IP-RATING

I P rating “Ingress Protection" is the degree to which the item is protected from the environment.
Example IP65… is total protection against dust (6) and protected against low-pressure water jets from all directions.(5) (limited Ingress permitted)
Many enclosures, connectors, switches cabinets have an IP rating specified.
Our specialist gasket knowledge and material range will assist you to establish the necessary IP rating for your equipment.
