Parker FB4MTS4-HBLK Male Swivel Branch Tee 1/4 in

Product Description

The PARKER FB4MTS4-HBLK is a push-to-connect male swivel branch tee tube fitting designed for tube-to-pipe connections in fluid handling and pneumatic systems. Built from Kynar (PVDF) with an FKM o-ring, this fitting accepts 1/4-inch OD tubing and connects to a 1/4-inch NPTF male thread. It is rated to 250 psi and carries a vacuum rating of 28 in-Hg, making it suitable for both pressure and light vacuum service. The black color finish and swivel branch design allow for flexible routing in tight plumbing and instrumentation layouts. Plumbers, fluid system technicians, and instrumentation specialists are the typical installers.

This fitting is used in residential and commercial plumbing, pneumatic control lines, chemical handling, and instrumentation tubing systems where a branch connection is needed off a main tube run. The push-to-connect design allows for tool-free tube insertion, reducing installation time on new construction and service calls alike. The Kynar construction makes it well suited for mildly corrosive fluid environments where standard brass or nylon fittings may not be appropriate.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4-inch OD push-to-connect tubing with 1/4-inch NPTF male pipe thread connections.

Installation Notes

Installation should be performed by a qualified plumber or fluid systems technician. Depressurize and isolate the system before removing or installing any fittings. Ensure tubing is cut cleanly and squarely and deburred before insertion into the push-to-connect port to achieve a proper seal. Verify that system operating pressure and fluid compatibility are within the rated limits of this fitting before placing the system back in service.
