Parker FB8MC8-HBLK Push-to-connect Fitting 1/2 in Kynar

Product Description

The PARKER FB8MC8-HBLK is a push-to-connect tube fitting connector designed for fast, tool-free tube connections in fluid and pneumatic systems. Built from Kynar, a chemically resistant polyvinylidene fluoride material, this fitting handles a working pressure of 250 psi and a vacuum rating of 28 in-Hg. The black color designation (HBLK) aids in system identification. Rated for tube outside diameter (OD) of 1/2 inch with a 1/2 inch NPTF thread connection, it is suited for plumbing, chemical handling, and industrial fluid distribution lines where corrosion resistance and leak-free performance are required. Installation requires no tools for tube insertion.

This fitting is appropriate for use in chemical processing, HVAC fluid circuits, water treatment, and similar applications where chemical-resistant materials and dependable push-to-connect performance are needed. The NPTF thread type provides a pressure-tight mechanical seal without relying solely on sealant tape. The FKM o-ring provides additional sealing integrity and broad chemical compatibility. This connector is typically installed by plumbers, HVAC technicians, or industrial maintenance professionals in both light commercial and residential settings.

Key Features

• 1/2 inch NPTF thread for pressure-tight connections

Compatibility

Designed as an OEM-style push-to-connect connector for systems using 1/2 inch OD tubing with 1/2 inch NPTF female or male port connections in fluid handling and pneumatic applications.

Installation Notes

This fitting should be installed by a qualified plumber or fluid systems technician. Depressurize and drain the line completely before removing any existing fittings. Ensure the tube end is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect collar. NPTF threads are designed to seal on thread interference; apply thread sealant per the system manufacturer or applicable code requirements such as IPC or IFGC.
