Materials and Processes
NBR
Oil-resistant O-rings and seals for hydraulic and general industrial applications.
FKM (Viton®)
Excellent resistance to chemicals and high temperatures.
FFKM (e.g. Kalrez®)
For extreme operating conditions with the highest temperature and chemical resistance requirements.
HNBR
Elastomer with improved temperature and ageing resistance for dynamic applications.
EPDM
Ideal for weather-exposed areas and contact with water, steam, or cleaning agents.
VMQ (Silicone)
Silicone elastomer for temperature-stressed seals, including in the food sector.
Thermoplastics (e.g. TPU)
Abrasion-resistant materials for hydraulic seals such as piston and rod seals.
Metallic materials
Metal components and sealing elements, e.g. DIN standard parts such as DIN 7603.
3D printing (additive)
Additively manufactured components for customer-specific special seals.
CNC turning
Turned custom seals made to drawing from elastomers, thermoplastics, and metallic materials.
