WEICON leak detection spray is used for fast, convenient and reliable detection of leaks (cracks or porous areas) in pressure pipes. Leak detection spray does not form any hazardous compounds with carbon dioxide (CO2), propane, butane, acetylene, oxygen, city gas and natural gas. WEICON leak detection spray can be used wherever compressed air, natural gas or liquefied gas is used, where leaks can occur on fittings, screw connections and connections, and to ensure a high level of compressed air brake and gas line safety.
