• UPC   705333510010
• RKX set of 2 premium coolant line quick connector O ring seals. Direct replacement compatible with most VW & Audi quick disconnects commonly used for heater core connections and various other connections. The dealer does not sell this as a spare part! They want to sell you an entire hose! Made from our proprietary military grade highly saturated nitrile rubber. These seals are designed to be tougher and more chemical resistant than OEM. One of the biggest problems with these seals is the type of rubber VAG uses. In order to save money they have opted for a rubber that is not resistant to many chemicals found in and around the engine which prematurely compromise the seal and cause coolant leaks. Includes: 2 - RKX premium highly saturated nitrile O rings Compatible with Volkswagen and Audi: Jetta, Beetle, Golf, Passat, Touareg, A3, A4, A5, A6, A7, A8, TT, TTRS, TTS, S3, S4, S5, S6, S7, S8, Q5, Q7 These O rings will fit most heater core / coolant flange quick disconnect couplings used from 2000 - 2022 The inside diameter of these connections will measure approximately 29mm.
