Tadpole are gaskets composed of a bulb, full or empty, and a tongue. Flexible, they can be used to seal or caulk empty spaces. The combinations of the bulbs and tongues are countless. The bulb, simple, central or double, can have an inner core of fiberglass, ceramic, stainless steel wire cable or inconel wire cable. Referring to the application and surrounding environment, we will cover the bulb with the most performing fabric (see Fabrics section for available textiles). We can use a cloth or a metallic mesh that can also be coated or treated with silicone, PTFE, neoprene or vermiculite.

The combinations are diverse, each with its own qualities : the following four factors need to be analyzed in order to choose the perfect tadpole, the temperature, the abrasion resistance and the shape.
