Rupture disc holder IG

 

The rupture disc holder IG can be used with both reverse and forward acting rupture discs.


The holder’s unique design guarantees that the rupture disc is always inserted correctly. A full metal clamp ensures the seal is tight. This prevents the rupture disc from being damaged and allows it to be re-used after having been removed, e.g. during an inspection.
