Silicone cowl ventilator with red interior, ring Ø 75 mm.
Silicone rubber is an inorganic synthetic material. While silicone rubber looks and feels like organic rubber, it has a completely different structure to other elastomers. This structure gives silicone rubber a very flexible feel as well as providing a material that has very small changes in dynamic characteristics over a wide range of temperatures. Silicone has a typical service temperature range between –100 °C and +200 °C. Silicone rubber has many excellent mechanical qualities, but its greatest advantage is that it will not discolor in UV light. The ring nuts and mating deck flanges are made of hard plastic The cowl ventilators can revolve and are removable. No tools are required, the ring nut can be loosened easily by hand. A Monel mosquito screen and a stainless steel (AISI 316) cover plate to close off the cowl ventilator, can be supplied as an option.
