Parker PP-00337 Male Sae 37 Jic Rigid Fitting 1/4 in

Product Description

The PARKER PP-00337 is a male SAE 37-degree JIC rigid hydraulic hose fitting designed for use with 1/4-inch hydraulic hose and a 7/16-20 thread size. Constructed from steel, this fitting provides a secure, leak-resistant connection in hydraulic circuits where rigid, non-swivel termination is required. The 37-degree JIC flare seat is a widely used standard in fluid power systems, offering reliable metal-to-metal sealing under pressure. This fitting is typically installed by hydraulic system technicians and fluid power mechanics working on mobile equipment, industrial machinery, or stationary hydraulic power units.

This fitting is suited for hydraulic hose assembly applications where a male JIC termination is needed at the hose end. Common installation scenarios include connecting hoses to valves, cylinders, pumps, and manifolds in both mobile and industrial hydraulic systems. The rigid body style means the fitting does not rotate after installation, making it appropriate for fixed-position hose routing where alignment is set during assembly. Its compact size makes it practical in tight plumbing layouts.

Key Features

• SAE 37-degree JIC flare seat provides metal-to-metal sealing for hydraulic service
• Steel construction for durability in high-pressure hydraulic circuits
• Rigid male fitting body — no swivel, fixed orientation after installation
• Compatible with 1/4-inch hydraulic hose (Hose Size 4)
• 7/16-20 thread size conforms to SAE JIC standards
• Sold in package quantity of 5

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies requiring a 1/4-inch hose end with a 7/16-20 male SAE JIC rigid connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before disassembling any fittings or hose ends. Inspect the JIC flare seat and mating surface for nicks or contamination before assembly, as surface defects compromise the metal-to-metal seal. Torque to the fitting manufacturer's specifications using appropriate flare fitting wrenches — do not over-tighten, as this can distort the flare seat.
