Parker 8 F5BU-S Flareless Bite-type Tube Connector 1/2 in

Product Description

The PARKER 8 F5BU-S is a flareless bite-type tube straight thread connector designed for high-pressure hydraulic and fluid power applications. Built from steel with a straight fitting shape, it accepts a 1/2 inch tube OD and threads into ports with a 3/4-16 UN UNF straight thread. The 24-degree flared angle and bite-type ferrule design create a secure, leak-resistant seal without requiring a flared tube end. Rated to 5,000 psi maximum working pressure, this fitting is suited for demanding industrial and mobile hydraulic systems where reliability under pressure is required. Licensed plumbers, hydraulic technicians, and industrial maintenance professionals are the typical installers.

This connector is used in hydraulic lines, fluid power circuits, and high-pressure tubing assemblies found in industrial machinery, mobile equipment, and similar systems. The straight thread configuration allows it to seat into straight-thread boss ports, providing a metal-to-metal seal. It is appropriate for use with compatible steel tubing in systems requiring a compact, inline straight connection at 1/2 inch tube OD.

Key Features

• Flareless bite-type design eliminates the need for pre-flared tube ends
• 5,000 psi maximum working pressure rating for high-pressure hydraulic service
• 3/4-16 UN UNF straight thread for positive, leak-resistant port engagement
• 24-degree flared angle compatible with standard bite-type fitting systems
• Steel construction for durability in industrial and mobile hydraulic environments
• Straight fitting shape for direct inline tube-to-port connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 1/2 inch OD steel tubing and 3/4-16 UN UNF straight-thread boss ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial pipefitter familiar with high-pressure fluid power systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the tube end and port threads for damage or contamination before assembly, and use appropriate bite-type ferrule installation tooling to ensure proper ferrule engagement. Follow the fitting manufacturer assembly instructions and applicable industry standards for torque and pre-swaging procedures.
