Product Description

GN774.1 Breather Caps, Plastic, With Membrane

Breather caps GN 774.1 prevent the build up of a pressure drop over liquids in a tank.

They are used when a tank has to be rapidly emptied. The elastic membrane ensures a sufficient supply of air to prevent any vacuum build-up in the tank.

In addition, the back pressure behind the membrane will prevent the leakage and escape of any liquid in the tank to the outside, especially during transport. Even if the tank is turned upside down with the additional back pressure from the liquid, it will be sufficient to keep the outlet firmly shut.
