The Eastman 43435 is a 3 in test plug designed for DWV testing that creates a temporary seal in pipe openings. It uses a rubber plug body with metal tightening hardware, including a metal plate and wing nut, to mechanically seal inside the pipe for pressure checks and system testing. A galvanized steel flange and rubber gasket enhance the seal, and compact dimensions fit 3 in nominal openings. Typical applications include plumbing, DWV system verification, and temporary pipe closure during repairs.
