Parker FB6MC2-HBLK Push-to-connect Fitting 3/8in Od

Product Description

The PARKER FB6MC2-HBLK is a push-to-connect tube fitting connector designed for fast, tool-free tube connections in pneumatic and fluid-handling systems. Built from Kynar (PVDF) with an FKM o-ring, this fitting handles up to 250 psi and a vacuum rating of 28 inches-Hg, making it suitable for both pressure and vacuum service. It accepts 3/8 inch OD tubing and connects to a 1/8 inch NPTF threaded port. The black color indicates its Kynar construction at a glance. HVAC technicians, plumbers, and industrial service pros install this fitting where corrosion resistance and quick connect-disconnect cycles are required.

This connector is used in residential and light commercial applications where chemical resistance is a priority, including refrigerant-adjacent pneumatic controls, chemical feed lines, and fluid transfer systems. The NPTF thread provides a pressure-tight mechanical seal without sealant tape in many installations, though standard practice on threaded joints varies by application and local code. The compact body fits in tight panel and cabinet spaces where conventional compression fittings are impractical.

Key Features

• Kynar (PVDF) body provides excellent chemical and corrosion resistance
• FKM o-ring sealing element rated for a wide range of fluid compatibility
• 250 psi maximum working pressure for pneumatic and fluid service
• 28 inches-Hg vacuum rating supports both pressure and vacuum applications
• 1/8 inch NPTF threaded port delivers a pressure-tight connection
• Push-to-connect design allows fast, tool-free tube insertion and release

Compatibility

Designed as an OEM-style push-to-connect replacement connector for systems using 3/8 inch OD tubing with a 1/8 inch NPTF threaded port where Kynar or chemical-resistant fittings are specified.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid-handling system requirements. De-pressurize and isolate the line completely before removing or installing any fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect collet to achieve a proper seal. Thread engagement should follow NPTF best practices; consult applicable plumbing or mechanical codes for your jurisdiction.
