Pipe dope, or pipe joint compound, is a gooey compound used to seal the connection between threaded pipes and fittings. Because the threads in pipes and fittings still leave an air gap between the two surfaces, the gap must be filled to make it water tight (or gas tight for gas lines).
In addition to its flagship N-12 pipe, the company offers a complete line of fittings and other accessories including, Nyloplast drainage structures, and various geotextiles. ADS single wall corrugated HDPE pipe is ideal for drainage where flexibility, light weight and low cost are important. The pipe is joined with either a cleated bell, split coupler, internal coupler or snap coupler and is soil-tight.
