Parker 10743-20-20 Female Swivel Fitting 1-1/4 in Npsm Steel

Product Description

The PARKER 10743-20-20 is a straight female swivel fitting designed for use with hydraulic hose assemblies in demanding fluid-power applications. Built from steel with a threaded NPSM connection, this fitting accommodates a hose inside diameter of 1.25 inches (hose size 20) and measures 3.28 inches overall in length. It belongs to Parker's Series 43 fitting line and is intended for installation by hydraulic technicians and fluid-power specialists working on industrial, mobile, or OEM hydraulic systems. The swivel design allows the hose to be positioned without twisting during assembly, reducing installation stress on the hose end.

This fitting is suited for high-pressure hydraulic hose assemblies in both industrial and mobile equipment environments. The 1-1/4 inch NPSM thread and straight body configuration make it a practical choice for return lines, pressure lines, and routing applications where a fixed-end fitting would create hose twist. It is compatible with a broad range of Parker hydraulic hose series as listed in the compatibility section below.

Installation Notes

Installation should be performed by a qualified hydraulic technician following applicable fluid-power safety standards.

Do not over-torque NPSM threaded connections; follow the hose and fitting manufacturer assembly guidelines for proper make-up.
