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.

Specification

Plastic - Temperature resistant up to 80 °C, black, matte finish.

Upper part (cap) - Polyamide (PA)

Lower part (threaded part) Polyacetal (POM)

O-Ring - Rubber NBR (Perbunan®)

Air filter PU-foam (Polyurethane) - Filtration 40 µm.
