Parker FB5MC2-HBLK Push-to-connect Fitting 5/16in Od

Product Description

The PARKER FB5MC2-HBLK is a push-to-connect tube fitting connector designed for quick, tool-free tube connections in fluid and pneumatic systems. Constructed from Kynar (PVDF), this fitting handles up to 250 psi and carries a vacuum rating of 28 in-Hg, making it suitable for both pressure and vacuum applications. It accepts 5/16 inches outside diameter tubing and features a 1/8 inches NPTF threaded end for secure, leak-resistant installation into ported equipment or manifolds. The FKM o-ring provides chemical compatibility across a broad range of media. Plumbers, HVAC technicians, and fluid-system installers work with this fitting type in both light industrial and mechanical service environments.

This connector is used in residential and commercial applications where push-to-connect plumbing or pneumatic tubing must terminate at a threaded port. Typical install scenarios include compressed air distribution, chemical fluid lines, and refrigeration or HVAC auxiliary tubing runs where Kynar material resistance to aggressive chemicals is required. The black color finish allows for quick visual identification in multi-line installations. Its compact form factor suits panel-mount and tight-space installations.

Key Features

• Kynar (PVDF) body construction for excellent chemical resistance
• Push-to-connect design enables fast, tool-free tube insertion and release
• Rated to 250 psi working pressure
• Vacuum rated to 28 in-Hg for suction-side applications
• FKM o-ring for broad chemical and temperature compatibility
• 1/8 inches NPTF thread provides a pressure-tight seal without additional sealant tape in many applications

Compatibility

Designed as an OEM-style push-to-connect connector fitting for systems using 5/16 inches outside diameter tubing with a 1/8 inches NPTF threaded port connection.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or fluid-system mechanics. Depressurize and isolate the system fully before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and deburred before insertion to achieve a proper seal. Verify thread compatibility and hand-tighten the NPTF connection before applying final torque with an appropriate wrench; consult applicable IPC or system manufacturer guidelines for thread engagement requirements.
