The tandem configuration of type 116 allows static pressure maintenance in the critical unpressurized range and at low pressure. The security of this function is guaranteed by use of the IDG materials U95, U96 or U99 on the low pressure or atmospheric side.

The encapsulated O‑ring widens the potential applications of the O‑ring. The core of the ring is made of silicone (VMQ) or fluoroelastomer (FKM). The plastic FEP (tetrafluoroethylenehexafluoropropylene) is used for the seamless encapsulation. The particular product advantage lies in the combination of the elasticity of the O‑ring and the chemical resistance of the fluoroplastic.

Design of the housing in the form of a groove should be avoided if possible. If this is not feasible, good housing and seal cleanability must be guaranteed. The hygienic design requirements can be met by having a particularly large groove base radius, avoiding notches and having a split housing. For WIP/WOP cleaning it is important to be able to remove and replace the seal without damaging it. Given a suitable machine design, cleaning in place is also possible.
