These durable buffer caps (plug-in caps) are made of soft silicone rubber and mostly used as end caps for tubes and to fill up small holes. These caps should be placed IN the tubes/holes. For a watertight seal a slightly larger diameter will need to be chosen. For example, to fill up a 5 mm hole, choose the plug with a D of 5.45 mm.
