01
Product Details
Standard IIRs are sulfur-cured. We can develop custom Butyl o-rings to meet customer applications or specifications.
Butyl is a synthetic rubber, a copolymer of isobutylene and isoprene. Butyl exhibits an extremely low gas permeability rating, making Butyl orings ideal seals in the military industry sealing gas mask and protective clothing. Butyl orings are also found in many other industries due to its diverse chemical resistance properties. Butyl o-rings are also referred to as isobutylene-isoprene orings or IIR o-rings. We can offer a complete selection of both the standard AS568 o-ring and metric o-ring sizes. We can also develop custom Butyl o-rings to meet customer applications or specifications.

Standard Isobutene Isoprene IIR Orings
Generally know as butyl rubber.
Butyl compounds have similar chemical resistance to ethylene-propylene. They display excellent resistance to air, water, dilute acids and alkalis; plus resistance to aliphatic phosphate-ester hydraulic fluids, salt solutions, alcohols, glycols and silicone oils.
Resistance to hydrocarbons is poor: butyl must not be used with mineral oils.
Fluid sealing duties：
Very low gas permeability makes butyl popular for vacuum and high pressure gas applications.
Standard grades：Supplied in grades of 60-70 IRHD.
