Parker FB4FC2-HBLK Push-to-connect Fitting 1/4 Od 1/8 Nptf

Product Description

The PARKER FB4FC2-HBLK is a push-to-connect tube fitting connector designed for quick, tool-free tube connections in pneumatic and fluid handling systems. Constructed from Kynar (PVDF) with an FKM O-ring, this fitting delivers strong chemical resistance and reliable sealing across a wide range of media. It accepts 1/4 inch OD tubing and threads into a 1/8 inch NPTF port. With a 250 psi pressure rating and a vacuum rating of 28 in-Hg, it suits both pressure and vacuum line applications. Plumbers, HVAC technicians, and instrumentation specialists install this type of fitting where fast, repeatable connections are required.

This connector is suited for residential and light commercial pneumatic control lines, chemical feed systems, instrumentation tubing, and other fluid handling circuits where Kynar material compatibility is required. The black color coding aids in quick visual identification on multi-line installations. Its compact form factor makes it practical in panel-mount or tight-clearance installations where standard compression or flare fittings are less practical.

Key Features

• Kynar (PVDF) body provides excellent chemical and UV resistance
• FKM O-ring sealing for compatibility with aggressive fluids and refrigerants
• 250 psi working pressure rating
• 28 in-Hg vacuum rating supports both pressure and vacuum service
• 1/8 inch NPTF male thread for secure, leak-resistant port connection
• Push-to-connect design accepts 1/4 inch OD tubing without tools

Compatibility

Designed as an OEM-style replacement push-to-connect connector for pneumatic and fluid systems using 1/4 inch OD tubing with 1/8 inch NPTF ported equipment.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or instrumentation technicians. Depressurize and isolate the line completely before removing or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the fitting to achieve a proper seal. Verify thread type and taper at the port — NPTF threads differ from NPT and should not be interchanged without confirming compatibility.
