Parker 12 Fbu-s Flareless Bite-type Male Connector Steel

Product Description

The PARKER 12 FBU-S is a flareless bite-type tube male connector designed for high-pressure hydraulic and fluid power systems. It uses a 24-degree flared seat and a bite-type ferrule to create a secure, leak-resistant connection without requiring tube flaring. The connector features a 3/4 inch NPTF male thread on one end and accepts 3/4 inch outside diameter tubing on the other. Rated to 4,000 psi maximum working pressure, this straight fitting is built from steel for durability in demanding industrial and mobile hydraulic applications. Plumbers, pipefitters, and hydraulic system technicians install this type of fitting in high-pressure lines.

This fitting is suited for use in hydraulic systems, fluid power lines, and industrial plumbing installations where flareless tube connections are required. It is appropriate for both stationary and mobile hydraulic equipment. The NPTF thread provides a pressure-tight mechanical seal on the port side, making it a common choice for connections into pumps, valves, cylinders, and manifold blocks. The straight body configuration is used where inline tube-to-port connections are needed without directional offset.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• 4,000 psi maximum working pressure rating for high-pressure hydraulic service
• 3/4 inch NPTF male thread provides a pressure-tight port connection
• Accepts 3/4 inch OD tubing for a secure ferrule-style grip
• 24-degree flared seat angle for positive seating
• Steel construction for strength and compatibility with hydraulic fluid environments

Compatibility

Designed as an OEM-style flareless bite-type fitting for use in hydraulic and fluid power systems requiring 3/4 inch NPTF port connections with 3/4 inch OD tube.

Installation Notes

Installation is typically performed by licensed pipefitters or hydraulic system technicians. Depressurize and drain the hydraulic system completely before removing or installing any fittings. Ensure tubing is cut square and deburred before inserting into the fitting body to allow the ferrule to seat correctly. Torque the nut to the fitting manufacturer's published specifications for the tube size and material being used.
