Parker PS1290103-12-12 Hydraulic Fitting 3/4 in 5000 Psi

Product Description

The PARKER PS1290103-12-12 is a 90-degree elbow hydraulic hose fitting that transitions from a male NPT thread to a male JIC 37-degree flare connection. Machined from steel, it carries a maximum working pressure of 5,000 psi and is sized for 3/4-inch hose with a 1-1/16-12 JIC thread. At 3.66 inches overall length and 2.27 pounds, it is a compact, heavy-duty adapter suited for high-pressure hydraulic circuits. Licensed hydraulic technicians and fluid power mechanics install this fitting as part of hose assembly work on industrial and mobile equipment.

This fitting is applied wherever a hydraulic hose must transition from an NPT-ported component to a JIC-threaded hose end at a right angle. Common installations include connecting hoses to NPT-ported pumps, valves, cylinders, and manifolds in mobile machinery, agricultural equipment, construction equipment, and industrial hydraulic power units. The 90-degree elbow geometry reduces routing stress on the hose and allows clean hose runs in tight or confined spaces.

Key Features

• 90-degree elbow body routes hose runs cleanly in confined equipment bays
• 5,000 psi maximum working pressure rated for high-pressure hydraulic circuits
• Male NPT inlet to male JIC 37-degree flare outlet for cross-thread-type connections
• 3/4-inch hose size with 1-1/16-12 JIC thread sizing
• Steel construction for durability under pressure cycling and mechanical stress
• Part of the Parker PS series hydraulic fitting line

Compatibility

Designed as an OEM-style hydraulic hose fitting replacement for 3/4-inch hose assemblies requiring a male NPT to male JIC 37-degree flare 90-degree elbow transition at up to 5,000 psi working pressure.

Installation Notes

Installation should be performed by a licensed hydraulic technician or fluid power mechanic familiar with high-pressure hose assembly procedures. Relieve all system pressure and depressurize the hydraulic circuit completely before removing or installing fittings. Apply thread sealant to the NPT threads per manufacturer guidelines and torque to the fitting manufacturer's recommended specifications for the thread size. Inspect all connections for leaks before returning the system to service.
