Anderson Metals 730561-10 Cts Insert Stiffener

Product Description

The ANDERSON METALS 730561-10 is a copper tube size (CTS) insert stiffener designed to reinforce the end of soft copper or plastic tubing inside a compression fitting. Machined from lead free brass, it fits inside the tube to prevent collapse when the compression nut and ferrule are tightened. At a maximum working pressure of 1500 psi, this insert stiffener maintains joint integrity in potable water, gas, and fluid distribution lines. Licensed plumbers and pipefitters install this component as standard practice when making compression connections on flexible or thin-wall tubing.

This insert stiffener is used in residential and light commercial plumbing applications wherever CTS compression fittings are employed. It is appropriate for use in water supply lines, fixture connections, and other fluid handling assemblies. The tube by NPT end configuration allows integration with threaded pipe systems while maintaining a reliable compression seal at the tubing end. Its compact size makes it suitable for tight spaces common in under-sink and in-wall rough-in work.

Key Features

• Lead free brass construction meets potable water contact requirements
• Rated to 1500 psi maximum working pressure
• CTS sizing ensures correct fit inside standard copper tube size compression fittings
• Tube x NPT end connections support integration with threaded pipe assemblies
• Prevents tubing collapse under compression ferrule load

Compatibility

Designed as an OEM-style replacement and standard-use insert stiffener for CTS compression fittings used in residential and light commercial plumbing systems.

Installation Notes

A licensed plumber should shut off the water supply and relieve system pressure before disassembling any compression fitting. Insert the stiffener fully into the tube end before sliding on the compression nut and ferrule. Do not overtighten the compression nut, as excess torque can deform the ferrule or tube. Work should comply with applicable local plumbing codes and IPC standards.
