Where space is available, the Fiberglass Check Valve helps quiet exhaust noise and inhibits water intrusion. The # 316 stainless steel and Teflon® hinge mechanism will give you years of trouble-free service in either fresh or salt water. The enlarged body area allows exhaust gases to expand and cool, helping to reduce noise.
