Parker FBMT-668 Compression Male Branch Tee 3/8 in

Product Description

The PARKER FBMT-668 is a compression tube male branch tee designed for fluid and gas distribution systems where a single inline tube run needs a perpendicular branch outlet with a male threaded port. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting is built for applications demanding high chemical resistance and low friction across a wide temperature range. It accepts 3/8 inch tube OD on compression ends and uses a plastic grip-type compression mechanism for a secure, tool-assisted seal. Plumbers, process piping technicians, and chemical handling specialists install this fitting where corrosion-resistant, non-metallic connections are required.

This fitting is suited for residential and commercial fluid handling systems, laboratory distribution lines, chemical process piping, and pneumatic circuits where PFA or PTFE construction is specified for chemical compatibility. The male branch tee configuration allows a branch connection to be made off a continuous tube run, with the male threaded port connecting directly to a female-threaded port or manifold. It is commonly installed in systems handling aggressive chemicals, ultra-pure water, or other media incompatible with metal fittings.

Key Features

• PFA and PTFE construction provides broad chemical resistance and suitability for high-purity applications
• 3/8 inch tube OD compression ends accept standard tubing without soldering or flaring
• Male branch tee configuration enables a perpendicular branch outlet off a continuous tube run
• Plastic grip-type compression sleeve ensures a reliable, leak-resistant seal
• Lightweight at 0.1 pounds, suitable for space-constrained installations

Compatibility

Designed as an OEM-style compression fitting for use with 3/8 inch OD tubing in non-metallic fluid and gas distribution systems requiring PFA or PTFE wetted materials.

Installation Notes

Installation is typically performed by licensed plumbers or process piping technicians familiar with compression-style fittings. Depressurize and drain the system fully before disconnecting or installing any fitting. Hand-tighten the compression nut first, then use a wrench for a final snug turn — avoid over-tightening, which can crack plastic compression components. Verify tube OD and thread size match the fitting specifications before installation, and consult applicable plumbing or process piping codes for your jurisdiction.
