Parker 6 Vbu-s Flareless Bite-type Male Elbow Steel

Product Description

The PARKER 6 VBU-S is a flareless bite-type tube male elbow designed for use in high-pressure hydraulic and instrumentation tubing systems. This fitting connects 3/8-inch OD tubing to a 1/4-inch NPTF male thread port at a 45-degree elbow angle with a 24-degree flared seat. Constructed from steel, it is rated for a maximum working pressure of 5,000 psi. The bite-type design creates a secure mechanical grip on the tube without requiring pre-flaring, making it suitable for tight routing situations where a direction change is needed. Licensed plumbers, pipefitters, and hydraulic system technicians are the typical installers of this fitting type.

This fitting is used in industrial, fluid power, and instrumentation applications where rigid or semi-rigid tubing must transition through a 45-degree change in direction and connect to an NPTF-threaded port. It is well-suited for hydraulic lines, pneumatic systems, and process instrumentation tubing in both fixed industrial machinery and mobile equipment environments. The steel construction makes it appropriate for systems operating under sustained high-pressure conditions.

Key Features

• 45-degree elbow configuration for direction changes in tight plumbing runs
• Flareless bite-type design eliminates the need for tube pre-flaring
• 24-degree flared seat angle for a reliable metal-to-metal seal
• Rated to 5,000 psi maximum working pressure
• 1/4-inch NPTF male thread for positive pressure-tight port connections
• Steel construction for durability in high-pressure hydraulic and fluid power systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for high-pressure hydraulic, pneumatic, and instrumentation tubing systems using 3/8-inch OD flareless bite-type tube connections with 1/4-inch NPTF ported components.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber following applicable system pressure and fluid compatibility requirements. Depressurize and isolate the hydraulic or fluid system completely before removing or installing any fittings. Use appropriate tube-cutting and deburring tools to ensure a clean, square tube end before seating the bite ring. Follow the fitting manufacturer's recommended assembly procedure for bite-type fittings, including proper pre-swaging or field-assembly steps, to achieve a leak-free connection.
