In Valves, Couplings & Unions

DILO couplings allow users to establish a gas-tight connection by simply securing corresponding ends together hand tight. The self-sealing design of these couplings ensure a virtually emission-free operating environment, even during connecting/disconnecting.

All couplings are temperature-resistant from -40 °C to +80 °C.
