Not to get close

I have the filter installed as a pre-filter in front of the steam jet and fortunately this is in a hall with a floor drain, otherwise it would already several times "land under" been. The water pressure is about 6 bar.

Problem: The original seal between the filter base and glass housing is too soft (silicone material?) And is constantly being pushed out. Once I have the original seal replaced by a more solid O-ring, the situation has improved somewhat, but turned at this point out another design flaw: The sealing surface on the blue filter base is flat smooth, designed so without boundary, so that the O-ring by laterally exterior can find no support and is forced out of the water pressure. Consequence: water games
