Parker 8 C5BU-S Bite-type Tube Elbow 1/2 in Steel 5000 Psi

Product Description

The PARKER 8 C5BU-S is a flareless bite-type tube straight thread elbow designed for high-pressure hydraulic and fluid power applications. This 90-degree elbow accepts a 1/2-inch tube OD using a bite-type flareless connection and threads into ports with a 3/4-16 UN UNF straight thread. Constructed from steel, it is rated for a maximum working pressure of 5,000 psi. The 24-degree flared seat angle conforms to standard flareless fitting geometry. This fitting is installed by licensed pipefitters, hydraulic technicians, and industrial service professionals working on fluid conveyance systems where a leak-free, vibration-resistant connection is required.

This elbow is suited for use in hydraulic systems, fluid power circuits, and industrial tubing assemblies where a 90-degree directional change is needed between a tube line and a straight-thread port. It is commonly installed in mobile equipment, machine tool hydraulics, and stationary industrial systems. The straight thread port connection eliminates the risk of thread-form leak paths associated with tapered threads, making it a preferred choice in systems requiring consistent, repeatable sealing at the port face.

Key Features

• Flareless bite-type connection grips the tube without requiring a flared end
• 90-degree elbow shape routes tubing in tight or space-constrained installations
• 3/4-16 UN UNF straight thread port for reliable, non-tapered port sealing
• Steel construction rated to 5,000 psi maximum working pressure
• 24-degree flared seat angle for compatibility with standard flareless fitting systems
• 1/2-inch tube OD accommodates common hydraulic and fluid power tubing sizes

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power tube assemblies using flareless bite-type connections with a 1/2-inch tube OD and 3/4-16 UN UNF straight-thread ports.

Installation Notes

Installation of flareless bite-type fittings should be performed by a qualified hydraulic technician or pipefitter. Depressurize and de-energize the hydraulic system fully before disconnecting or installing any fittings. Use appropriate tube cutting and deburring tools to ensure a clean, square tube end before assembly, as tube end condition directly affects bite ring engagement and seal integrity. Follow the fitting manufacturer's assembly procedure for presetting the bite ring; do not substitute torque-only methods without proper pre-swage or pre-set tooling.
