Parker 8-12-fbu-s Male Connector 1/2 in Tube X 3/4 in Mnpt

Product Description

The PARKER 8-12-fbu-s is a Ferulok series straight male connector designed for high-pressure hydraulic and gas handling systems. It joins a 1/2-inch SAE flareless bite-type tube connection to a 3/4-inch NPTF male thread, providing a secure, leak-resistant joint without requiring flared tubing. The steel body and steel ferrule construction handle working pressures up to 4000 psi. This fitting is installed by hydraulic system technicians and industrial mechanics on fluid power lines, gas handling circuits, and related plumbing where flareless connections are specified.

This connector is suited for straight inline runs in hydraulic fluid and gas handling applications. The flareless bite-type design grips the tube wall as the ferrule seats, eliminating the need for a flaring tool on the tube end. The NPTF male thread end seals on the thread form itself, making it appropriate for high-pressure hydraulic circuits in industrial, mobile, and commercial equipment installations. A 1-1/8-inch external hex allows standard wrench access during assembly.

Key Features

• Flareless bite-type tube end accepts 1/2-inch OD tubing without flaring
• 3/4-inch NPTF male thread end provides pressure-rated dry-seal thread engagement
• Rated to 4000 psi maximum working pressure for demanding hydraulic service
• Steel body and steel ferrule for durability in hydraulic fluid and gas environments
• Straight fitting configuration for direct inline connections
• 1-1/8-inch external hex for wrench installation and removal

Compatibility

Designed as an OEM-style replacement and direct equivalent to part number 812FBUS and 8-12-FBU-S within the Parker Ferulok series of flareless hydraulic fittings.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with flareless bite-type fitting assembly procedures. Depressurize and bleed down the hydraulic system completely before removing or installing any fittings. Follow the applicable pre-swaging or nut-and-ferrule assembly steps for flareless connections as specified by Parker Ferulok assembly guidelines. Inspect the tube end for squareness and cleanliness before assembly to ensure proper ferrule bite and sealing.
