Griffon Gas Leak Detector is a non-flammable spray for quickly and reliably finding leaks in metal and plastic pipes, couplings, valves and taps. Where there is a leak, clearly visible bubbles form so you know immediately where repair is needed. Suitable for all (flammable) gases. This 400 ml aerosol is practical for installers, maintenance technicians and DIY users checking gas, air or other pressurised lines. Spray a thin coat on the suspect area and watch for bubble formation. Use according to the instructions on the pack. Shake well before use, do not spray onto open flames or hot surfaces, and keep out of reach of children. Griffon Gas Leak Detector 400 ml is a handy aid for safe pipe checks at home or on site.
