Parker KP81351 Hydraulic Hose Fitting 90 Degree Elbow

Product Description

The PARKER KP81351 is a 90-degree elbow hose fitting designed for hydraulic fluid conveyance in medium- to high-pressure hose assemblies. Machined from steel with a male SAE threaded connection, this fitting accepts 3/8-inch (0.375-inch) inside diameter hose and threads to a 5/8-18 port. It belongs to Parker Series 43 and is intended for assembly by hydraulic technicians and industrial maintenance professionals working on mobile and stationary hydraulic systems. The 90-degree elbow geometry routes hose runs in tight or angular plumbing layouts where straight fittings would create excess bend stress or routing conflicts.

This fitting is suited for use in industrial hydraulic systems, mobile equipment, and fluid power circuits requiring a right-angle transition at the hose termination point. The 5/8-18 male SAE thread is a common port size found on pumps, cylinders, valves, and manifold blocks across a wide range of hydraulic equipment. Sold in a package quantity of four, making it practical for multi-circuit builds or repair stock.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with Parker hose assembly procedures. Depressurize and bleed down the hydraulic system fully before disconnecting or installing any hose or fitting. Use appropriate crimping or skiving equipment specified for the hose series; do not attempt to hand-tighten swaged or crimped ends. Verify thread engagement and torque to the fitting manufacturer's specifications for 5/8-18 SAE connections — reference Parker catalog TR-1H or your equipment service manual for applicable torque values.
