Internal Pressure Non-vented

OI-OGI-OSI-OVI

O/OG Type
  • Medium to high load
  • Medium to high leak tightness
  • Medium spring back
  • Available in shaped seal
OVI/OVE Type
  • Medium to high load
  • Medium to high leak tightness
  • Medium spring back
  • Available in shaped seal
OS Type
  • High load

  • Available in shaped seal

Please see tabs below to understand the information in this example.

Example: OI-007735-3.18M-3/0-1-S50

Seal Type
  • 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
Seal Diameter

007735 = 77,35 mm for groove OD 77,88 mm The seal diameter is always the outside diameter without plating. DSO = DG – DC – (plating thickness X 2) See figure below DSO = 77,88 – 0,43 – 2 X 0,05 = 77,35 mm

Cross Section

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.

Material

The first digit designates the O-Ring material, the second the spring material, in case an OSI-type is selected.

Treatment

1: Work hardened

Seal Plating

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.

Example: OE-006609-2.39M-3/0-1-N50

Seal Type
  • OE: External pressure, no venting
  • OVE: External pressure, O-Ring vented, system pressure energised
  • OSE: External pressure, O-Ring spring energised as of section 3,96
  • OGE: Low external system pressure, high temperature O-Ring gas filled
Seal Diameter

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

Cross Section

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.

Material

The first digit designates the O-Ring material, the second the spring material, in case an OSE-type is selected.
