Mayline 2500

Self-sealing liquid

Self-sealing liquid for heating installations with daily leakage of up to 2500 litres

Mayline 2500 seals leaks of up to 2500 litres per day. The self-sealing liquid is based on the principle of providing a mechanical seal from the outside. Mayline 2500 only functions in the presence of oxygen and is suitable for all materials currently in use (synthetic and metallic). The product can even be used in open expansion tank systems.
