Centek Thru Hull Fittings With Flapper Cover

Centek Thru Hull Fittings With Flapper Cover

Centek Thru Hulls are constructed from compression molded fibreglass and will not corrode like conventional fittings made from bronze or stainless. The weighted rubber flap helps the prevention of backflow of water. The smooth, resin rich ID assures minimal flow restrictions to exhaust gases and cooling water flowing through the tubing. 

Vernatube is a resin impregnated glass filament tubing wound exclusively with a new fire retardant resin formulated for high temperature applications. Centek uses the fire retardant Vernatube to fabricate many of the basic components used to manufacture our wet marine exhaust systems. Centek Vernatube exceeds values for the class of materials designated as "self-extingushing".
