Parker 20120-4-4 Male Rigid Nptf Hydraulic Hose Fitting

Product Description

The PARKER 20120-4-4 is a straight male rigid pipe fitting designed for hydraulic hose assemblies. Built from steel with a male NPTF threaded connection, this fitting mates to the hose end and forms a secure, leak-resistant joint for hydraulic fluid lines. It carries a hose inside diameter of 0.1875 inches and a thread size of 1/4-18 NPTF. The overall installed length is 1.93 inches. This Series 20 fitting is installed by hydraulic system technicians and industrial maintenance professionals in both mobile and stationary hydraulic applications.

This fitting is suited for use in hydraulic hose assemblies where a straight, male threaded pipe connection is required at the hose end. It is commonly used in industrial equipment, mobile machinery, and fluid power systems that call for a compact, inline fitting. The 1/4-18 NPTF thread profile provides a pressure-tight mechanical seal without reliance on a secondary sealant in most applications. Compatible hose series include 201-261, 206, 221FR, 225, 235, 266, and SS25UL hoses as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and fully isolate the hydraulic circuit before removing any fittings or hose assemblies. NPTF threads are designed to seal on the thread form itself; inspect threads for damage or contamination before assembly. Torque to the fitting and port manufacturer specifications using appropriate hand tools, and verify the system for leaks before returning to service.
