Vilsum Nylon Metric Core Vents


Vilsum Nylon Metric Vents are injection molded for high precision. Available from 6mm to 20mm in diameter and a slot width of 0.4mm, these vents provide a "non-stick" surface combined with the toughness of nylon. Ideal for medium to high pressure molding, they are highly recommended for use in blow squeeze machines, v-process, and with cold box and CO2 sand systems.

Our core box air release vents are now sold in full bag quantities (100 vents/bag).

These vents have a minimum purchase of 5 bags and must be purchased in multiples of 5 bags.
