Parker 12 V5BU-S Flareless Bite-type Tube Fitting 3/4 in

Product Description

The PARKER 12 V5BU-S is a flareless bite-type tube fitting designed to create secure, leak-resistant connections in hydraulic and fluid power systems without requiring a flared tube end. The fitting accepts a 3/4-inch tube outside diameter and threads into a port with a 1-1/16-12 NPTF thread, providing a pressure-tight seal through the tapered thread form. This style of fitting is used in high-pressure fluid lines where flaring is impractical or where quick, reliable assembly is required. Installation is performed by licensed plumbers, hydraulic technicians, and fluid power specialists working on industrial and mobile equipment.

This fitting is suited for hydraulic systems, pneumatic lines, and industrial fluid circuits that require a flareless connection at a NPTF-ported component. The bite-type design allows the fitting sleeve to grip and bite into the tube wall during assembly, eliminating the need for tube preparation beyond cutting and deburring. Typical applications include machine tool hydraulics, mobile equipment fluid lines, and industrial process piping where NPTF ported valves, cylinders, or manifolds are used.

Key Features

• Flareless bite-type design eliminates tube flaring before assembly
• 3/4-inch tube outside diameter for compatibility with standard hydraulic tubing
• 1-1/16-12 NPTF thread provides a pressure-tight tapered thread seal
• NPTF thread form conforms to Dryseal standards, reducing reliance on sealant
• Compact, single-piece fitting suited for tight routing in hydraulic circuits

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3/4-inch OD tubing and 1-1/16-12 NPTF ported components.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed pipefitter. Depressurize and isolate the hydraulic or fluid circuit completely before removing or installing any fitting. Cut and deburr the tube end squarely before assembly to ensure the bite sleeve seats correctly. Apply thread sealant according to system requirements and tighten to the fitting manufacturer's assembly procedure for bite-type fittings.
