Parker 8-12 C5BU-S Bite-type Tube Elbow 1/2 in Steel 4000 Psi

Product Description

The PARKER 8-12 C5BU-S is a flareless bite-type tube fitting in a 90-degree straight thread elbow configuration, designed for high-pressure hydraulic and fluid power plumbing lines. The fitting accepts a 1/2 inch tube OD and threads into ports with a 1-1/16-12 UN UNF straight thread, providing a reliable metal-to-metal bite-type grip without the need for a flared tube end. Rated to a maximum working pressure of 4,000 psi, this steel fitting is suited for demanding industrial and mobile hydraulic systems. It is typically installed by hydraulic system technicians, millwrights, and plumbers working on high-pressure fluid lines.

This elbow fitting is used where a 90-degree direction change is needed in a hydraulic or fluid power circuit. Typical applications include mobile equipment hydraulics, industrial machinery, and high-pressure pneumatic or fluid transfer systems. The straight thread port connection seals against an O-ring or thread sealant at the port face, making it compatible with straight thread boss ports commonly found on pumps, valves, cylinders, and manifolds. The 24-degree flared angle is consistent with DIN-style bite-type fitting standards.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for high-pressure hydraulic and fluid power systems using 1/2 inch OD tubing with 1-1/16-12 UN UNF straight thread boss ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Use appropriate tube cutters and deburring tools to prepare the tube end for proper bite-type sleeve engagement. Follow the fitting manufacturer's assembly instructions for sleeve pre-setting and final tightening turns to ensure a leak-free connection.
