Most manufacturers use a sponge core ring or solid rubber seal as a solution for IP68 small terminal boxes. These solutions both have their limitations as sponge can take a set, whilst solid rubber can displace.
As such EMI Seals & Gaskets have designed and manufactured an altogether new solution which combines the softness of sponge with the resilience of rubber. Our unique solution resists taking a set and does not displace meaning that the enclosure will retain its IP68 rating even after continual opening and re-closing and has been tested to simulate a 20 year life cycle.
This solution is currently being fitted to enclosures worldwide.
