Parker 14 HP5ON-S Hex Socket Plug 5500 Psi 1-3/16-12

Product Description

The PARKER 14 HP5ON-S is a male straight thread O-ring hex socket plug engineered for use in high-pressure hydraulic and industrial fluid systems. Machined from zinc-plated steel, this plug seals a port with a maximum working pressure rating of 5,500 psi. The male thread conforms to UN/UNF-2A standards at a 1-3/16-12 thread size, and the O-ring face seal design minimizes leak paths at the port connection. Installation is performed with a 9/16-inch hex key or socket driver. Overall installed length is 0.75 inches. This fitting is used by hydraulic technicians, millwrights, and industrial maintenance professionals to cap or block off unused ports in manifolds, cylinders, valves, and hydraulic power units.

This plug is suited for stationary and mobile hydraulic systems operating at pressures up to 5,500 psi. Typical applications include blocking unused work ports on hydraulic valves, capping cylinder ports during storage or service, and sealing manifold passages in industrial machinery. The zinc-plated steel construction provides corrosion resistance in moderate-duty environments. It meets SAE standard 090109B, making it appropriate for systems requiring documented fitting compliance in industrial and OEM assembly contexts.

Compatibility

Designed as an OEM-style replacement or service plug for hydraulic valves, manifolds, cylinders, and power units with 1-3/16-12 UN/UNF-2A male straight thread O-ring ports rated to 5,500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any port plug. Inspect the O-ring for damage prior to installation and replace if cuts or compression set are present. Do not exceed the 5,500 psi pressure rating of this fitting in service.
