The Bilbao d400 tank seal is a precisely dimensioned rubber element intended for replacement when water leakage is detected from the 400 mm diameter filter tank.
A worn or cracked seal causes pressure losses throughout the filter circuit and reduces cleaning efficiency – timely replacement eliminates these problems.
The original component dimensions guarantee a proper fit and reliable sealing even at the operating pressure of the Bilbao filter tank.
Replacing the seal is an inexpensive alternative to purchasing an entire new filter tank.
