The PARKER PT-00393 is a steel flared tube nut designed for use with 1/2 inch outside diameter tubing and a 37-degree flare angle. This fitting nut threads onto a mating flare fitting to secure and seal hydraulic or fluid lines at the flare connection. It is rated for a maximum working pressure of 7,500 psi and a maximum working temperature of 500 degrees F, making it suitable for demanding fluid and hydraulic system applications. Installation is performed by licensed plumbers, HVAC technicians, hydraulic system mechanics, and other trades working with flare-end tube assemblies.
This tube nut is suited for use in high-pressure hydraulic lines, refrigeration and HVAC tubing circuits, fuel systems, and industrial fluid transfer assemblies where a 37-degree JIC-style flare connection is specified. It is compatible with 1/2 inch OD tubing in any installation requiring a standard 37-degree flare end connection. Sold in packages of 5, it is a practical stocking item for service vehicles and shop inventories.
Designed for use with 1/2 inch OD tubing flare assemblies requiring a 37-degree flare angle, conforming to ISO 8434-2 and SAE J514 standards.
Installation should be performed by a qualified technician familiar with flare-type tube fittings and applicable codes. Always depressurize and isolate the fluid circuit before disassembling or assembling flare connections. Use the appropriate flare nut wrench to avoid rounding the fitting; do not use pliers or adjustable wrenches on precision flare nuts. Verify that the mating tube end is properly flared to the correct 37-degree angle before torquing the nut.
