Parker PT-00103 Bite-type Male Connector 3/8 in Steel

Product Description

The PARKER PT-00103 is a flareless bite-type tube male connector designed for high-pressure hydraulic and instrumentation tubing systems. It uses a 24-degree flared angle bite-sleeve design that grips the tube OD without requiring a flare, creating a leak-resistant mechanical connection rated to 6,000 psi maximum working pressure. The fitting accepts 3/8 inch tube OD and threads into a 1/8 inch NPTF port. Constructed from steel for durability in demanding industrial and fluid-power environments, the PT-00103 has a straight fitting shape and an overall length of 1.15 inches. Licensed plumbers, pipefitters, and hydraulic system technicians typically install this type of connector in control lines and instrument tubing runs.

This connector is suited for straight-line tubing terminations at NPTF-ported valves, manifolds, cylinders, and instrumentation panels. It is commonly used in hydraulic power units, fluid control systems, and industrial process lines where tube-to-port connections must hold elevated working pressures without welding or flaring. The bite-type design simplifies field assembly and is appropriate for both original equipment installations and service replacements in industrial and mobile hydraulic applications.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• 6,000 psi maximum working pressure rating for high-pressure hydraulic service
• 3/8 inch tube OD connection with 1/8 inch NPTF male thread
• 24-degree flared angle sleeve for a secure, leak-resistant grip on tube OD
• Straight fitting shape for direct port-to-tube inline connections
• Steel construction for strength and resistance in industrial fluid-power environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and instrumentation tubing systems using 3/8 inch OD tube with 1/8 inch NPTF-ported components.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber. Depressurize and lock out the hydraulic or fluid system completely before removing or installing any fittings. Ensure the tube OD is cut cleanly and squarely and is free of burrs before inserting into the fitting body. Follow the fitting manufacturer's assembly procedure for bite-type fittings, which typically requires a specific number of turns past hand-tight to properly seat the sleeve.
