Parker KP81289 Male Sae 37 Jic Hydraulic Hose Fitting

Product Description

The PARKER KP81289 is a male SAE 37-degree JIC rigid hydraulic hose fitting designed for use with a range of Parker hydraulic hoses in industrial and mobile fluid power systems. Constructed from steel, this straight fitting features a 3/4-16 threaded connection and accepts hoses with a 0.375 inch (3/8 inch) inside diameter, designated as hose size 6. With an overall length of 2.3 inches (58 mm), the KP81289 provides a compact, rigid termination point for hydraulic lines operating in high-pressure environments. It is installed by hydraulic system technicians and fluid power specialists in OEM and MRO applications.

This fitting is suited for use in mobile equipment, industrial hydraulic circuits, and fluid transfer systems where a reliable male JIC connection is required. The SAE 37-degree flare interface provides a metal-to-metal seal that holds up under pressure cycling and vibration. Parker lists this fitting as compatible with a broad range of their hose product lines, making it a common stock item for hydraulic assembly shops and service fleets maintaining Parker-hosed equipment.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. The JIC 37-degree flare connection requires proper flaring of the hose end to achieve a leak-free metal-to-metal seal — do not overtighten, as this can damage the flare seat. Follow applicable industry standards and equipment manufacturer guidelines for assembly and torque procedures.
