T-500 MK2 Marine Exhaust Hose 3-1/2 Inch AER ST Double Clamp Style 5640DC-1
T-500 MK2 Marine Exhaust Hose 3-1/2 Inch AER ST Double Clamp Style 5640DC-1
The T-500 MK2 AER ST 3-1/2 DC, part number 5640DC-1, is a 3-1/2 inch marine exhaust hose built for wet exhaust routing on inboard and sterndrive engines. It is identified by its MK2 revision and AER ST style designation, indicating an Aeroquip-style hose construction intended to handle the flex demands of a marine exhaust run, and its DC configuration marks it for double-clamp installation at each hose connection for a secure, leak-resistant seal. At 3-1/2 inches, it is sized for exhaust systems specifying that diameter, and the hose weighs 0.5917 pounds. This part carries UPC 022697025982 for easy verification when ordering. Boat owners replacing a cracked, hardened, or leaking exhaust hose in this diameter can use the 5640DC-1 as a direct-size replacement, provided the existing hose is also 3-1/2 inches in diameter. As with any wet exhaust hose, proper double-clamping at both ends of each connection point is recommended to prevent water intrusion and exhaust leaks.
