Parker PT-00025 Hex Plug 1-1/2 Nptf Female Thread Steel

Product Description

The PARKER PT-00025 is a steel hex plug designed for industrial pipe systems requiring a secure, leak-resistant thread seal. The plug uses a 1-1/2-11-1/2 NPTF female thread connection, which provides a dryseal fit by crushing the thread roots and crests together without relying solely on a sealant compound. This fitting is used to close off open pipe ends, ports, or manifold passages in pressurized fluid or pneumatic systems. Installation is straightforward and is typically performed by licensed plumbers, pipefitters, or industrial maintenance technicians working on fluid conveyance, hydraulic, or pneumatic systems.

This hex plug is suited for use in industrial and commercial pipe installations where open ports must be capped and system integrity maintained under pressure. NPTF thread classification meets dry-seal standards, making this plug appropriate for applications where thread-form sealing is required without relying entirely on thread sealant tape or compound. Typical install scenarios include manifold port closures, test port plugs, and branch line terminations in steel pipe systems.

Key Features

• 1-1/2-11-1/2 NPTF female thread provides a dry-seal, pressure-rated closure
• Steel construction for durability in industrial pipe and fluid system environments
• Hex drive profile allows installation and removal with standard open-end or socket wrenches
• NPTF classification meets dry-seal thread standards for reliable port closure
• Compact design suits tight manifold and inline port applications

Compatibility

Designed as an OEM-style replacement or direct-fit plug for industrial pipe systems using 1-1/2-11-1/2 NPTF female-threaded ports on manifolds, valves, and pipe assemblies.

Installation Notes

Shut down system pressure and depressurize the line completely before removing or installing any pipe plug. A properly sized wrench applied to the hex head ensures even torque distribution and reduces the risk of galling the threads. Although NPTF threads are designed to seal by thread interference, application of an appropriate thread sealant may be required depending on system pressure and fluid media. Follow applicable ASME or local piping codes for pressure ratings and installation procedures.
