Parker 20120-6-6 Male Rigid Pipe Fitting 3/8-18 Nptf

Product Description

The PARKER 20120-6-6 is a male rigid pipe fitting designed for hydraulic hose assemblies in industrial and mobile hydraulic systems. This straight fitting features a 0.3125 inch inside diameter and a 3/8-18 male NPTF threaded connection, providing a pressure-tight seal without the need for supplemental sealant on properly prepared threads. Constructed from steel, this Series 20 fitting is built to handle the mechanical stress and fluid pressure demands common in hydraulic plumbing work. It is installed by hydraulic technicians and maintenance professionals who require reliable, leak-free hose-to-fitting connections in demanding service environments.

This fitting is suited for use in both stationary and mobile hydraulic systems where a straight male NPTF connection is required at a hose end. It is compatible with Parker hose lines including the 201-261, 206, 221FR, 225, 235, 266, and SS25UL series hoses. The threaded connection style makes it appropriate for integration into manifold ports, pumps, cylinders, and valve blocks that accept 3/8-18 NPTF male fittings. Size 6 hose designation corresponds to the 0.3125 inch inner diameter bore, which aligns with standard hydraulic hose sizing conventions.

Compatibility

Designed for use with Parker 201-261, 206, 221FR, 225, 235, 266, and SS25UL series hydraulic hoses with a size 6 (0.3125 inch ID) hose configuration.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and lock out the hydraulic system completely before removing or installing any fittings. NPTF threads rely on thread-form interference for sealing, but inspect threads carefully and use appropriate thread sealant if required by the system design or applicable standards. Torque to the system or hose manufacturer specifications and verify for leaks before returning the system to service.
