The ASC ENGINEERED SOLUTIONS 318902681 is a cored, square head plug manufactured from black cast iron for use in pipe systems requiring a threaded pipe closure. The cored design allows for future connections or flow-through applications. Finished with a black coating, this plug is suited for drain, waste, and vent piping as well as general iron pipe installations. Weighing 2.17 pounds and sized at 3-1/2 inches, it is installed by licensed plumbers and pipefitters working on commercial and residential systems where a durable, threaded iron plug is required.
This plug is appropriate for threaded cast iron pipe systems in residential and commercial plumbing, drain-waste-vent configurations, and industrial pipe applications. The square head profile allows for wrench engagement during installation and removal. The cored center makes it useful where a blank-off is not required but a removable threaded closure is. Domestically produced, it meets expectations for quality control on job sites where material origin is a specification requirement.
Designed as an OEM-style replacement and standard fitting for 3-1/2 inch threaded cast iron pipe systems in plumbing and drain-waste-vent applications.
Installation is performed by licensed plumbers or pipefitters. Shut off water supply and depressurize the line before installing or removing any threaded pipe fitting. Use a pipe wrench or socket wrench sized to the square head for proper engagement. Apply thread sealant or PTFE tape to male threads per applicable IPC or local plumbing code requirements.
