Parker FB8WY6-HBLK Push-to-connect Union 1/2x3/8 in Od

Product Description

The PARKER FB8WY6-HBLK is a push-to-connect union tube fitting designed to join two tubes of different outside diameters without tools or threaded connections. Constructed from Kynar (PVDF) with an FKM o-ring, it handles up to 250 psi and carries a vacuum rating of 28 in-Hg. The black color coding helps identify the fitting on multi-line installations. This fitting suits plumbing, chemical handling, and instrumentation systems where a quick, leak-resistant connection is required. Plumbers, pipefitters, and instrumentation technicians are the typical installers.

This union fitting accommodates a 1/2 inch OD tube on one end and a 3/8 inch OD tube on the other, making it a direct reducer union in push-to-connect form. It is suited for residential and light commercial applications involving water treatment, chemical feed lines, pneumatic instrumentation, and similar fluid-handling systems where Kynar chemical resistance is needed. Its compact body keeps installation space requirements low.

Compatibility

Designed as an OEM-style push-to-connect union fitting for systems using 1/2 inch OD and 3/8 inch OD tubing in fluid-handling or pneumatic instrumentation applications.

Installation Notes

Installation is performed by plumbers or instrumentation technicians. Shut off fluid supply and depressurize the line fully before inserting or removing tubing. Cut tubing square and deburr the end before insertion to ensure a proper seal. Verify tubing outside diameter is within the fitting's rated tolerance before final connection.
