Parker FB4TU4-HBLK Union Tee Fitting 1/4 in Od Kynar

Product Description

The PARKER FB4TU4-HBLK is a push-to-connect union tee tube fitting designed for tube-to-tube connections in fluid and pneumatic systems. Constructed from Kynar (PVDF) with a black finish, this fitting accepts 1/4 inch OD tubing on all three ports and creates a leak-resistant seal without tools or thread sealant. The FKM o-ring provides compatibility with a wide range of aggressive media. Rated to 250 psi and capable of handling a vacuum rating of 28 inches Hg, it suits both pressure and vacuum applications. Licensed plumbers, HVAC technicians, and industrial maintenance professionals commonly install this fitting in chemical transfer, instrumentation, and fluid control lines.

This union tee is suited for residential and light commercial instrumentation lines, chemical handling systems, and plumbing applications where corrosion-resistant fittings are required. The Kynar body resists many acids, bases, and solvents, making it a practical choice for water treatment, chemical processing, and specialty HVAC fluid lines where standard brass or polymer fittings are not appropriate. All three ports accept 1/4 inch OD tubing for in-line branching without additional adapters.

Compatibility

Designed as a direct push-to-connect union tee for systems using 1/4 inch OD tubing. Consult system specifications to confirm tube material and pressure ratings are compatible before installation.

Installation Notes

Installation requires no tools for tube insertion — ensure tubing is cut cleanly and squarely and that the outer surface is free of burrs or debris before seating. Depressurize and de-energize any system before servicing fittings. To release tubing, depress the collet ring while pulling the tube free. Follow applicable plumbing or instrumentation codes for the jurisdiction and service environment.
