These o-rings seal the BMW press & clip hose connections. Our o-rings are made in the USA with unparalleled quality and fit.
With trial and testing on vehicles we ourselves service, our kits optimize performance, quality, and value through the use of multiple compounds (NBR, HNBR, EPDM). All the green o-rings in our kits are peroxide cured EPDM, which we use in the most vulnerable locations for its excellent high temperature performance (150C/300F) and chemical resistance to glycol based coolants. We have transitioned all of our kits to more of these EPDM o-rings for the most vulnerable and highly stressed connections.
BMW does not offer o-rings for their press & clip hose connections and most dealerships do not stock the o-ring for the coolant temperature sensor in the lower radiator hose separately. But don't waste money buying a new sensor or unnecessarily replacing hose assemblies, all of which can last well beyond 150,000 miles. We've assembled this kit for working on customers' vehicles because We grew tired of throwing away countless serviceable parts when all that was needed were some fresh o-rings. During winter, leaks tend to develop during the cool down cycle as the already compressed rubber o-rings contract with lower ambient temperatures. Where applicable, all kits include the temperature sensor o-ring for the lower radiator hose.
