Sprio System

The SPIRO® system sealing system is based on a profile of homogeneous EPDM rubber. The rubber gasket is located in a groove at the end of the fitting and is securely attached by means of an return edge. This design ensures that the rubber gasket is always held in its correct position. The sealing gasket must comply to our strict quality reqirements, so we have chosen EPDM rubber. This material is very resistant to ozone and UV rays, and at the same time unaffected by temperature fluctuations
