Parker FB6WY6-HBLK Push-to-connect Union 3/8 Inch Od

Product Description

The PARKER FB6WY6-HBLK is a push-to-connect union tube fitting designed for quick, tool-free connections in fluid and pneumatic systems. Constructed from Kynar (PVDF), this fitting offers strong resistance to chemicals, UV exposure, and high-pressure conditions up to 250 psi. The union configuration joins two tube runs of equal diameter, making it a practical choice for inline connections where flexibility and chemical compatibility are required. It is sold individually and is suited for installation by plumbers, fluid system technicians, and industrial maintenance professionals working with compatible tubing.

This fitting is designed for use with 3/8 inch OD tubing in applications where chemical resistance and pressure integrity are critical. Typical installations include chemical process lines, water treatment systems, and industrial fluid handling setups. The FKM o-ring provides a reliable seal across a range of fluid types, and the 28 in-Hg vacuum rating makes this fitting suitable for light vacuum service as well as positive-pressure applications. The black Kynar body is well-suited for environments with UV exposure or aggressive media.

Installation Notes

Installation is typically performed by a licensed plumber or fluid system technician. Before servicing any line, depressurize and drain the system fully. Ensure tubing ends are cut cleanly and squarely with no burrs before insertion into the fitting to maintain a proper seal. Verify that the tubing OD matches the fitting specification before assembly.
