Please see tabs below to understand the information in this example.
Example: OI-007735-3.18M-3/0-1-S50
- OI: Internal pressure, no venting
- OVI: Internal pressure, O-Ring vented, system pressure energised
- OSI: Internal pressure, O-Ring spring energised, as of section 3,96
- OGI: Low internal system pressure, high temperature O-Ring gas filled
The first digit designates the O-Ring material, the second the spring material, in case an OSI-type is selected.
1: Work hardened
Plating code “S” = Silver plating Plating thickness “50” = 30 to 50 µ
Product Features
Non-vented rings (OI & OE) are designed for lower pressure ranges. The perfectly closed O Ring design avoids ingress of the media into the seal. Moderate load, moderate pressure capability.

- OE: External pressure, no venting
- OVE: External pressure, O-Ring vented, system pressure energised

- OGE: Low external system pressure, high temperature O-Ring gas filled
006609 = 66,09 mm for groove OD = 65,66 mm The seal diameter is always the inside diameter without plating. DSI = DG + DC + (plating thickness X 2) See figure below DSI = 65,66 + 0,33 + 2 X 0,05 = 66,09 mm
Select the proper cross section or axial section (AS) in the table, then select the material code “M or H” based on the desired wall thickness.
The first digit designates the O-Ring material, the second the spring material, in case an OSE-type is selected.
