Anderson Metals 750066-0806 Compression Connector 3/8 Npt

Product Description

The ANDERSON METALS 750066-0806 is a straight compression tube connector designed to join a compression-end tube to a female NPT (FNPT) threaded port. Manufactured from lead free brass, this connector delivers reliable sealing performance in fluid and gas distribution systems. It carries a maximum working pressure of 2000 psi, making it appropriate for demanding plumbing, refrigeration, and instrumentation applications. The fitting features a 3/8 inch NPT thread size with a straight thread dimension of 11/16-20 on the compression side. Licensed plumbers and pipefitters install this type of connector in both commercial and residential systems where a leak-free mechanical connection is required without soldering.

This connector is suited for residential and light commercial plumbing, HVAC refrigerant piping support lines, pneumatic control lines, and instrument tubing installations. The compression by FNPT end configuration allows a tube to be connected directly to any female NPT-threaded port or valve body. It is a common fitting used when a removable, re-serviceable connection is preferred over a brazed or soldered joint.

Key Features

• Lead free brass construction meets current plumbing code requirements for potable water systems
• 2000 psi maximum working pressure for high-demand applications
• 3/8 inch NPT thread standard for broad compatibility with standard pipe fittings
• Compression x FNPT end connections allow tool-accessible, re-serviceable joints
• Straight thread size of 11/16-20 on the compression end ensures positive tube grip
• Compact form factor supports installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8 inch NPT female-ported valves, manifolds, or fittings paired with compression-end tubing.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the supply line completely before disassembling or installing any compression fitting. Hand-tighten the compression nut first, then advance with a wrench per standard practice — avoid over-tightening, which can deform the ferrule and cause leaks. Verify all connections meet local plumbing code and applicable IPC or IFGC requirements before returning the system to service.
