Pipe Plugs by COB Industries
Back to Products

COB Industries Inc, has a pipe plug/ test plug for almost every application. From 1/2" to 96" diameters and 0 PSI to 10,000 PSI, COB can answer all of your pipe plug needs. Multi-sized inflatable pipe plugs will cover a broad range of pipe sizes with a single plug. Bag Plugs provide a foreign material or gas barrier for many different pipe applications. Our mechanical wing nut style pipe plugs offer an economical way to block off or test low pressure applications through 36" in diameter. Wing nut style plugs are available in chemically resistant nylon 6 material as well as aluminum bodies.

Custom made units are made from virtually any material for temperature or chemical resistance. The Qwik Sealfast pipe test plugs provide an additional level of security when testing up to 96" diameter pipe with their internal bracing lugs. Medium Pressure Roll-Ups use an inflatable seal around a solid core to give up to 150 PSI back pressure capabilities. Disc plugs allow for testing to 15 PSI in limited distance applications. Viton, Silicon and Nitrile seals are available to chemical and high temperature applications. If we don't have it in stock you can be sure we probably made it before and can quickly and efficiently make any plug plugs or test plugs for your application. Download Product Brochure
