Parker PT-00068 Steel Flared Tube Reducer 5/8 in Od

Product Description

The PARKER PT-00068 is a steel flared tube reducer fitting designed to transition between two different tube or thread sizes in high-pressure hydraulic and fluid power lines. It features a 37-degree flare angle with flare-on-both-ends (Flare x Flare) end connections, conforming to ISO 8434-2, SAE J514, and SAE 070123 standards. With a maximum working pressure of 5000 psi and a maximum working temperature of 500 degrees F, this reducer handles demanding industrial and mobile equipment applications. The overall length is 1.48 inches and the outside diameter is 5/8 inch. This fitting is installed by hydraulic system technicians, pipefitters, and fluid power specialists working on high-pressure tube assemblies.

This reducer is suited for use in hydraulic systems, fluid power circuits, and instrumentation lines where a tube OD of 5/8 inch must be reduced to a 1/2-inch thread connection. Typical installation scenarios include mobile hydraulic equipment, industrial machinery, and OEM fluid power assemblies where a compact, reliable tube-to-tube size transition is required. The fitting ships in a package quantity of two units per order.

Key Features

• 37-degree flare angle meets ISO 8434-2, SAE J514, and SAE 070123 standards
• Rated to 5000 psi maximum working pressure for high-pressure hydraulic service
• Maximum working temperature of 500 degrees F (260 degrees C)
• Flare x Flare end connections on both ends for inline tube reduction
• Steel construction provides durability in demanding fluid power environments
• Compact overall length of 1.48 inches minimizes space requirements in tight assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic and fluid power tube assemblies requiring a 5/8-inch OD tube connection with a 5/8 x 1/2 thread reduction and 37-degree flare ends.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with 37-degree flare tube fitting assembly procedures. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Do not overtighten flare fittings; refer to the applicable SAE J514 assembly guidelines for proper torque procedures. Inspect flare seats for damage or contamination before assembly to ensure a leak-free connection.
