These marine exhaust components include thru-hull fittings, crush sleeves, and check valves. All are designed to work in conjunction with Centek Marine exhaust systems and to withstand harsh marine environments.
Centek Marine Thru Hulls are constructed from compression molded fiberglass and will not corrode like conventional fittings made from bronze or stainless steel. Thru Hull Fittings are available with a weighted rubber flap, which helps prevent backflow of water. Centek Marine Thru Hulls are available in either white or black; all have the Lloyd’s Register Type Approval.
Centek Marine Crush Sleeves fit the inside of inlet or outlet to prevent damage due to over tightening of hose clamps. Crush Sleeves are constructed of low profile 16 gauge stainless steel. All have the Lloyd’s Register Type Approval.
Centek Marine Check Valves are designed to help prevent the back flow of water and subsequent engine damage. This provides an additional layer of safety. They are available in a wide range of sizes and colors, including any custom configuration. All Centek Marine Check Valves have the Lloyd’s Register Type Approval.
