This series is shown on drawing 30057. Overall length 10.00mm. Seal mechanisim is a chamfer o-ring seal between the side and bottom face of the port. Port drawing these bursting discs is drawing 30125.
Customers have asked us whether repeated pressurisation affects the foil and therefore whether the burst disc can still be relied on to rupture at the target burst pressure after multiple use. Benoil burst discs are designed for single use and therefore recommended practice is to use the discs once only.
