Uses and applications of silicone O-rings
O-rings from Siltec have a variety of applications, including:
- Sealing rings in static connections
- Colour marking rings for labelling in the food industry, pharmacy or medical technology
- Tension rings for flexible fixing of elements
- O-rings made of fluorosilicone (FMVQ) for transformers with good fuel and oil resistance
- Special O-rings for applications requiring electrical conductivity; special purity; specific colours; X-ray, metal or magnetic detectability; food grade or biocompatible material; or special temperature resistance
Possible legal standard and certificates
