Super Seal is a system additive that will find and seal leaks in refrigeration systems andalso has an eliminator to dry any moisture in the system preventing acid/waxing, dissolves blockages and frees TEVs.Super Seal is a light, low viscosity particle free liquid that is directly placed into the systemas a mist as it travels with the refrigerant and oil throughout the system, the sealant exits the leak point and react with moisture in the air this forms a low tensile crystalline structurethat creates a permanent seal.
