Use of an adapter ring to be inserted into a pipe element of a lead-through for conduits

摘要

The adapter ring (1) has outside wall aligned on tubular element inner wall (46) while releasing one of limited passage opening of adapter ring inner wall in a press seal used with an elastomeric portion. The elastomeric portion is clamped to adapter ring inner wall and is arranged as separate component of ring, such that the inner wall is compressed to line direction against tubular element as a result of expansion of elastomeric portion and is held in passage opening. The adapter ring is made of ethylene propylene diene monomer rubber (EPDM) and thermoplastic elastomer (TPE).
