  • Für Sparks M12-Lambdastopfen, Artikel TAPPO017.
  • Spark-Artikelnummer ROND12X18R.

Warum Kupfer

Kupfer ist weich genug, um sich in die Unebenheiten eines Stutzens zu verformen, und beständig genug, um bei Abgastemperatur dicht zu bleiben. Genau deshalb ist es das Standard-Dichtmaterial für geschraubte Auspuffverbindungen.

Ein Verschleißteil

Ein Quetschring dichtet, indem er gequetscht wird. Hat er einmal die Form einer Verbindung angenommen, dichtet er die nächste nicht mehr ebenso gut — und das ist der übliche Grund, warum ein Stopfen, der letztes Jahr dicht war, dieses Jahr tickt. Bei einem Euro spricht nichts dafür.

Zwölf mal achtzehn

Zwölf Millimeter innen, achtzehn außen. Das Innenmaß muss zum Gewinde des Stopfens passen, das Außenmaß die Dichtfläche am Stutzen abdecken — ein Ring, der in einer der beiden Richtungen zu klein ist, dichtet auf nichts.

Bestellen

Einer je Stopfen. Wenn Sie TAPPO017 bestellen, bestellen Sie diesen mit — der Stopfen kommt ohne.
