Silicone Dust Caps
The Hanningfield Uni-Cap is a flexible silicone rubber seal which provides a cost-effective method for the dust-tight transfer or containment of powders.
By cutting a hole in the centre 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.
Available in 2.5″, 8″, 8″ (Tri-Clover profile), 10″, 12″ and 16″, the Uni-Cap is designed to be compatible with our range of stainless steel mounting rings. This allows the cap to be easily fitted or retro-fitted to any process.
As standard, the caps are manufactured from translucent silicone (FDA CFR 177.2600), although we can accommodate specific requirements for material (e.g. EPDM) or colour (e.g. blue) in dedicated batches to satisfy your application. We are also able to introduce new tooling for unlisted sizes upon request.
Dust Tight Seal between Outlet and Inlet
Here the spigot of the outlet penetrates the undersized hole in the silicone cap, providing a dust tight seal.
