The perfect connection to the gas compartment

DILO SF6 valves and couplings

Are you looking for pressure and vacuum tight valves and couplings for SF6 gas use? DILO is the right choice! We offer the largest range of products worldwide. Whether for medium voltage switchgear, high voltage switchgear or gas-insulated lines (GIL) our products always meet your requirements.

The DILO seal principle prevents the loss of SF6 gas and moisture from penetrating the SF6 gas system. DILO couplings will eliminate the loss of SF6 gas by incorrect gas handling.
