Parker FB6TCB6 Tube to Barb Connector 3/8 in Kynar

Product Description

The PARKER FB6TCB6 is a push-to-connect tube-to-barb connector designed for fluid handling systems that require a secure, tool-free connection between tubing and barbed fittings. Constructed from Kynar (polyvinylidene fluoride), it delivers strong chemical resistance suitable for demanding fluid control applications. The fitting accepts 3/8 inch outside diameter tubing on the push-to-connect side and 3/8 inch inside diameter tubing on the barb side. Rated to 250 psi and capable of handling up to 28 inches of mercury (in-Hg) vacuum, it suits both pressure and vacuum service. The FKM o-ring provides a reliable seal across a broad range of fluid types. Plumbers, HVAC technicians, and fluid system installers work with this fitting in both residential and light commercial settings.

This connector is suited for use in chemical transfer, water treatment, HVAC condensate management, and similar fluid control applications where Kynar material compatibility is required. Its push-to-connect design allows for fast, repeatable connections without threading or solvent welding. The black color and compact form factor make it practical for installations in tight spaces where a low-profile fitting is needed.

Key Features

• Kynar (PVDF) construction for high chemical resistance
• Push-to-connect design for tool-free installation
• Rated to 250 psi working pressure
• Vacuum rating of 28 in-Hg for dual-service applications
• FKM o-ring seal for broad fluid compatibility
• 3/8 inch OD tube inlet by 3/8 inch ID barb outlet

Compatibility

Designed as a direct-fit push-to-connect tube-to-barb connector for 3/8 inch OD tubing systems using Kynar-compatible fluid handling components.

Installation Notes

Installation does not require tools on the push-to-connect side. Shut off all fluid flow and depressurize the line before connecting or disconnecting. Verify tubing is cut cleanly and squarely before insertion to ensure a proper seal. Follow applicable plumbing and mechanical codes for the jurisdiction where the fitting is installed.
