Stoppers and Nozzles

VAPEX standard and plunger rod stoppers are ideal for autopouring units in iron foundries and are designed for long campaign and multi open / close sequences.

VAPEX ceramic / carbon bonded alumina graphite nozzles are available in standard taper and reverse taper designs and are ideally suited for autopour applications.

VAPEX cross bore nozzles produce a smooth, concentrated pouring stream and offer significant benefits over conventional designs.
