Arrangement for leak-proof, breathable feedthrough of long moldings such as cables, has diaphragm valve that is formed in ring portion, such that step perforations having disk-shaped membrane is held captive by retaining portion
摘要
<p>The arrangement comprises double nipple (3) with sealing insert and pressure screw (6) and end regions (8,10). The double nipple is located between end regions. An outwardly projecting collar (11) is extended into desired location on wall (2) and is supported with a liquid-tight breathable diaphragm valve (14). The diaphragm valve is formed in ring portion (29), such that step perforations (30) having disk-shaped membrane (32) is held captive by a retaining portion.</p>
