Parker 6-8 F5BU-S Straight Thread Connector 3/8 in 6000 Psi

Product Description

The PARKER 6-8 F5BU-S is a flareless bite-type straight thread connector designed for high-pressure hydraulic and fluid power tubing systems. It provides a secure, leak-resistant connection between metal tubing and ported components using a 24-degree flared angle bite-type sleeve mechanism rather than a flared tube end. Rated to a maximum working pressure of 6,000 psi, this fitting accommodates 3/8 inch tube outside diameter and threads into a 3/4-16 UN UNF straight thread port. The body is steel construction, suited for demanding industrial and mobile hydraulic applications. Licensed technicians and fluid power specialists install this fitting in hydraulic plumbing assemblies.

This connector is used in hydraulic systems, industrial fluid lines, and mobile equipment where flareless tube connections to straight thread ports are required. The bite-type design eliminates the need for flaring the tube end, making field assembly more straightforward. It is appropriate for both original equipment and replacement installations on systems operating at pressures up to 6,000 psi where a 3/8 inch OD tube must be connected to a 3/4-16 UN UNF threaded port.

Key Features

• Flareless bite-type design eliminates tube flaring during assembly
• Maximum working pressure of 6,000 psi for high-pressure hydraulic service
• 3/8 inch tube outside diameter compatibility
• 3/4-16 UN UNF straight thread port connection
• 24-degree flared angle sleeve geometry for positive bite and seal
• Steel construction for strength and durability in hydraulic environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3/8 inch OD tubing and 3/4-16 UN UNF straight thread ports rated to 6,000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic system completely before removing or installing any fittings. Use the appropriate tube cutter and deburring tool to prepare the tube end square and clean before inserting into the fitting. Refer to the fitting manufacturer assembly procedure and applicable fluid power standards for proper sleeve pre-set and final torque practices.
