Anderson Metals Corp 710559-08 Compression Stiffener Sleeve

Product Description

The ANDERSON METALS CORP 710559-08 is a compression stiffener sleeve designed for use with 1/2 inch OD plastic tubing. This fitting provides internal support inside flexible plastic tubing at a compression fitting connection, preventing the tubing from collapsing under the compression nut and ferrule. Each package contains 2 sleeves. The product is lead free compliant and meets the requirements of Public Law 111-380, making it suitable for potable water applications where lead-free materials are required by code. Plumbers and pipefitters install this type of insert to ensure a reliable, leak-free compression joint on plastic supply lines.

This stiffener sleeve is used in residential and light commercial plumbing applications where flexible plastic tubing — such as polyethylene or PEX — connects to compression-style fittings. Typical install scenarios include under-sink supply lines, water supply risers, and similar low-pressure domestic water distribution connections. The sleeve is inserted into the end of the tubing before the compression nut and ferrule are assembled, reinforcing the tubing wall at the joint.

Installation Notes

Installation is performed by licensed plumbers following local plumbing codes and IPC guidelines. Shut off the water supply and relieve line pressure before disassembling any compression fitting. Insert the stiffener sleeve fully into the tubing end before sliding on the compression nut and ferrule. Do not overtighten compression nuts on plastic tubing, as this can crack the fitting body or deform the tubing.
