The rubber reducer (in-situ insert/fitter's socket/drainage chamber gasket/in-situ gasket/rubber insert/in-situ/three-lip gasket) fi 315 insitu SR (315/326) is intended for making additional connections of smooth-walled and corrugated casing pipes with a diameter of 315mm. The insitu gasket seals the transition between the pipe and the connection made in plain pipes, shaft pipes, tanks, separators, water meter wells, telecommunication wells, power wells, sewage wells and all concrete tanks. In order to embed the gasket, you need to cut a hole with a diameter 326mm.

- high resistance to aging and weather conditions, ozone and UV radiation
- 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
