Parker FB6MC8-HBLK Push-to-connect Fitting 3/8 Od

Product Description

The PARKER FB6MC8-HBLK is a push-to-connect tube fitting connector designed for fast, tool-free tube connections in fluid and pneumatic systems. Built from Kynar (PVDF) with a black finish, this fitting accepts 3/8 inch OD tubing and threads into a 1/2 inch NPTF female port. The FKM o-ring provides reliable sealing across a wide range of fluids and temperatures. Rated to 250 psi and capable of handling up to 28 inches Hg of vacuum, this connector suits demanding plumbing, chemical handling, and instrumentation applications where both pressure and vacuum service are required. Licensed plumbers, pipefitters, and instrumentation techs are the typical installers.

This fitting is suited for use in residential and commercial plumbing, chemical process lines, and fluid transfer systems where corrosion resistance and secure push-to-connect performance are required. Kynar construction makes it appropriate for aggressive media including certain acids, bases, and chlorinated fluids. The NPTF thread type provides a pressure-tight mechanical seal at the threaded connection without relying solely on sealant. Sold individually.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters. Depressurize and isolate the line before disassembly or fitting installation. Ensure the tube end is cut square, deburred, and free of contamination before inserting into the push-to-connect port. Apply thread sealant or PTFE tape to the NPTF threads per applicable plumbing code requirements, and verify the tube is fully seated before restoring pressure.
