Parker FB4TEB4 Elbow Barb Tube Fitting 1/4 in Kynar

Product Description

The PARKER FB4TEB4 is a push-to-connect elbow barb tube fitting designed for low-force tube assembly in fluid handling and pneumatic systems. It connects tubing with a 1/4 inch inside diameter to 1/4 inch outside diameter tubing at a 90-degree angle, making direction changes in tight plumbing runs straightforward. Constructed from Kynar (PVDF), this fitting handles up to 250 psi working pressure and carries a vacuum rating of 28 in-Hg. The FKM o-ring provides reliable sealing against a broad range of process fluids. Plumbers, HVAC technicians, and industrial maintenance professionals install this fitting in chemical, water treatment, and fluid transfer applications.

This fitting is suited for residential and light commercial fluid systems where corrosion resistance and secure push-to-connect assembly are required. Kynar construction makes it appropriate for mildly aggressive chemical environments where standard thermoplastic fittings may degrade. Typical install scenarios include water purification lines, chemical dosing systems, and condensate management lines found in HVAC equipment. The elbow barb configuration allows tubing to be routed around corners without additional adapters or heat forming.

Key Features

• Kynar (PVDF) body construction resists chemical attack and UV exposure
• Push-to-connect design allows fast, tool-free tube insertion
• 250 psi working pressure rating
• 28 in-Hg vacuum rating suitable for low-pressure suction lines
• FKM o-ring sealing material compatible with a wide range of process fluids
• 90-degree elbow barb geometry for in-line direction changes

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for 1/4 inch ID by 1/4 inch OD flexible tubing in fluid handling, pneumatic, and condensate drain applications.

Installation Notes

Depressurize and drain the line before removing or installing any tube fitting. Ensure tubing ends are cut cleanly and squarely to achieve a proper seal at the barb connection. This fitting is typically installed by licensed plumbers or HVAC technicians following applicable IPC and IFGC guidelines for fluid system components. Inspect the FKM o-ring for damage before assembly and verify the tube is fully seated before returning the system to service.
