The ASC ENGINEERED SOLUTIONS 319902441 is a 1-inch galvanized square head plug designed to close off threaded pipe openings in plumbing, HVAC, and mechanical piping systems. Constructed from iron with a galvanized coating, this plug resists corrosion in wet and humid environments. The square head drive allows for wrench tightening into standard female threaded fittings. At 0.25 pounds, it is a compact, heavy-duty closure fitting suited for use wherever a secure, leak-free pipe end termination is required by licensed plumbers and pipefitters.
This square head plug is appropriate for residential and light commercial piping installations where threaded iron fittings are specified. Typical applications include capping unused branch outlets, isolating sections of water or gas distribution piping during rough-in, and closing test ports on mechanical systems. The galvanized finish makes it well suited for exposed or semi-exposed installations where moisture contact is expected.
Designed as an OEM-style replacement and standard fitting for 1-inch female threaded iron pipe connections in residential and commercial mechanical piping systems.
Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements. Shut off and depressurize the piping system completely before installing or removing any threaded plug. Apply appropriate thread sealant or pipe thread tape to the male threads prior to installation. Use a properly sized wrench on the square head drive and avoid overtightening, which can crack fittings or damage threads.
