In-house cutting, extrusion and vulcanising

Silicone gaskets

We manufacture silicone gaskets for static and dynamic sealing: die-cut or CNC-cut from sheet, O-rings, inflatable seals and vulcanised frames. The compound is chosen by application: temperature, contact medium and standards.

Does your gasket start from a drawing or a sample? Tell us geometry, medium and temperature: the usual path starts with made-to-measure flat silicone gaskets.

Formats and fitting

Gasket formats we manufacture

Each format solves a different seal: static or active, in a groove or as a frame. These are the common ones; any variant is studied on drawing.

Die-cut flat gasket · ProSilicones64
Die-cut flat gasket Cut from sheet by CNC or die: free geometry with no mould cost.
O-ring · ProSilicones64
O-ring Static sealing in a standard groove; diameters and hardnesses per application.
TIXAN'AIR® inflatable seal · ProSilicones64
TIXAN'AIR® inflatable seal Hollow profile that grows with compressed air and seals large or irregular gaps.
Frame-vulcanised gasket · ProSilicones64
Frame-vulcanised gasket Ends joined by vulcanising: a closed frame with no weak splice point.

Silicone gaskets in various geometries and hardnesses
Certified material

Materials and compounds for every standard

The same gasket behaves differently depending on the compound: solid silicone from 30 to 80 Shore A, sponge or cellular when closing force is low, from −60 °C to +230 °C continuous.

We compound to requirement: FDA 21 CFR 177.2600 and EC 1935/2004 food grades, ISO 10993 and USP Class VI medical grades, and EN 45545-2 railway grades up to HL3. Every batch ships with its certificate.

Other elastomers

Silicone or FKM/Viton™?

Silicone wins on temperature range, ageing and certified food and medical grades. FKM/Viton™ wins when the medium is mineral oil, fuel or aggressive chemicals: there silicone swells and the fluoroelastomer holds.

If your medium points to the second group, we also manufacture made-to-measure FKM and Viton™ flat gaskets with the same CNC and die-cutting processes.
