High-performance rupture disc for use

with duplex holders

Opti-Gard (High-Strength Magnet) is a technically advanced reverse-acting rupture disc specifically designed for use with 22cr and 25cr  duplex holders.

The high-strength magnet means you can still use our unique, non-invasive burst detection systems Flo-Tel and Flo-Tel XD.

Standard rupture discs will not allow this, as the duplex stainless steel is magnetic and prevents the detector from functioning correctly. Elfab’s specially developed high-strength magnet overcomes this problem and enables accurate signalling up to 140°C.
