Parker FB4TCB4 Tube to Barb Connector 1/4 Inch Kynar

Product Description

The PARKER FB4TCB4 is a push-to-connect tube-to-barb fitting designed for quick, tool-free inline connections in fluid and pneumatic systems. Constructed from Kynar (PVDF), this fitting handles up to 250 psi working pressure and a vacuum rating of 28 in-Hg, making it suitable for demanding chemical, water treatment, and process environments. The FKM o-ring seals the connection and provides resistance to oils, fuels, and many aggressive fluids. Licensed plumbing and mechanical contractors, as well as industrial maintenance technicians, commonly install this fitting in low-to-medium pressure tubing runs where a secure, vibration-resistant connection is required without tools.

This fitting is suited for residential and light commercial plumbing, chemical transfer, water treatment, HVAC condensate management, and process piping applications where 1/4-inch OD tubing meets a 1/4-inch ID barb port. The Kynar construction holds up well against chlorine, acids, and other corrosive media encountered in water treatment and pool chemical systems. It is sold individually and is appropriate for retrofit or new-installation work wherever a compact inline barb-to-tube transition is needed.

Key Features

• Kynar (PVDF) construction provides excellent chemical and corrosion resistance
• Push-to-connect design enables tool-free installation on 1/4-inch OD tubing
• FKM o-ring seal rated for compatibility with oils, fuels, and aggressive process fluids
• 250 psi maximum working pressure for reliable performance in pressurized systems
• 28 in-Hg vacuum rating supports use in suction-side and low-pressure vacuum lines
• Black color for easy visual identification in multi-line installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch OD push-to-connect tubing systems requiring a barb transition, commonly found in chemical dosing, water treatment, HVAC, and process fluid applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician following applicable IPC or local plumbing code requirements. Before servicing any connected line, depressurize and isolate the system completely. Ensure tubing is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect end to achieve a proper seal. Do not exceed the rated working pressure or vacuum rating of this fitting.
