Pure Silicon Rubber Cap

We supply silicon rubber Cap / Seal which provides a cost-effective method for the dust-tight transfer or containment of powders. By cutting a hole in the center of the cap, a dust-tight seal can be made with the penetrating spigot. This enables the contained charging of mills, tablet presses, vessels, drums / IBCs and almost any other item of process equipment where charging / discharging can produce dust. After the charging process is complete, the cap (with hole) can be replaced with a cap (without hole), to seal off the inlet.
