Parker PT-00028 Hydraulic Pipe Plug 1/8-27 Npt Stainless

Product Description

The PARKER PT-00028 is a straight, male NPT/NPTF threaded pipe plug fitting designed for hydraulic hose and piping systems operating at high pressure. Built from stainless steel, this fitting provides corrosion resistance in demanding fluid power environments. It carries a maximum working pressure of 7,200 psi and threads into a 1/8-27 NPT port, making it a compact but capable sealing component. With an overall length of 0.3 inches, it fits in tight plumbing configurations without clearance issues. Hydraulic technicians and fluid power specialists install this type of plug to cap off unused ports, isolate circuit branches, or seal test points during system commissioning or maintenance.

This fitting is suited for hydraulic systems in both industrial and mobile equipment applications where stainless steel is required for corrosion resistance or sanitary considerations. The 1/8-27 thread size corresponds to a 1/8 inch nominal pipe diameter, commonly found on manifolds, cylinders, valves, and pump housings. Its straight configuration allows direct port entry without angled adapters. The fitting ships in a package quantity of two, which suits bench stock or field service kit use.

Key Features

• Maximum working pressure rated at 7,200 psi for high-pressure hydraulic service
• Stainless steel construction resists corrosion in wet, chemical, or washdown environments
• Male NPT and NPTF compatible thread form provides a reliable tapered thread seal
• Straight shape allows direct port installation without offset adapters
• Compact overall length of 0.3 inches minimizes protrusion in tight manifold layouts
• Meets SAE 130109N standard for hydraulic fittings

Compatibility

Designed as an OEM-style hydraulic pipe plug fitting for 1/8-27 NPT and NPTF threaded ports in fluid power systems. Part of the Parker HHP series of hydraulic hose fittings.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist familiar with NPT tapered thread sealing practices. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Apply an appropriate thread sealant compatible with the system fluid; do not use PTFE tape on NPTF ports unless specified by the system designer. Torque to the fitting manufacturer or system OEM specification for the port size and material — do not over-torque stainless steel threads into softer port materials.
