Parker FB6FC6-HBLK Push-to-connect Tube Fitting 3/8 in

Product Description

The PARKER FB6FC6-HBLK is a push-to-connect tube-to-pipe connector fitting designed for fast, tool-free tube connections in fluid and pneumatic systems. Manufactured from Kynar (PVDF), this fitting handles working pressures up to 250 psi and is rated for vacuum service up to 28 in-Hg. It accepts 3/8 inch OD tubing and connects to 3/8 inch NPTF pipe threads. The FKM o-ring provides reliable sealing compatibility with a broad range of fluids and gases. Licensed plumbers, HVAC technicians, and industrial service technicians install this fitting where a secure, push-in tube-to-pipe transition is required.

This fitting is suited for residential and commercial plumbing, HVAC, and light industrial fluid-handling applications. The Kynar construction offers strong resistance to chemicals and UV exposure, making it appropriate for both indoor and outdoor installations. The black color finish aids visual identification in multi-line installations. With a compact package footprint and a minimum order quantity of one, it is a practical replacement or field-repair option for single-unit service calls.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic. Depressurize and isolate the system completely before removing or installing any fitting. Ensure tubing is cut cleanly and squarely, and that the tube end is free of burrs before inserting into the push-to-connect collet. Verify that the NPTF threads are clean and that appropriate thread sealant is applied per local plumbing codes before making up the pipe connection.
