The KPC3 model is a single layer, Kevlar constructed Pitot cover designed to provide a high level of protection to a wide range of commercial, military, unmanned and business/executive aircraft. The KPC3 is a general application, non-melting cover, and it has Sesame's proprietary waterproofing lamina installed. The lamina acts as a one-way gate for water and moisture; allowing condensation or moisture to escape but will not allow water to enter the cover from the outside.
