Ham-let 3102503 Compression Female Branch Tee 3/8 in

Product Description

The HAM-LET 3102503 is a brass compression tube female branch tee designed for secure, leak-resistant connections in fluid and gas distribution systems. It features compression fittings on two ports and a female NPT (FNPT) thread on the branch port, creating a tee configuration that allows a threaded branch takeoff from a compression tube run. The fitting is machined from brass and conforms to ASTM B68 and ASTM B75 material standards. With a maximum working pressure of 2,600 psi, it is suited for demanding hydraulic and pneumatic applications. Licensed plumbers, pipefitters, and HVAC technicians install this fitting in instrumentation lines, refrigeration piping, and process fluid systems.

This fitting is used in residential and commercial installations where a compression tube run requires a branch connection to a female-threaded port. The 3/8 inch thread size accommodates standard tube and pipe sizes common in HVAC, refrigeration, and fluid handling systems. Its tee configuration makes it suitable for instrument takeoffs, sample points, or supply branch lines where a rigid, vibration-resistant mechanical connection is required without soldering or welding.

Compatibility

Designed as an OEM-style replacement compatible with the Swagelok part number B-810-3TTF. Suitable for use in compression tube systems requiring a female branch tee in 3/8 inch thread size with brass construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including IPC and IFGC where applicable. Depressurize and isolate the line completely before disassembling any existing fittings or installing this tee. Compression fittings require proper tube preparation, including clean square cuts and deburring, to ensure a leak-free seat. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
