Parker FBMT-444 Compression Male Branch Tee 1/4 in

Product Description

The PARKER FBMT-444 is a compression tube male branch tee designed for use in fluid and gas distribution lines requiring a reliable, chemically resistant branch connection. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting accepts 1/4 inch outside diameter tubing and uses a plastic grip compression mechanism to create a leak-resistant seal without the need for solder, flare tools, or thread sealant. It is suited for laboratory, instrumentation, and process plumbing applications where chemical compatibility and purity of flow path are critical. Licensed plumbers and instrumentation technicians are the typical installers of this fitting type.

This fitting is applied in systems handling aggressive chemicals, high-purity fluids, or gases where metal fittings would corrode or contaminate the medium. The male branch tee configuration allows a single inline tube run to be teed off with a male-threaded port, making it useful in manifold assemblies, sample lines, and analytical instrument plumbing. It is equally applicable in semiconductor fab support lines, pharmaceutical process equipment, and chemical handling skids where PFA and PTFE materials are specified by design.

Key Features

• PFA and PTFE construction provides excellent chemical resistance and low extractables
• Compression-style grip fitting accepts 1/4 inch OD tubing without solder or flaring
• Plastic grip type simplifies hand-tightening installation in sensitive or cleanroom environments
• Male branch tee configuration enables inline branching with a threaded male port
• Lightweight at 0.05 pounds, suitable for compact instrumentation assemblies

Compatibility

Designed as an OEM-style compression fitting for use with 1/4 inch outside diameter tubing in PFA or PTFE tubing systems requiring a male branch tee connection.

Installation Notes

Installation is typically performed by licensed plumbers or instrumentation technicians familiar with compression fittings. Before installation, depressurize and purge the line of any fluid or gas. Ensure tubing is cut cleanly and squarely to achieve a proper compression seal. Do not over-tighten the compression nut, as PFA and PTFE fittings are designed for hand-tight plus a controlled partial turn per the fitting manufacturer guidelines.
