Eaton 1477X6 Brass Compression Female Branch Tee 3/8 in

Product Description

The EATON 1477X6 is a brass female branch tee fitting designed for compression tube connections with an NPT branch port. It accepts a 3/8 inch tube outside diameter on the compression ends and features a 17/32-24 inch thread size on the NPT connection. Constructed from brass, this fitting provides reliable sealing in fluid and gas distribution lines. It is suited for plumbing, HVAC, and industrial fluid system applications where a branch takeoff is needed without soldering or special tooling. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this type of fitting.

This fitting is used in residential and light commercial applications where a compression tube line requires a female branch tee configuration. The combination of compression and NPT end connections makes it adaptable to mixed-connection systems. Typical install scenarios include equipment supply lines, control valve branches, and instrument tap points in water and compatible fluid systems. The fitting ships individually and is stocked as a single-piece unit.

Key Features

• Brass construction for corrosion resistance and durability in wet or humid environments
• 3/8 inch tube outside diameter compression ends for tool-free, leak-resistant connections
• 17/32-24 inch NPT thread on the branch port for compatibility with standard threaded fittings
• Female branch tee configuration allows a single line to feed two directions with one fitting
• Meets ASA, ASME, and SAE standards for tube fitting applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems requiring a female branch tee with a 3/8 inch OD tube connection and NPT branch port.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off and depressurize the supply line fully before removing any existing fitting or installing this tee. Hand-tighten the compression nuts before applying a final turn with a wrench to avoid overtightening and deforming the ferrule. Verify thread compatibility and apply appropriate thread sealant to the NPT connection per IPC guidelines.
