Parker FB6FC8-HBLK Push-to-connect Connector 3/8 Od

Product Description

The PARKER FB6FC8-HBLK is a push-to-connect tube fitting connector rated for 250 psi and vacuum service up to 28 in-Hg. Manufactured from Kynar with an FKM o-ring, this fitting handles aggressive fluid and chemical environments where standard thermoplastics would degrade. The black color provides easy visual identification in multi-line systems. It connects 3/8 inch OD tubing to a 1/2 inch NPTF threaded port, making it a fast, tool-free connection option for plumbing, fluid handling, and industrial process lines. This fitting is typically installed by licensed plumbers, HVAC technicians, or industrial maintenance pros.

This connector is suited for applications requiring a secure, leak-resistant push-to-connect interface between tubing and a threaded port. Common use cases include fluid transfer systems, chemical process lines, and compressed air or vacuum circuits where Kynar chemical resistance is required. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on sealant tape. The FKM o-ring ensures compatibility with a broad range of chemical media including fuels, hydraulic fluids, and halogenated solvents.

Key Features

• Kynar body construction for high chemical and corrosion resistance
• FKM o-ring for compatibility with aggressive media including fuels and solvents
• NPTF thread type for pressure-tight dry-seal connections
• 250 psi pressure rating for demanding fluid system applications
• Vacuum rated to 28 in-Hg for both pressure and vacuum service
• Push-to-connect design allows fast, tool-free tube installation

Compatibility

Designed for use with 3/8 inch OD tubing and 1/2 inch NPTF threaded ports in chemical, fluid handling, and industrial process applications requiring Kynar push-to-connect fittings.

Installation Notes

Shut off all fluid supply and relieve system pressure before removing or installing any tube fitting. Verify tubing is cut square and free of burrs before insertion to ensure a proper o-ring seal. NPTF threads provide a dry-seal fit, but consult applicable codes such as IPC or local mechanical codes regarding the use of thread sealant in your jurisdiction. Confirm system media compatibility with Kynar and FKM before placing the fitting in service.
