Parker 14 P5ON-S Hex Plug 1-3/16-12 Male Thread

Product Description

The PARKER 14 P5ON-S is a male straight thread O-ring hex plug designed to seal and cap hydraulic and industrial fluid lines under high-pressure conditions. Manufactured from zinc-plated steel, it provides corrosion resistance suitable for demanding shop and field environments. The plug features a 1-3/16-12 male straight thread with an O-ring seating surface, which creates a reliable, leak-resistant seal without relying solely on thread interference. Rated to 5500 psi, it is installed by hydraulic technicians, millwrights, and fluid power specialists working on industrial machinery, mobile equipment, and hydraulic power units.

This plug is used to close off ports on hydraulic manifolds, cylinders, valves, and fittings where a straight thread O-ring connection is specified. It is suited for both OEM assembly and field service applications where a secure, pressure-rated port closure is required. The 1-3/8 inch hex drive allows standard wrench installation in confined spaces. Its zinc-plated finish makes it appropriate for general industrial and mobile hydraulic environments where moderate corrosion exposure is expected.

Compatibility

Designed as an OEM-style replacement or service plug for hydraulic systems and industrial fluid power components that specify a male straight thread O-ring port connection with a 1-3/16-12 thread size.

Installation Notes

Installation is performed by qualified hydraulic technicians or fluid power specialists. Depressurize and isolate the hydraulic circuit fully before removing or installing any port plug. Inspect the O-ring for damage before installation and ensure the mating port face is clean and free of burrs to achieve a proper seal. Follow applicable fluid power system standards and equipment manufacturer torque guidelines when tightening.
