Parker KP76457 Hydraulic Hose Swivel Adapter 5000 Psi

Product Description

The PARKER KP76457 is a hydraulic hose swivel adapter designed to connect hose ends to hydraulic systems with a rotating joint that prevents hose twist during installation and operation. Built from steel with a 9/16-18 thread and SAE ORB (O-Ring Boss) port configuration, this fitting is rated to 5,000 psi and suits high-pressure hydraulic circuits. The swivel design allows the hose to be positioned without torquing the connection, reducing stress on the hose assembly. Hydraulic system technicians and fluid power specialists install this type of adapter in mobile equipment, industrial machinery, and other hydraulic plumbing applications.

This adapter is suited for use in high-pressure hydraulic lines where a swivel connection point is required to manage hose routing. The 9 mm hose size and 9/16-18 thread make it applicable to mid-range hydraulic hose assemblies in both mobile and stationary hydraulic systems. The SAE ORB thread form provides a leak-resistant seal via an O-ring at the port face, which is the preferred configuration in many industrial and equipment OEM hydraulic circuits.

Key Features

• 5,000 psi pressure rating suitable for high-pressure hydraulic circuits
• Swivel design prevents hose twist during assembly and routing
• SAE ORB (O-Ring Boss) thread form for reliable leak-resistant port sealing
• Steel construction for durability in demanding hydraulic environments
• 9/16-18 thread size with 9 mm hose compatibility

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using 9 mm hose with a 9/16-18 SAE ORB port connection and a 5,000 psi pressure rating.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. SAE ORB fittings require a properly seated and undamaged O-ring at the port face to achieve a leak-free connection — inspect and replace the O-ring if there is any sign of damage or deformation. Follow applicable industry standards and equipment manufacturer torque guidelines for hydraulic fittings of this thread size.
