Parker GBMT-662 Compression Male Branch Tee 3/8 in

Product Description

The PARKER GBMT-662 is a compression tube male branch tee designed for use in fluid and gas handling systems where corrosion resistance and chemical compatibility are critical. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting connects a branch line to a main run while providing a male threaded port on one leg. It accepts tubing with a 3/8 inch outside diameter and uses a plastic grip-type compression mechanism for a secure, leak-resistant seal without the need for soldering or welding. It is a lightweight component at 0.15 pounds, suited for installation in tight or chemically aggressive environments.

This fitting is used in applications that require high chemical resistance, including semiconductor fabrication, pharmaceutical processing, laboratory fluid distribution, and industrial chemical handling systems. The PFA and PTFE construction makes it well-suited for aggressive media such as acids, solvents, and high-purity fluids. It is typically installed by plumbers, pipefitters, or instrumentation technicians working on tubing assemblies that demand clean, reliable connections in corrosive or high-purity service.

Key Features

• PFA and PTFE construction provides excellent chemical resistance for aggressive fluid and gas service
• Compression-style connection accepts 3/8 inch OD tubing without soldering or special tooling
• Plastic grip-type compression mechanism seats securely for a leak-resistant seal
• Male branch tee configuration allows simultaneous inline and branch connections with a threaded male port
• Lightweight at 0.15 pounds, suitable for compact plumbing and instrumentation assemblies

Compatibility

Designed for use with 3/8 inch OD tubing in compression-style fluid and gas handling systems requiring PFA or PTFE chemical-resistant fittings.

Installation Notes

Installation is typically performed by qualified plumbers, pipefitters, or instrumentation technicians. Ensure all system pressure is relieved and the line is depressurized before disassembling or installing fittings. Hand-tighten compression connections and confirm proper tubing insertion depth before applying final torque per the system design specifications. Verify compatibility of all wetted materials with the specific media and operating conditions before placing the fitting in service.
