What is a Containment Cap?

Very simply, a Containment Cap is a Silicone disk or cap, which snaps onto a metal collar that has been made a part of a chute, vessel or process. It is typically used to transfer a powder from point "A" to point "B" with full containment of dust during the transfer. Typically, either the discharge point or the receiving point is portable.

The cap is normally made a part of the receiving point. An undersized hole is cut in the cap to mate with a metal spigot, which is part of the discharge point. When mated with the undersized hole, the silicone cap provides a tight, friction fit between the two points.

This results in full dust containment when product is permitted to flow from point "A" to point "B". If a scale system is included on either side, the cap also provides the necessary flex connection for accurate weighing.

If you are familiar with the general product you may know them as "Dust Caps", "Silicone Caps" or "MO Seals". We have chosen to call them Containment Caps and manufacture them here in the US so that the economy and next day availability can be passed on to the American market.
