GASKET SEALER (GERMAN ELRING). Contains 75 grams. This sealer works so nicely I decided to add it to our list of high performance items. We started using Curil years ago on Porsche 911 engines (which are prone to oil leakage). From that moment on, oil leakage problems were greatly reduced. It's non-hardening and easy to use. Because it’s sticky and not slippery (like silicone sealer), it doesn’t cause gaskets to slip. The new non-hardening Curil T2 is not only easier to use Because of its chemical structure, it is also complete Solvent free. Since no solvent is used, no ventilation time is necessary. For this reason, the yield has also increased compared to its predecessor versions.
