Parker GBMT-442 Compression Male Branch Tee 1/4 in Od

Product Description

The PARKER GBMT-442 is a compression-style male branch tee fitting designed for use with 1/4 inch outside diameter tubing. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting delivers excellent chemical resistance and is well suited for high-purity fluid and gas handling applications. The plastic grip-type compression mechanism allows secure, leak-resistant connections without the need for solder, flare tools, or thread sealant. At 0.1 pounds, this is a lightweight, single-piece fitting intended for installation by plumbers, process technicians, and instrumentation professionals working with small-bore tubing systems.

This male branch tee is used in applications where a branch connection is required off a main tubing run while also providing a male threaded port. Typical installations include chemical processing lines, laboratory fluid distribution systems, semiconductor manufacturing equipment, and other environments where fluoropolymer materials are required for compatibility with aggressive media. The compression fitting design makes it suitable for both new installations and field repairs where quick, reliable connections are needed in tight spaces.

Key Features

• PFA and PTFE construction provides broad chemical resistance for demanding fluid and gas service
• Compression-style connection accommodates 1/4 inch OD tubing without soldering or special tooling
• Plastic grip-type design allows controlled pull-up and secure tube retention
• Male branch tee configuration provides a three-way connection with an inline male port
• Lightweight at 0.1 pounds, suitable for compact instrumentation and process plumbing layouts

Compatibility

Designed as an OEM-style compression fitting for use with 1/4 inch outside diameter tubing in fluoropolymer-compatible plumbing and instrumentation systems.

Installation Notes

This fitting is typically installed by licensed plumbers or instrumentation technicians. Before installation, shut off flow and depressurize the tubing circuit completely. Insert tubing to the full depth of the fitting body and hand-tighten the compression nut before applying a final quarter to half turn with a wrench — do not overtighten fluoropolymer fittings, as the plastic components can crack under excessive torque. Verify all connections are leak-free under system operating pressure before returning the line to service.
