Product Description

The PARKER 0188-20-20 is a hydraulic hose fitting designed for use in high-pressure fluid conveyance systems. It accepts a hose with a 1-1/4 inch (20 mm) inside diameter and features a 1-1/4-11-1/2 thread size for secure, leak-resistant connections. This fitting is a standard component in hydraulic plumbing assemblies and is typically installed by hydraulic technicians, millwrights, or industrial plumbers working on mobile or stationary hydraulic equipment. The fitting is sold individually and is suited for applications where a reliable threaded connection between hose and system components is required.

This fitting is used in hydraulic systems where 1-1/4 inch hose assemblies connect to valves, cylinders, pumps, or manifolds. It is appropriate for industrial, agricultural, and construction equipment hydraulic circuits. The 1-1/4-11-1/2 thread designation indicates a standard pipe thread profile commonly found on hydraulic ports and adapters in both mobile and stationary system configurations.
