The turbo outlet is one size, your intercooler end tanks another, the throttle body inlet something else again. A transition coupler, or reducer coupler if you grew up calling it that, steps between two pipe sizes in a single molded piece, and these SpeedFactory units do it with the same construction as their straight couplers: built for boost, not for the shelf at the hardware store.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eEach coupler is molded silicone reinforced with four plies of polyester, manufactured to the SAE J20 specification that OEM charge-air and coolant hoses are held to. The continuous temperature rating runs -76°F to +376°F, enough to live directly on a turbo or supercharger outlet, and burst pressure is over 200 PSI. That burst number is a safety ceiling rather than a working target, and it means the coupler is never the component that lets go at full boost. The molded taper steps smoothly between sizes instead of forcing a straight coupler over mismatched pipes, which is how you get a coupler that seals evenly and doesn't stress-crack at the clamp line.\u003c\/p\u003e\n\u003cp\u003eLike the rest of the SpeedFactory coupler line, each one is 3 inches long, comes in black with a white printed logo, and wears a slick outer coating that wipes clean instead of collecting engine bay grime.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSilicone, 4 ply polyester reinforced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStandard\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSAE J20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTemperature rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-76°F to +376°F continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBurst pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOver 200 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLength\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBlack with white logo, slick easy-clean outer coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eAvailable Sizes\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eMfg Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\" to 2.5\"\u003c\/td\u003e\n\u003ctd\u003eSFR-03-011\u003c\/td\u003e\n\u003ctd\u003eSF-03-011\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\" to 3\"\u003c\/td\u003e\n\u003ctd\u003eSFR-03-012\u003c\/td\u003e\n\u003ctd\u003eSF-03-012\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2.5\" to 2.75\"\u003c\/td\u003e\n\u003ctd\u003eSFR-03-013\u003c\/td\u003e\n\u003ctd\u003eSF-03-013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\" to 3.5\"\u003c\/td\u003e\n\u003ctd\u003eSFR-03-014\u003c\/td\u003e\n\u003ctd\u003eSF-03-014\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3.5\" to 4\"\u003c\/td\u003e\n\u003ctd\u003eSFR-03-015\u003c\/td\u003e\n\u003ctd\u003eSF-03-015\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eUniversal. Match each end of the coupler to the outside diameter of the pipe it joins, so a 3\" to 3.5\" transition mates a 3 inch OD pipe to a 3.5 inch OD pipe. The odd-looking 2.5\" to 2.75\" size exists for a reason: plenty of OEM turbo Honda piping and some intercooler end tanks land on 2.75, and jamming a 2.5 straight coupler over one is the leak you chase for a month. If both pipes are the same size, grab a straight coupler instead, and if the joint needs to turn a corner, an angled coupler beats forcing a straight one into a bend.\u003c\/p\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eWhat to Know Before You Buy\u003c\/h3\u003e\n\u003cp\u003eA reducer needs two clamp sizes, one for each end, so order T-bolt clamps to match both diameters rather than assuming one size fits the pair. T-bolts over worm-gear clamps on anything boosted, since worm gears bite unevenly into silicone and are the usual reason a charge pipe lets go. Seat each clamp fully on its end of the coupler, recheck torque after the first few heat cycles, and the joint is done for the life of the build.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n Universal \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\nWall Thickness: 4-Ply Polyester Reinforced \u003cdiv\u003eTemperature Rating: -76 degrees F to +376 degrees F \u003c\/div\u003e\n\u003cdiv\u003eMaterial: Silicone \u003c\/div\u003e\n\u003cdiv\u003eHose Length: 3\" \u003c\/div\u003e\n\u003cdiv\u003eType: Straight Transition  \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eID size options:\u003c\/div\u003e\n\u003cdiv\u003e2\" to 2.5\"\u003c\/div\u003e\n\u003cdiv\u003e2.5\" to 2.75\"\u003c\/div\u003e\n\u003cdiv\u003e2.5\" to 3\"\u003c\/div\u003e\n\u003cdiv\u003e3\" to 3.5\"\u003c\/div\u003e\n\u003cdiv\u003e3.5\" to 4\"\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"SpeedFactory","offers":[{"title":"2\" to 2.5\"","offer_id":45918277632034,"sku":"SFR-03-011","price":18.94,"currency_code":"USD","in_stock":false},{"title":"2\" to 3\"","offer_id":45918277664802,"sku":"SFR-03-012","price":18.94,"currency_code":"USD","in_stock":false},{"title":"2.5\" to 2.75\"","offer_id":45918277697570,"sku":"SFR-03-013","price":18.94,"currency_code":"USD","in_stock":false},{"title":"3\" to 3.5\"","offer_id":45918277730338,"sku":"SFR-03-014","price":18.94,"currency_code":"USD","in_stock":false},{"title":"3.5\" to 4\"","offer_id":45918277763106,"sku":"SFR-03-015","price":18.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/speedfactory-silicone-straight_gtdb.jpg?v=1783543570","url":"https:\/\/www.hybrid-racing.com\/products\/speedfactory-silicone-straight-transition-couplers","provider":"Hybrid Racing","version":"1.0","type":"link"}
