Which material families are available for O-rings?
O-rings and sealing rings for industrial applications.
O-ring material families
O-rings are available in EPDM, Neoprene, NBR, VMQ silicone, FKM, FVMQ and HNBR. Each material family serves different contact media and temperature requirements.
Choosing a compound
Start with the working medium, temperature and mechanical loading. NBR and HNBR are used for oil-contact sealing; EPDM is considered for water and weather-exposed interfaces. Silicone, FKM and FVMQ offer different combinations of temperature behavior and fluid resistance. Confirm compatibility for the selected compound.
Dimensions and installation
Provide the gland geometry, cross-section, diameter and required compression. Dimensions, hardness and finishing are selected for the assembly and checked using a representative sample.
