Parker PT-00077 Steel Flared Tube Reducer 1-1/4 in Od

Product Description

The PARKER PT-00077 is a steel flared tube reducer designed to transition between two different tube sizes in high-pressure hydraulic and fluid power lines. Featuring a 37-degree flare angle on both ends, this fitting connects flare-to-flare and accommodates a 1-1/4 inch tube outside diameter with a 1-1/4 x 3/4 inch thread configuration. It is rated for a maximum working pressure of 4000 psi, making it suitable for demanding industrial and mobile hydraulic applications. Licensed technicians and fluid power specialists install this type of fitting during system assembly, maintenance, or line modification work.

This reducer is used in hydraulic systems requiring a tube size transition while maintaining a secure, leak-resistant flared connection. It is appropriate for both stationary industrial equipment and mobile machinery where high-pressure fluid lines must be routed through different tube diameters. The 37-degree JIC flare end connection style is a widely adopted standard in hydraulic and pneumatic plumbing across industrial, construction, and heavy equipment applications.

Key Features

• 37-degree flare angle on both ends for a reliable metal-to-metal seal
• Rated to 4000 psi maximum working pressure for demanding hydraulic service
• Steel construction provides durability in high-pressure fluid environments
• Flare x Flare end connections on both sides simplify inline tube transitions
• 1-1/4 inch tube OD with 1-1/4 x 3/4 inch thread for size reduction in a single fitting

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems using 37-degree JIC flare connections with 1-1/4 inch tube outside diameter lines.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Use appropriate flare fitting wrenches to avoid distorting the flare seats, and inspect both flare seats for nicks or debris before assembly. Follow applicable industry standards such as SAE J514 for 37-degree flare fitting installation procedures.
