Nissan 1217H is a high performance temperature vulcanized (RTV) silicone commonly used as a 'form in place gasket.' It has good elasticity, temperature and chemical resistance when cured. It is highly resistant to oils such as motor oil, transmission fluid or gear oil. It is not recommended for sealing engine coolant.
This is the OEM Nissan Fluid Gasket (RTV) that is found in many of their gasket kits and on your engine from the factory. This easy-to-use tube fits in the common caulk gun making application simple! Use to seal timing covers, transmissions, differentials, and more!
