Parker PT-00246 Steel Flared Tube Male Adapter 5/16 in

Product Description

The PARKER PT-00246 is a steel flared tube male adapter designed for high-pressure hydraulic and fluid power lines. It connects a 37-degree flared tube end to a female NPTF port, providing a leak-resistant mechanical seal without the need for sealant tape on the thread. The adapter is rated for a maximum working pressure of 6000 psi and a maximum working temperature of 500 degrees F, making it suitable for demanding industrial and mobile equipment fluid systems. The tube OD is 5/16 inches and the thread is 1/8-27 NPTF. Licensed plumbers, hydraulic technicians, and industrial pipefitters are the typical installers.

This adapter is used in hydraulic circuits, pneumatic lines, fuel systems, and refrigeration or HVAC tubing runs where a flared tube must terminate into an NPTF-ported component. It is suited to both stationary industrial equipment and mobile machinery where high-cycle dynamic pressure loads are present. The 37-degree flare angle conforms to SAE J514 and ISO 8434-2, so it seats correctly against standard JIC-style flared tube ends. The overall installed length is 1.22 inches. Sold in packages of 4.

Key Features

• 37-degree flare angle meets SAE J514 and ISO 8434-2 standards for reliable metal-to-metal seating
• Maximum working pressure of 6000 psi static and dynamic
• Maximum working temperature of 500 degrees F (260 degrees C)
• 1/8-27 NPTF thread provides a dry-seal connection that does not require additional thread sealant
• Steel construction for durability in high-pressure fluid service
• Compact overall length of 1.22 inches for tight-space installations

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic, pneumatic, fuel, and fluid power systems requiring a 5/16 inch OD 37-degree flared tube to 1/8-27 NPTF male adapter connection conforming to SAE J514 and ISO 8434-2.

Installation Notes

Installation should be performed by a qualified hydraulic technician, plumber, or pipefitter. Depressurize and drain the fluid system completely before removing or installing any fittings. The NPTF dry-seal thread is designed to form a pressure-tight joint through thread interference; inspect threads for damage before assembly and do not overtighten, as this can crack the flare seat or distort the fitting body. Verify that the mating tube end is cut square, deburred, and formed to the correct 37-degree flare angle before tightening.
