Internal Pressure

C Ring Internal

Characteristics
  • Medium to high load
  • Medium to high leak tightness
  • Medium spring back
  • Available in shaped seal

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

Example: CI-009931-3.96M-2/0-2-SN50

Seal Type

CI: Internal pressure, system pressure energised

Seal Diameter

009931 = 99,31 mm for groove OD = 99,82 mm The seal diameter is always the outside diameter without plating. The diameter is calculated as follows: DSO = DG – DC – (plating thickness X 2) See figure below DSO = 99,82 – 0,41 – 2 X 0,05 = 99,31 mm

Axial Section

Select the proper 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 C-Ring material, the second is always “0” in case of a C-Ring.

Plating

Plating code “SN” = Tin plating Plating thickness “50” = 30 to 50 µ

C Ring Internal Spring Energised

Characteristics
  • High load
  • High leak tightness
  • Low spring back
  • Available in shaped seal

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

Example: CSI-024563-4.78M-2/2-1-S50

Seal Type

CSI: Internal pressure, spring energised

Seal Diameter

024563 = 245,63 mm for groove OD = 246,19 mm The seal diameter is always the outside diameter without plating. DSO = DG – DC – (plating thickness X 2) See figure below DSO = 246,19 – 0,46 – 2 X 0,05 = 245,63 mm

Axial Section

Select the proper axial section (AS) in the table, then select the material code “M or H” based on the desired spring load.

Material

The first digit designates the C-Ring material, the second specifies the spring material.
