EMI can offer a complete range of precision O-rings conforming to international standards in both solid and cellular elastomeric materials. Ranges covered include BS1806, BS4518, AS568A, DIN 3770, SMS1586, JIS B2401 and ISO 3601, as well as non-standard O-ring sizes including miniature and micro.
Standard solid O-ring materials include Silicone, Fluorosilicone, EPDM, Neoprene, Viton®, Nitrile, Carboxylated Nitrile, Hydrogenated Nitrile, Polyurethane, PTFE, Teflon(FEP or PFA) encapsulated O-rings, Aflas®, Isolast®, Kalrez®, or Chemraz®.
Along with our Solid Elastomer O-Rings we can also offer a limited number of sizes for moulded Sponge O-rings in a range of materials including, Neoprene, Nitrile, EPDM and Silicone. Although at present we have a limited range of sizes we can lay down new tooling if there is sufficient requirement.
Custom Grades including MilSpec, Def STAN, NSN, AS & DTD available. Below is a sample of common grades. Contact us for your unique requirements.
