Aqua One O-Ring for Powerhead 1000/1200 Aquis
A new main sealing ring. The sealing ring or O Ring fits around the base of the motor unit and forms a compression seal between the top and bottom parts of the filter. Over time these become less ‘springy’ and leaks can easily occur. The old seal is easily removed and once the new one is fitted you will have at least a year of use from it with no further problems.
