The black wall pass-through to glue – diameter 40 mm is designed for the connection of aquariums with standard or high-pressure PVC pipes of 40 mm. Made from durable ABS, it is compact and offers great space-saving, thanks to the optimization of seals and the locking nut.
For optimal installation, drill a 52 mm hole in the aquarium wall. Insert the wall pass-through ensuring the seals are properly positioned. Tighten the nut to ensure perfect sealing. The additional groove on the upper part of the wall pass-through allows for almost complete drainage of the aquarium if it is positioned on the bottom filter.
