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.
Applications at high speed and low pressure. With O‑ring as secondary seal for sealing in the groove base. Hygienic design without undercuts. No sump formation in front of the seal. Reduced heat buildup due to special lip design. Pressureactivated seal energization. The integrated wedge prevents the sealing lip turning inside out. Very long seal life due to high abrasion resistance. Material only generates low frictional force. Sealing lip does not stick to the mating surface even after prolonged shutdown
