Parker PT-00024 Hex Plug 1-1/4 Nptf Steel Pipe Fitting

Product Description

The PARKER PT-00024 is a steel hex plug designed to close off threaded pipe ports in industrial and commercial piping systems. It connects via a 1-1/4-11-1/2 NPTF female thread, providing a pressure-tight seal without the need for supplemental thread sealants, thanks to the NPTF dry-seal thread form. Machined from steel for durability in demanding fluid and pneumatic system environments, this hex plug is a standard component installed by pipefitters, plumbers, industrial maintenance technicians, and HVAC-R service professionals who need a reliable port closure on threaded assemblies.

This hex plug is suited for use in industrial piping, fluid power circuits, compressed air systems, hydraulic manifolds, and general-purpose pipe assemblies where NPTF-threaded closures are required. The 1-1/4-inch thread size is common in mid-to-large flow line applications across manufacturing, mechanical rooms, and process piping installations. It is sold and packaged individually, making it easy to source as a single replacement or maintenance spare.

Key Features

• NPTF dry-seal thread form provides a pressure-tight closure without additional sealant
• 1-1/4-11-1/2 female thread size fits standard mid-range pipe port applications
• Steel construction offers strength and compatibility with a wide range of fluid media
• Hex drive profile allows installation with standard open-end or socket wrenches
• Single-piece package quantity — convenient for spot replacement or maintenance kits

Compatibility

Designed as an OEM-style replacement or standard service fitting for industrial and commercial piping systems with 1-1/4-11-1/2 NPTF-threaded female ports.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or mechanical technician in accordance with applicable codes such as the IPC or IFGC. Always depressurize and isolate the piping circuit before removing or installing threaded plugs. Apply appropriate thread sealant or PTFE tape if operating conditions require additional sealing beyond the NPTF dry-seal thread engagement. Avoid over-tightening, which can distort threads or crack fittings in cast assemblies.
