Parker 10126-4-4 Hydraulic Hose Male Rigid Fitting

Product Description

The PARKER 10126-4-4 is a male rigid hydraulic hose fitting designed for connecting 3/16-inch hydraulic hose to threaded ports using a 1/4-18 male NPTF thread. Constructed from steel, this fitting provides a secure, permanent-style connection suited for high-pressure hydraulic circuits. The male NPTF thread form creates a pressure-tight mechanical seal by thread interference, reducing the need for additional sealant in properly torqued connections. Hydraulic technicians and fluid power specialists install this fitting when building or repairing hydraulic hose assemblies in industrial, agricultural, and mobile equipment applications.

This fitting is suited for use in hydraulic systems that require a rigid, non-swivel connection at the hose termination point. It accommodates 3/16-inch hydraulic hose and mates to female NPTF or compatible NPT-threaded ports. Typical installation scenarios include hydraulic power units, mobile machinery, and fluid transfer lines where a straight, fixed-orientation connection is required. The steel construction supports use in demanding service environments common to industrial and field hydraulic work.

Key Features

• Male NPTF thread form provides pressure-tight interference fit seal
• Fits 3/16-inch hydraulic hose with a hose size designation of 3
• 1/4-18 thread size for compatibility with standard NPTF ported components
• Steel construction for durability in high-pressure hydraulic circuits
• Rigid fitting design maintains fixed hose orientation after assembly

Compatibility

Designed as an OEM-style rigid hose fitting for 3/16-inch hydraulic hose assemblies terminating to 1/4-18 NPTF threaded ports in hydraulic systems.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. NPTF threads rely on thread-form interference for sealing — inspect threads carefully before assembly and apply thread sealant only if required by the system specification. Do not overtighten, as this can damage the NPTF thread form or fitting body.
