Product Description
GN556 Breather Caps, with Two Functions
Breather caps GN 556 are used when the ventilation / breathing function is temporarily not required or desired, for instance during transport. The cap can be turned to a closed position to seal, or turned to open to breathe.
In their sealing position, the two O-rings prevent liquids and gases from leaking.
As shown in the diagram opposite, air throughput is permitted in the ventilation / breathing position.
