approved use of PEX-A expansion connections.
