The Clever-Cut® inspection openings can be equipped with flat gaskets or a hygienic o-ring seal upon request. The OmgaSeal® design is particularly hygienic. It has almost zero clearance, can be cleaned wet and is microbiologically controllable. The seal is extremely robust and permanently gas- and fluid-tight. Clever-Cut® also provides you with KwickKlamp® locking mechanisms upon request. Pressure shock-proof designs are also possible.
