5 Line Single-Size Disc Plug
The LANSAS Single Size Disc Plug has been around for more than 60 years and was the first plug manufactured by LANSAS in 1955!
The LANSAS Single Size Disc Plug has been redesigned from the ground up. It now has a wider footprint in the pipe and a bladder made with our newly reformulated rubber compound. With the addition of the RP2 Pressure Relief Valve the Disc Plug is now part of the 5-Line. These plugs are available in standard sizes up to 96” in diameter. Custom sizes are available up to 152” in diameter in virtually any shape desirable. The Standaard Disc Plugs are built as one-piece units, but these can be customized and sectioned to fit through smaller openings. Split plugs are not recommended for air testing.
