They offer much greater tolerance to heat, misalignment, engine movement and vibration than rigid connectors, with significant savings in cost, parts, labor and space.\n\n\u003cbr\u003e\u003cbr\u003eThese \u003cb\u003eStep-Up\/Reducing\u003c\/b\u003e 270V Series molded single hump exhaust bellows are made of Very High Temperature (VHT) Blue Silicone\u003cfont color=\"red\"\u003e\u003cb\u003e*\u003c\/b\u003e\u003c\/font\u003e blended with EPDM rubber (with no textile reinforcement).  This synthetic rubber blend is rated for continuous use up to 350°F (177°C) maximum.\n\u003cbr\u003eThese bellows have excellent resistance to ozone, saltwater, cold, heat, and aging.\n\u003cbr\u003eExceeds SAE J2006-R1 and ABYC \u0026amp; NMMA P-1 exhaust standards.\n\n\u003cbr\u003e270V Step-Up Exhaust Bellows provide a convenient way to connect exhaust system components with differing hose sizes. This most often happens when a component (such as a muffler) is upgraded or replaced.\n\u003cbr\u003eWhile these adapters can be used to reduce, as well as step-up, the internal size of the system, it should be noted that engine manufacturers typically don't recommend reducing the hose size, as this can increase exhaust back-pressure, which can reduce engine horsepower output.\n\n\u003cbr\u003e\u003cbr\u003e• Blue silicone\/EPDM blended rubber bellows - rated -65°F to \u003cb\u003e+350°F maximum\u003c\/b\u003e, continuous with a 10-year warranty\n\u003cbr\u003e• Available in 5 step-up sizes from 3\" x 3-1\/2\" to 6\" x 8\"\n\u003cbr\u003e• Also available in non-step-up versions; see Related Products \n\u003cbr\u003e• Inlet\/outlet cuffs are long enough to fit 2 hose clamps\n\u003cbr\u003e• Exterior color: Biue, Interior color: Blue\n\u003cbr\u003e• \u003cb\u003eNote – Part #s ending in SS come with (4) wide stainless T-bolt hose clamps.\u003c\/b\u003e\n\n\n\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eHigh Temperature Exhaust Hose Color Comparison\u003c\/b\u003e\n\u003cbr\u003e• Black exhaust hoses: made from molded, high temperature, black EPDM rubber.
