Parker 6 V5BU-S Flareless Bite-type Fitting 3/8 in

Product Description

The PARKER 6 V5BU-S is a flareless bite-type tube fitting designed to create leak-free connections in hydraulic and fluid power lines without requiring flared tubing ends. The fitting accepts 3/8 inch tube OD and uses a 9/16-18 NPTF thread, providing a pressure-rated, dryseal connection that eliminates the need for additional thread sealant in many applications. Bite-type fittings use a ferrule that bites into the tube wall on tightening, forming a mechanical grip and seal in a single assembly step. This fitting is typically installed by hydraulic technicians, plumbers, and fluid system assemblers working on industrial or mobile equipment.

This fitting is suited for applications where tube flaring is impractical or where space constraints make flareless assembly preferable. Common installations include hydraulic control lines, pneumatic circuits, lubrication systems, and instrument tubing runs. The NPTF thread form is designed for dryseal performance, making it a standard choice in fluid power and process piping systems that require reliable sealing at the threaded port connection.

Key Features

• Flareless bite-type design eliminates need for tube flaring during assembly
• 3/8 inch tube OD for compatibility with standard hydraulic and fluid power tubing
• 9/16-18 NPTF dryseal thread provides a pressure-rated, leak-resistant port connection
• Compact, single-piece construction suited for tight installation spaces
• Reusable fitting design allows disassembly and reassembly in service applications

Compatibility

Designed as an OEM-style flareless bite-type fitting for use with 3/8 inch OD tubing in hydraulic, pneumatic, and fluid power systems requiring a 9/16-18 NPTF ported connection.

Installation Notes

Installation should be performed by a qualified hydraulic or fluid system technician. Depressurize and isolate the fluid circuit completely before disassembling or installing any tube fitting. Ensure tube ends are cut square, deburred, and free of contamination before inserting into the fitting body. Torque to the fitting manufacturer's published assembly specifications for the tube OD and material being used.
