Parker FB6MC6-HBLK Push-to-connect Fitting 3/8 in

Product Description

The PARKER FB6MC6-HBLK is a push-to-connect tube fitting connector designed for fast, tool-free tubing connections in fluid handling and pneumatic systems. Built from Kynar (PVDF) with an FKM O-ring, this fitting handles up to 250 psi and carries a vacuum rating of 28 in-Hg. It accepts 3/8-inch OD tubing and connects via a 3/8-inch NPTF thread. The black color coding aids quick identification on the job. Licensed plumbers, HVAC technicians, and industrial pipe fitters install this type of fitting where chemical resistance and pressure performance are required.

This connector suits residential and light commercial fluid system applications where Kynar construction is specified for chemical resistance. It is appropriate for water treatment lines, chemical feed systems, pneumatic control tubing, and similar installations that demand a reliable push-to-connect interface at moderate to high pressures. The compact form factor fits standard access spaces without requiring additional sealant at the NPTF thread interface under normal conditions.

Key Features

• Push-to-connect design allows fast, tool-free tubing insertion for 3/8-inch OD tube
• Kynar (PVDF) body offers strong chemical resistance for demanding fluid environments
• FKM O-ring provides a reliable seal compatible with a wide range of process fluids
• Rated to 250 psi working pressure with a 28 in-Hg vacuum rating
• 3/8-inch NPTF thread for secure, pressure-tight male thread connections
• Black color for easy visual identification in multi-fitting installations

Compatibility

Designed as an OEM-style push-to-connect connector for systems using 3/8-inch OD tubing with 3/8-inch NPTF threaded ports where Kynar construction and FKM seals are required.

Installation Notes

Installation of this fitting should be performed by a qualified plumber, HVAC technician, or industrial pipe fitter familiar with push-to-connect systems and NPTF thread engagement. Shut off and depressurize the system completely before removing or installing any fitting. Confirm tubing is cut squarely and deburred before insertion to ensure a proper O-ring seal. Verify fluid and pressure compatibility with Kynar and FKM materials before installation in chemical service applications.
