Conduit lead through with test volume

摘要

The lead (1) has clamping devices for clamping elastomer bodies (4a, 4b) such that the clamping devices are applied at a conduit (10a) in a sealing manner due to clamping. A spacer is formed such that an inner part of the spacer freely holds test volume (12) at the clamped elastomer bodies. The test volume is pressurized via a valve body (15). The spacer is designed as an intermediate plate (11) extending transverse to a conduit direction with a through-hole considering the conduit. The spacer comprises a case i.e. tubular body, which is provided on a clamping bolt (6). The case is designed as a tubular body. The clamping devices are selected from clamping plates (5a, 5b), a raised head (6a), square end (6b) and a nut (7). An independent claim is also included for a method for manufacturing a conduit lead for constructing a sealing closure of an aperture implemented from a conduit in a wall.
