DILO has been a manufacturer of valves and accessories for SF6 switchgear for more than 35 years. Our SF6 couplings are used in SF6 switchgear all over the world. Due to their reliability, quality and durability they belong to the gas connections which are used most in SF6 switchgear.

The advantages of the DILO coupling system are as follows

• self-closing coupling system with metal to metal seal principle in the form of tongue and groove
• pressure and vacuum tight
• applicable up to PN64 bar
• operating temperature range: -40°C to +80°C
• can be loosened and re-connected as often as desired with the same high level of gas tightness
• available in brass, aluminium and stainless steel

All components were specially designed for the application of SF6-gas. Besides our gas handling and measuring devices, SF6 valves and couplings complete our range of products for the handling of SF6-gas.
