DN8 Coupling

The DN8 Coupling is a precision-engineered connector designed for fast, secure, and leak-free connections in pressurised or vacuum systems. Its simple push-fit mechanism ensures reliable sealing with an integrated O-ring during the coupling process, while automatically closing both sides when disconnected to prevent gas loss. Built for durability and safety, the DN8 is widely used in applications requiring tight, repeatable connections with SF₆ gas and other compatible systems.

Key Features & Benefits

Quick & secure connection – Simple push-fit design allows fast coupling without additional tools.
Leak-tight sealing – O-ring ensures pressure- and vacuum-tight performance during operation.
Automatic shut-off – Both coupling sides close automatically upon disconnection to prevent gas loss.
Temperature resistant – Standard operating range from –40 °C to +80 °C; optional version extends to –60 °C.
Durable construction – Built for reliable long-term performance in demanding environments.
System compatibility – Designed to fit with DILO connection parts for seamless integration.
