Parker 8-12 F5BU-S Bite-type Tube Connector 1/2 in Steel

Product Description

The PARKER 8-12 F5BU-S is a flareless bite-type tube straight thread connector designed for hydraulic and fluid power systems requiring leak-resistant, high-pressure tube connections without flaring the tubing end. Machined from steel, this straight-configuration fitting accepts a 1/2 inch tube OD and threads into ports with a 1-1/16-12 UN UNF straight thread. It is rated for a maximum working pressure of 4,500 psi, making it suitable for demanding hydraulic circuit work. The 24-degree flared angle conforms to standard bite-type fitting geometry. Hydraulic technicians and fluid power mechanics are the primary installers for this type of fitting.

This connector is used in hydraulic systems, mobile equipment circuits, and industrial fluid power applications where flareless tube connections are specified. The straight thread port end creates a pressure-tight seal against a machined seat rather than relying on tapered pipe threads, reducing the risk of cross-threading and thread-sealing compound failure. It is commonly installed in equipment that requires reliable tube-to-port connections at sustained high pressure in both stationary and mobile hydraulic applications.

Key Features

• Flareless bite-type design eliminates the need to flare tubing before installation
• 1/2 inch tube OD accommodates standard hydraulic tubing in that size
• 1-1/16-12 UN UNF straight thread port end for leak-resistant port connections
• 4,500 psi maximum working pressure rating for high-pressure hydraulic circuits
• 24-degree flared angle conforms to standard bite-type fitting geometry
• Steel construction for durability in hydraulic and fluid power environments

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems using flareless bite-type tube connections with a 1/2 inch tube OD and 1-1/16-12 UN UNF straight thread ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic familiar with bite-type fitting assembly procedures. De-energize the hydraulic system and relieve all system pressure before removing or installing any fittings. Use the appropriate hex wrench matching the 1.25 inch hex size and follow the fitting manufacturer's assembly instructions for proper sleeve bite depth, as over- or under-tightening a bite-type fitting can compromise the seal. Verify that tube OD, wall thickness, and material are compatible with the rated working pressure before returning the system to service.
