Parker FB4MTS2-HBLK Male Swivel Branch Tee 1/4 in Od

Product Description

The PARKER FB4MTS2-HBLK is a push-to-connect male swivel branch tee tube fitting designed for tube-to-pipe connections in pneumatic and fluid control systems. It accepts 1/4 inch OD tubing and connects to a 1/8 inch NPTF male thread on the branch port. The body is molded from Kynar, a high-performance fluoropolymer that resists aggressive chemicals and elevated temperatures. FKM o-rings provide a reliable seal at the push-to-connect ports. Rated to 250 psi with a vacuum rating of 28 inches Hg, this fitting handles both pressure and vacuum service. It is installed by licensed plumbers, HVAC technicians, and instrumentation trades on tubing runs requiring a branch takeoff with a threaded pipe connection.

This fitting is suited for residential and light commercial pneumatic controls, instrumentation lines, chemical feed systems, and HVAC pneumatic control tubing. The Kynar construction makes it appropriate for mildly corrosive fluid and gas service where standard acetal or nylon fittings are not compatible. The black color finish allows for easy visual differentiation in multi-line installations. The swivel branch design simplifies alignment during installation, reducing stress on connected tubing.

Key Features

• Push-to-connect design accepts 1/4 inch OD tubing without tools for quick, repeatable connections
• Kynar body construction for chemical resistance in corrosive service environments
• FKM o-rings compatible with a broad range of fluids and refrigerants

Compatibility

Designed as an OEM-style push-to-connect fitting for systems using 1/4 inch OD tubing and 1/8 inch NPTF threaded pipe ports in pneumatic control or fluid handling applications.

Installation Notes

Depressurize and drain the system completely before removing or installing any fittings. Ensure tubing is cut square and deburred before inserting into the push-to-connect port to achieve a proper seal. Thread engagement should follow NPTF hand-tight-plus standard practice per applicable plumbing codes. Do not exceed the rated working pressure of 250 psi or the vacuum rating of 28 inches Hg during service.
