Company overview



ONIS is an international group whose focus is the design and manufacture of Quick-Action Line Blinds.

Quick-Action Line Blinds are the higher safety solutions which lead to save operating costs for Oil & Gas upstream & downstream critical applications. They are also the preferred way to achieve 100% positive isolation of process parts.

Since 1979, more than 10,000 ONIS Quick-Action Line Blinds have been installed in more than 40 countries worldwide.

The group operates from its design and manufacturing facility in France with regional sales offices including  the USA, the UAE, South East Asia, Germany & China.

Quick-Action Line Blinds can blind pipes in minutes with one person only and zero tools outperforming conventional figure-8, spectacle, and slip blinds.
