Anderson Metals 730261-08 Self-aligning Nut Captive Sleeve Npt

Product Description

The ANDERSON METALS 730261-08 is a compression tube self-aligning nut with captive sleeve, designed for secure, leak-resistant tube connections in plumbing and fluid-handling systems. Constructed from lead free brass, this fitting features an 11/16-20 NPT straight thread and is rated for a maximum working pressure of 750 psi. The self-aligning design allows the sleeve to seat correctly even when minor angular misalignment is present during makeup, reducing the risk of leaks caused by improper seating. Licensed plumbers and pipefitters install this type of fitting in potable water, gas, and mechanical service lines where a reliable compression joint is required.

This fitting is suited for residential and light commercial plumbing installations where compression-style tube connections terminate at NPT-threaded ports. Typical applications include water supply lines, refrigeration tubing connections, and hydraulic or pneumatic systems operating within the rated pressure range. The captive sleeve stays in place on the nut during assembly, simplifying one-handed installation in tight spaces or overhead runs.

Key Features

• Lead free brass construction meets potable water contact requirements
• Self-aligning captive sleeve reduces misalignment errors during makeup
• 11/16-20 NPT straight thread for compatibility with standard NPT ports
• Rated to 750 psi maximum working pressure
• Captive sleeve remains on nut for easier single-hand assembly

Compatibility

Designed as an OEM-style replacement or new-installation compression fitting for systems with 11/16-20 NPT-threaded ports requiring a self-aligning nut and captive sleeve assembly.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the system completely before disassembling or installing any compression fitting. Hand-tighten the nut to seat the sleeve, then follow standard practice for compression fitting makeup without over-torquing, which can deform the sleeve and cause leaks. Verify the completed joint is leak-free under system pressure before returning the system to service.
