- resistance to organic and inorganic acids, cleaning agents, potassium and sodium alkalis
- maintaining its properties in the temperature range from -50°C to +130°C
- flexibility and susceptibility to stretching
- good memory of the original shape

hardness: 65 +/- 5° ShA

The ability to weld the gasket to the diameters of fittings from fi 63 to fi 1250.

The most popular dimentions are:

- fi 100mm

- fi 125mm

- fi 160mm

- fi 200mm

- fi 250mm
