Shaw Turn-Tite Rubber Plugs
These rubber plugs have brass T-handles for an excellent grip to hand tighten the expanding plug into a hole. The industrial-grade neoprene rubber body is ribbed for better grip and a high expansion rate (10 - 12 percent). These mechanical expansion plugs are designed to close off pipes, receptacles and open conduits which are subjected to high pressure due to the fluid present in them.
