Parker 8 Fbu-s Bite-type Male Tube Connector 1/2in 3/8 Nptf

Product Description

The PARKER 8 FBU-S is a flareless bite-type male tube connector designed for high-pressure hydraulic and fluid power applications. This straight fitting accepts a 1/2-inch tube OD and threads into a 3/8-inch NPTF port. The bite-type design grips the tube mechanically without requiring a flare, creating a reliable, leak-resistant seal rated to 5,000 psi maximum working pressure. Constructed from steel for strength and durability, it suits demanding industrial and mobile hydraulic systems. Licensed plumbers, pipefitters, and fluid power technicians install this type of connector in systems where vibration resistance and high-pressure integrity are critical.

This fitting is used in hydraulic lines, pneumatic circuits, and instrumentation tubing runs in both industrial and mobile equipment environments. It is suited for installations where NPTF threaded ports are standard and where flareless tube connections are preferred over compression or flared alternatives. The 24-degree flared angle geometry and straight fitting shape make it a common choice for routing steel tubing in tight or inline configurations.

Key Features

• Flareless bite-type design — no flaring tool required for tube prep
• 5,000 psi maximum working pressure rating
• 3/8-inch NPTF male thread for secure, pressure-tight port connections
• 1/2-inch tube OD compatibility
• Steel construction for high-strength, high-pressure service
• Straight fitting shape for inline tube-to-port connections

Compatibility

Designed as an OEM-style bite-type tube fitting for steel tubing with a 1/2-inch OD mating to 3/8-inch NPTF threaded ports in hydraulic and fluid power systems.

Installation Notes

Installation should be performed by a qualified pipefitter or fluid power technician familiar with flareless bite-type fitting procedures. De-pressurize and isolate the hydraulic or fluid circuit completely before removing or installing any fittings. NPTF threads are designed to seal on the thread form itself; use appropriate thread sealant per the system fluid compatibility and applicable codes. Do not overtighten — follow the fitting manufacturer's recommended turns-past-finger-tight procedure for bite-type connectors.
