Silicone O-rings are available in AS568, metric and JIS sizes with material, hardness and compliance options selected according to the sealing application. Standard and custom dimensions can be matched to drawings, samples or specified groove requirements.
Silicone O-ring selection should begin with the material grade, hardness, size standard and application conditions. These requirements should be reviewed together so the selected compound and dimensions match the sealing position.
Standard silicone and selected Dow Corning silicone material options are available. Confirm the specific compound according to the sealing conditions and documentation required.
Choose AS568, metric or JIS dimensions according to the groove design, equipment standard or existing part specification.
Current capability covers ID 0.60 × CS 0.20 mm up to ID 1000.00 × CS 20.00 mm, subject to the selected material and specification.
Hardness options are available within the 20–90 Shore A capability, subject to the selected silicone compound and project requirements.
FDA, NSF, RoHS and REACH options may be available for selected compounds. Required documentation should be confirmed before material selection.
Confirm the operating medium, temperature conditions, sealing mode and installation requirements before selecting the silicone grade.
Compare material, hardness, compliance and dimensional requirements before confirming a silicone O-ring specification.

Drawing or Sample
Review the sealing position, operating medium and required material documentation together with the silicone grade and dimensions before specification.
For selected medical equipment assemblies, confirm the required silicone grade, hardness, dimensions and applicable material documentation.
For appliance sealing positions, select the silicone grade and dimensions according to the operating conditions, groove and assembly requirements.
For selected water-contact positions, confirm material compatibility and any required compliance documentation before specifying the silicone compound.
For static seals, review groove and compression requirements. For moving positions, also review speed, friction, lubrication and wear conditions before silicone is specified.
Provide the size standard or drawing together with hardness, operating conditions and documentation requirements so the material and dimensions can be reviewed as one sealing specification.
Provide the AS568 dash number, metric ID × CS dimensions or JIS designation together with the required material and hardness.
Provide a drawing, sample or specified inside diameter and cross-section together with the required dimensional tolerances.
Specify the required hardness, operating medium, temperature conditions and any material or compliance documentation needed for the project.
State whether the seal is static or dynamic and provide relevant groove, movement, pressure or installation conditions for review.
