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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e T-500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 5640DC-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Designation:\u003c\/strong\u003e MK2 AER ST 3-1\/2 DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Diameter:\u003c\/strong\u003e 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Configuration:\u003c\/strong\u003e Double clamp (DC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.5917 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 022697025982\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the 5640DC-1 exhaust hose?\u003c\/strong\u003e The T-500 MK2 5640DC-1 measures 3-1\/2 inches in diameter, matching the 3-1\/2 designation in its model name.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does DC mean on the T-500 MK2 AER ST 3-1\/2 DC?\u003c\/strong\u003e DC on part number 5640DC-1 refers to the double-clamp configuration, meaning each hose connection is designed to be secured with two clamps rather than one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this exhaust hose weigh?\u003c\/strong\u003e The 5640DC-1 weighs 0.5917 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the T-500 MK2 AER ST 3-1\/2 DC?\u003c\/strong\u003e The UPC for part number 5640DC-1 is 022697025982, which can be used to confirm you are ordering the correct hose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this hose a direct replacement for my old exhaust hose?\u003c\/strong\u003e The 5640DC-1 is sized at 3-1\/2 inches in diameter, so it can replace an existing exhaust hose of the same 3-1\/2 inch diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does MK2 mean for this part?\u003c\/strong\u003e MK2 indicates this is the second revision of the T-500 hose line, part number 5640DC-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does AER ST stand for on this hose?\u003c\/strong\u003e AER ST is the style designation used in the T-500 MK2 5640DC-1 model name, denoting an Aeroquip-style hose construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many clamps do I need to install the 5640DC-1?\u003c\/strong\u003e Because the 5640DC-1 is a DC, or double-clamp, hose, two clamps per connection point are recommended for installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the part number for the T-500 MK2 AER ST 3-1\/2 DC hose?\u003c\/strong\u003e The part number is 5640DC-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 5640DC-1 be used on both port and starboard exhaust runs?\u003c\/strong\u003e The 5640DC-1 is a 3-1\/2 inch exhaust hose with no side-specific designation, so it is suited for exhaust runs sized to that diameter regardless of side.\u003c\/p\u003e","brand":"- None -","offers":[{"title":"Default Title","offer_id":49031624163547,"sku":"ATT-5640DC-1","price":32.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/ATT-5640DC-1__06534.1780061517.500.750.jpg?v=1785329068","url":"https:\/\/www.goodvibesmarina.com\/products\/t-500-mk2-marine-exhaust-hose-3-1-2-inch-aer-st-double-clamp-style-5640dc-1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
