Technical data

A moulded gasket, made of closed cell EPDM foam, compresses between fixed body and diffuser in the closure, guarantees IP grade of protection.
They do not need a protection guard since the glass has successfully passed the resistance to impact test for high mechanical risk required by the EN/IEC 60079-0 Standard.
