Posi-Gard / Vac-Gard

Low pressure rupture discs with 5-pin DIN connection and integral burst detection

This range of composite, low pressure reverse acting rupture discs are manufactured with integral burst detection. They feature a 5-pin DIN connection and are suitable for applications operating at low pressures.

Posi-Gard can withstand full vacuum, while Vac-Gard withstands up to 1 barg of back pressure. For ultra low pressures, have a look at our Milli-Gard rupture disc.

Both Posi-Gard and Vac-Gard offer non-fragmenting opening. Due to their modular content, we can offer them with bespoke designs for a broad range of non-standard specifications and applications.
