Opti-Gard SoLo Reverse Acting Disc

Accurate bursting in low pressure applications

Opti-Gard SoLo is an innovative, low pressure rupture disc that works reliably even in demanding process conditions.

Elfab achieves the low burst pressure capability of this reverse-acting rupture disc by combining a patented geometric shape with state-of-the-art precision manufacturing. The result is a solid metal bursting disc that operates accurately from pressures as low as 2 psig.

Install Opti-Gard SoLo in our reverse-acting rupture disc holder. We fit the disc with a magnet as standard so you can use it with Elfab’s unique, reusable, non-invasive burst detection system Flo-Tel.
