The AQUALINE GPLUG-200 is a 2-inch threaded galvanized plug designed to seal open pipe ends in plumbing and water distribution systems. The galvanized steel construction provides corrosion resistance suited for both indoor and outdoor installations. This plug uses standard male pipe threads and is sized at 2 inches, making it a common fit for capping lines during pressure testing, system shutdowns, or permanent closures. Licensed plumbers and pipefitters install this type of fitting as part of routine maintenance and new construction work.
The GPLUG-200 is applicable in residential and light commercial plumbing systems where a threaded pipe end requires a secure, watertight cap. Common install scenarios include capping unused branch lines, winterizing supply systems, and sealing test ports after pressure checks. Its galvanized finish makes it suitable for use in areas exposed to moisture or moderate corrosive conditions.
Designed as an OEM-style replacement and general-use fitting for 2-inch threaded pipe systems in residential and commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before installing or removing any threaded fitting. Apply thread sealant tape or pipe dope to the male threads before tightening to ensure a leak-free connection. Do not overtighten, as this can crack fittings or damage threads.
