Centek's thru hull fitting with flapper valve is fiberglass and designed for marine exhaust applications. Centek Thru Hulls are constructed from compression-molded fiberglass and will not corrode like conventional fitting made from bronze or stainless steel. A weighted rubber flap helps prevent the backflow of water.
