Parker GBMT-666 Compression Male Branch Tee 3/8 in

Product Description

The PARKER GBMT-666 is a compression tube male branch tee designed for use in fluid and gas distribution systems requiring chemically resistant fittings. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting handles aggressive media that would degrade standard metal or general-purpose plastic fittings. It accommodates 3/8 inch tube outside diameter and uses a plastic grip compression mechanism, eliminating the need for soldering or flaring. Weighing 0.15 pounds, it is a lightweight but chemically robust choice for instrumentation and process tubing runs. Licensed plumbers, process technicians, and instrumentation specialists are the typical installers.

This fitting is suited for residential laboratory equipment, industrial process lines, chemical handling systems, and semiconductor fluid distribution where PFA and PTFE materials are specified for purity or corrosion resistance. The male branch tee configuration allows a branch connection off a main tube run while providing a male threaded port, making it practical for compact manifold and distribution assemblies. It is typically used in low to moderate pressure tubing systems where chemical compatibility is the primary selection criterion.

Key Features

• PFA and PTFE construction provides broad chemical resistance for aggressive fluid and gas service
• Compression-style connection on 3/8 inch tube OD eliminates soldering and flaring
• Plastic grip compression mechanism for a secure, tool-assisted tube hold
• Male branch tee configuration supports in-line branch takeoffs with a threaded male port
• Lightweight at 0.15 pounds, suitable for space-constrained instrument panels and process assemblies

Compatibility

Designed as an OEM-style compression fitting for 3/8 inch OD tubing in systems specifying PFA or PTFE-compatible components.

Installation Notes

Installation is typically performed by licensed plumbers or qualified instrumentation technicians. Before installing or removing this fitting, isolate and depressurize the tubing system and purge any hazardous media per site safety procedures. Ensure tube ends are cut square and deburred before insertion to achieve a proper compression seal. Follow applicable codes such as IPC or system-specific pressure ratings when selecting this fitting for a given service application.
