JOINED GASKETS & O RINGS

Joined silicone gaskets and O-rings are sealing components created by bonding the ends of an extruded silicone profile. This allows straight lengths of silicone extrusion to be formed into circular rings, rectangular frames and more complex gasket shapes.

Silco Products can produce butt joints and mitred corner joints. Butt joints are commonly used to create circular rings, while mitred joints can be used for rectangular or shaped frame gaskets.

Using the same silicone material for both the extrusion and the joint helps create a more uniform component. It can provide consistent material properties across the finished gasket while producing a strong and dependable bond.

Yes. Silco Products’ joining system can be used for both simple and complex extruded profiles. The suitability of a particular profile will depend on its shape, dimensions and the required finished gasket design.

Yes. Silicone O-rings and joined rings can be manufactured to suit application-specific dimensions. Providing the required internal diameter, cross-section, material grade and quantity will help the team assess your requirements.

Yes. Extruded silicone profiles can be joined using mitred corners to create rectangular or other framed gasket configurations. These are suitable for applications where a continuous seal is required around doors, panels, glazing or equipment openings.

A joined O-ring is produced by cutting an extruded silicone cord or profile to length and bonding the ends together. A moulded O-ring is formed as a complete ring in a mould. The most appropriate option depends on the required size, profile, quantity and performance conditions.

Yes. Silco Products’ production capabilities include silicone washers as well as O-rings, joined rings and fabricated gaskets. These can be produced in different dimensions to suit insulation, spacing, sealing and protection requirements.

Provide a technical drawing or sample where possible, together with the finished dimensions, extrusion profile, silicone grade, hardness, colour and required quantity. Details of temperature, pressure, compression and environmental exposure are also helpful.

The correct component depends on the sealing surface, groove design, required compression, operating temperature and exposure to pressure, chemicals or weathering. Silco Products can review your specification and help identify an appropriate silicone material and joint configuration.
