Parker PT-00066 Steel Flared Tube Reducer 5/8 in 37 Deg

Product Description

The PARKER PT-00066 is a steel flared tube reducer fitting designed for high-pressure hydraulic and fluid power line connections. It transitions between tube sizes using a 37-degree flare-to-flare end connection, with a 5/8 inch outside diameter on the tube side and a 5/8 x 1/4 inch thread configuration. Rated to 5000 psi maximum working pressure and 500 degrees F, this reducer is built for demanding industrial and fluid conveyance applications. Licensed plumbers, hydraulic technicians, and fluid power specialists install this type of fitting in systems where a secure, leak-resistant tube reduction is required.

This fitting is suited for use in hydraulic lines, fuel systems, and industrial fluid circuits where 37-degree flare connections are the specified standard. The flare x flare end design allows direct in-line installation between two flared tube ends. Its compact overall length of 1.61 inches makes it practical in tight plumbing runs. Typical applications include mobile hydraulic equipment, industrial machinery, and high-pressure fluid transfer systems requiring a reliable reducer at a tube junction.

Key Features

• Flare x flare end connections for secure, leak-resistant tube joining
• Compact design at 1.61 inches overall length

Compatibility

Designed as an OEM-style replacement or direct-fit reducer for hydraulic and fluid power systems requiring 37-degree flare tube fittings with a 5/8 inch OD tube connection conforming to SAE J514 and ISO 8434-2 specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with flared tube fitting assemblies. Depressurize and fully isolate the hydraulic or fluid system before disassembly or fitting replacement. Use appropriate flare nut wrenches to avoid distorting the flare seat. Ensure mating tube flares are properly formed and free of burrs before assembly to maintain pressure integrity.
