The Oyltite Stik stops leaks without rebuilding. This remarkable product will stop leaks at gasket flanges, joints, rivet holes etc. until the next rebuild. Before using, cut off the first 5 mm of the stick and peel back outer coating. Then simply rub the Oyltite Stik vigorously into the leak area until forced into cracks and it will dry to prevent petrol, oil and water leaks. It may take a minute or so of constant rubbing to seal the leak. Can also be used as a thread sealer on assembly work. For low pressure up to 15 PSI (1BAR).
