Parker PT-00071 Steel Flared Tube Reducer 3/4 in 37 Deg

Product Description

The PARKER PT-00071 is a steel flared tube reducer fitting designed for high-pressure hydraulic and fluid power tube assemblies. It connects two flared tube ends of differing sizes using a 37-degree flare seat geometry, reducing from a 3/4-inch tube OD connection to a 1/2-inch thread. Rated to 5000 psi maximum working pressure and a maximum working temperature of 500 degrees F, this reducer is built for demanding industrial and mobile hydraulic applications. Hydraulic technicians and fluid system specialists install this fitting in tube runs where a size transition is required without sacrificing pressure integrity.

This fitting is used in hydraulic tube systems, fluid power circuits, and high-pressure plumbing lines where 37-degree flare connections are specified. The flare x flare end configuration makes it suited for inline reducer installations in both fixed and mobile equipment. It meets ISO 8434-2 and SAE J514 standards, which are widely specified in industrial, agricultural, and construction equipment hydraulic systems. Its compact overall length of 1.79 inches allows installation in tight tube routing environments.

Key Features

• 37-degree flare seat geometry per SAE J514 and ISO 8434-2 standards
• Maximum working pressure of 5000 psi for high-pressure hydraulic service
• Maximum working temperature of 500 degrees F (260 degrees C)
• Steel construction for durability in demanding fluid power environments
• Flare x flare end connections for inline tube-to-tube reducer installations
• Compact overall length of 1.79 inches for use in space-restricted assemblies

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power tube assemblies specifying 37-degree flare connections with a 3/4-inch tube OD inlet.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with SAE J514 flare fitting assembly procedures. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. Use proper flare tube nuts and avoid over-torquing the connection, as over-tightening a flare fitting can deform the seat and cause leaks. Inspect the flare seat on both the fitting and the tube end for damage before assembly.
