Product DescriptionThe APPLETON PLG-250S is a square head pipe plug designed to seal threaded pipe openings in plumbing, conduit, and industrial piping systems. At 2.5 inches, this plug threads directly into a matching female fitting to cap off unused ports, test points, or dead-end lines. Square head plugs are preferred in trade work where a wrench or socket must be used for installation and removal, providing a secure mechanical advantage over slotted or hex socket styles. Licensed plumbers, pipefitters, and industrial maintenance technicians routinely specify square head plugs for their reliability in high-torque applications.The PLG-250S suits a wide range of applications including drainage, waste, and vent piping, compressed air systems, hydraulic lines, and electrical conduit work where threaded closures are required. The 2.5 inch size fits standard pipe threads at that nominal size, making it a common choice for both new installation and repair work in commercial and industrial settings. It is appropriate for use wherever a durable, wrench-driven threaded plug is needed to close off an active or inactive pipe port.Key FeaturesSquare head design allows secure installation and removal with a standard wrench or socket2.5 inch nominal size fits standard threaded female fittings at that pipe sizeThreaded construction provides a leak-resistant mechanical seal on pipe portsSuitable for use on drainage, compressed air, hydraulic, and conduit applicationsCompatibilityDesigned as an OEM-style replacement or new-installation pipe plug for standard 2.5 inch threaded female pipe fittings across plumbing, industrial, and conduit applications.Installation NotesInstallation should be performed by a licensed plumber or qualified pipefitter.
