Parker 10143-20-20 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER 10143-20-20 is a straight male rigid fitting designed for high-pressure hydraulic hose assemblies. It features a Male NPTF threaded connection with a 1-1/4-11-1/2 thread size and is rated for a maximum working pressure of 5,000 psi. Machined from steel, this fitting accepts 1.25-inch inside diameter hose (size 20) and measures 4.08 inches in overall length. It is part of PARKER Series 43 and is intended for assembly by hydraulic technicians building or replacing hose ends in mobile, industrial, and fluid power systems.

This fitting is suited for hydraulic systems requiring a reliable, leak-resistant NPTF threaded termination at the hose end. It is commonly used in industrial machinery, mobile equipment, and fluid power circuits where high working pressures demand a rigid, steel-bodied connection. The straight profile supports direct inline routing without angular offset.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with hose assembly procedures. Depressurize and isolate the hydraulic circuit completely before disassembly or installation. Use a torque wrench sized for a 1-3/4 inch hex and follow PARKER assembly tooling guidelines for Series 43 fittings. Inspect hose ends and fitting seating surfaces for damage before crimping or assembly.
