Bursting Plugs

Typ(en): S-BS / S-BM / S-BZ

STRIKO bursting plugs of the S-BS, S-BM and S-BZ series can be installed at almost any position of a housing, e.g. of drives or hydraulic systems – if required, completely individually executable. This even makes it possible to retrofit a housing with a pressure relief device. Designed with a screw-in thread, the bursting plugs can be installed quickly and easily and – in the event of a response – be replaced. Three different product outlet designs (free blow-off, damped blow-off or threaded connection) of the bursting plugs ensure the greatest possible control when discharging the medium. A wide pressure range rounds off the versatility of STRIKO bursting plugs.
