Dispositivos de estanqueidad SEALING PLUGS

High performance at low cost: Blind SEALING PLUGS efficiently and permanently seal drilled holes. Many applications involve channels and drilled holes through which liquids and gases flow. The SEALING PLUGS reliably close and seal drilled holes and withstand operating pressures in both low and high ranges up to 500 bar. Use SEALING PLUGS to control and regulate flow. Reliable closing and sealing system for drilled holes. The SEALING PLUGS is a two-piece metal element that operates on the principle of pressure expansion or tension. The ball SEALING PLUGS operate on the pressure expansion principle. In this case, the ball is pressed into the sleeve, causing it to expand. The stem-type blind plug operates on the tension-expansion principle. In this case, the stem is pulled into the sleeve. Both closure elements feature grooves on the outside of the sleeve that cause the SEALING PLUG plugs to embed themselves in the base material when the sleeve expands. The PULLPLUG™ solution is the result of our continuous product development. The stem closure is based on the pull-expansion principle and offers numerous advantages. It uses less material and is therefore very economical. Furthermore, the PULLPLUG™ is stemless. For some of the components, we offer tools and devices from the Böllhoff process technology range.
