Parker PT-00029 Hydraulic Pipe Plug Fitting 7200 Psi

Product Description

The PARKER PT-00029 is a straight hydraulic pipe plug fitting designed to seal and cap hydraulic hose lines and port connections in high-pressure fluid power systems. Built from stainless steel, this fitting carries a maximum working pressure of 7,200 psi, making it suitable for demanding hydraulic applications where corrosion resistance and pressure integrity are critical. It features a 1/4-inch NPT and NPTF male thread in a straight configuration and is installed by licensed hydraulic technicians and pipefitters working on industrial and mobile hydraulic systems.

This fitting is used in hydraulic systems requiring a reliable threaded plug to cap off 1/4-inch hose or port connections. Its NPTF thread form creates a pressure-tight seal through thread interference, reducing reliance on sealants in many applications. Typical install scenarios include capping unused ports on hydraulic manifolds, cylinders, valves, and pumps in both industrial and mobile equipment. Each package contains 2 fittings. The fitting conforms to SAE standard 130109N and belongs to the Parker HHP series.

Key Features

• 7,200 psi maximum working pressure rated for high-pressure hydraulic service
• Stainless steel construction provides corrosion resistance in harsh fluid environments
• Male NPT and NPTF 1/4-18 thread for pressure-tight port sealing
• Straight pipe plug configuration for direct port capping without adapters
• Conforms to SAE 130109N standard
• Sold as a 2-piece package per order unit

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic systems using 1/4-inch NPT or NPTF female port connections rated to 7,200 psi, consistent with Parker HHP series hydraulic hose plug fittings.

Installation Notes

Installation is typically performed by a licensed hydraulic technician or pipefitter. Depressurize and de-energize the hydraulic system fully before removing or installing any fitting. Apply thread sealant per system requirements unless the NPTF thread-interference seal is sufficient for the application. Verify torque and thread engagement meet the system design specification and applicable fluid power codes before returning the system to service.
