Extruded & mould joined

This approach proves particularly economical when a high degree of precision is unnecessary: i.e., for large diameter non-standard O-rings used in static duties.

The ring is made from a length of extruded elastomeric cord by vulcanising the ends together in a moulding tool.

This method must not be confused with rings joined together by contact adhesive. Generally, the use of such adhesives results in a less secure joint with operational temperature limitations below that of the elastomeric cord material.

Rings need a minimum diameter section of 3mm and minimum inside diameter of 200mm. Maximum ID is unlimited. Custom O-rings can be produced very swiftly by this technique, and our flexible production schedules enable us to meet the most urgent demands.
