The UNIVERSAL 3-lip ascending pipe profile gasket B-841 NT 315 (315/355) (transition sleeve/telescopic collar) is used to make a tight connection between a telescopic/smooth 315 pipe and a corrugated riser/riser 315 pipe or a corrugated riser/riser 355 pipe and a base (suitable for the DIAMIR 315 system). This product is a modernized and also a universal version of the Telescope Transition Profile Gasket ST 315 Universal For Corrugated Pipe/base (315/355).

The main difference between the almost identical products is the number of lips on the inside and outside of the gasket. This version of the universal gasket has 3 lips, which provides an additional seal between the pipe/pipe transition and the base. The gasket is placed inside or outside the notch of the shaft pipe. The gasket ensures a tight and flexible connection of the elements of the sewage and drainage network, compensates for stresses caused by weather conditions, ground conditions or environmental conditions.

The gasket is made of a flexible, durable EPDM (ethylene-propylene-diene rubber) rubber compound, and is characterized by:

- 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 - good memory of the original shape
