Service equipment – FAQ - WIKA Canada 6 gas is a climate-damaging greenhouse gas. 1 kg of SF 6 gas corresponds to approx. 23 tonnes of CO 2. For this reason, leakage into the atmosphere must be avoided and the use of special equipment is mandatory. Due to the design and the special self-closing valves installed in WIKA SF 6 handling equipment, gas loss can be reduced to a minimum.
