The Mishimoto Silicone Oil Cooler Hose (MMHOSE-392-21OC) replaces the factory hose with a single continuous silicone piece engineered to hold its shape through the bend, eliminating the failure mode at its source rather than patching around it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDirect replacement for the failure prone factory oil cooler hose on the Rubicon 392\u003c\/li\u003e\n\u003cli\u003eSmooth internal taper eliminates the pressure pockets and flow restriction created by the factory plastic joiner\u003c\/li\u003e\n\u003cli\u003eEmbedded fiber reinforcement resists expansion and collapse under sustained pressure and heat\u003c\/li\u003e\n\u003cli\u003eSingle continuous silicone construction removes the OEM step change where the original hose splits\u003c\/li\u003e\n\u003cli\u003eWorm gear clamps included for a secure, field serviceable connection at each end\u003c\/li\u003e\n\u003cli\u003eBacked by the Mishimoto Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eThis Part Fits\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2026\u003c\/td\u003e\n\u003ctd\u003eJeep\u003c\/td\u003e\n\u003ctd\u003eWrangler\u003c\/td\u003e\n\u003ctd\u003eRubicon 392\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eMishimoto\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eMMHOSE-392-21OC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e840197727287\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eSilicone with embedded fiber reinforcement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eSingle piece, continuous internal taper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardware Included\u003c\/td\u003e\n\u003ctd\u003eWorm gear clamps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eDirect fit, no drilling or cutting required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eMishimoto Lifetime Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1x Mishimoto Silicone Oil Cooler Hose\u003c\/li\u003e\n\u003cli\u003eWorm gear clamps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout Mishimoto\u003c\/h4\u003e\n\u003cp\u003eMishimoto designs and engineers performance cooling components in house, from silicone hoses to radiators and oil coolers, with a focus on solving the specific failure points that stock parts run into under real driving conditions.
