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

Product Description

The PARKER 6 CBU-S is a flareless bite-type tube male elbow designed for high-pressure hydraulic and instrumentation tubing systems. This 90-degree elbow fitting connects 3/8 inch OD tubing to a 1/4 inch NPTF male thread port, achieving a rated maximum working pressure of 5000 psi. Constructed from steel, the fitting uses a bite-type compression sleeve to grip the tube without requiring flaring, making installation faster and more consistent. Licensed plumbers, pipefitters, and hydraulic technicians install this type of fitting in industrial fluid lines, mobile equipment circuits, and process instrumentation applications.

This fitting is suited for use in high-pressure hydraulic lines, pneumatic systems, and instrumentation tubing runs where a 90-degree change of direction is needed at an NPTF-threaded port. The bite-type design is commonly used in industrial machinery, mobile hydraulics, and OEM equipment assemblies. It is appropriate for both new installations and repair work where tube routing requires a right-angle transition at a male pipe connection.

Key Features

• Flareless bite-type design eliminates the need to flare tubing prior to assembly
• 90-degree elbow configuration at a 24-degree flared-angle seat
• 3/8 inch tube OD inlet with 1/4 inch NPTF male thread outlet
• Rated to 5000 psi maximum working pressure
• Steel construction for durability in high-pressure service

Compatibility

Designed as an OEM-style replacement or new-installation bite-type fitting for hydraulic and instrumentation tubing systems using 3/8 inch OD tubing and 1/4 inch NPTF threaded ports rated to 5000 psi.

Installation Notes

Installation is typically performed by licensed pipefitters, hydraulic technicians, or instrumentation mechanics. De-pressurize and isolate the hydraulic or fluid circuit completely before removing or installing any fitting. Apply thread sealant appropriate for NPTF connections and verify torque using the fitting manufacturer's recommended procedure for bite-type assemblies. Follow applicable industry codes and equipment manufacturer guidelines for high-pressure tubing system assembly.
