Kalsi Seal Material Options
Standard HNBR Seal Materials*
| Material Dash No. | Material Name | Material Hardness, Shore A Durometer |
|---|---|---|
| -10 | HNBR (HSN) | 80 ± 5 |
| -11 | HNBR (HSN) | 85 to 92 |
*For elastomer selection considerations, see the Kalsi Seals Handbook.
Special Purpose / Special Order Seal Materials†
| Material Dash No. | Material Name | Material Hardness, Shore A Durometer |
|---|---|---|
| -2 | FKM | 70 ± 5 |
| -4 | FKM | 80 ± 5 |
| -6 | FKM | 90 ± 5 |
| -7 | FEPM (TFEP) | 70 ± 5 |
| -8 | FEPM (TFEP) | 80 ± 5 |
| -12 | EPDM | 80 ± 5 |
| -13 | EPDM | 90 ± 5 |
| -14 | HNBR (HSN) | 70 ± 5 |
| -15 | HNBR (HSN) | 90 ± 5 |
| -16 | HNBR (HSN) | 75 ± 5 |
| -30 | FKM | 80 ± 5 |
| -31 | FKM | 85 to 92 |
† The molding shrink rates of the FKM and TFEP materials differ from the shrink rate of the standard HNBR seal materials. Shaft and groove dimensions may require adjustment accordingly.

FEPM/FKM Material Combinations for Composite High Temperature Seals
| Material Dash No. | FEPM (TFEP) Inner Lip Hardness, Shore A | FKM Outer Lip Hardness, Shore A |
|---|---|---|
| -200 | 80 ± 5 | 80 ± 5 |
| -201 | 90 ± 5 | 90 ± 5 |
| -202 | 95 ± 5 | 80 ± 5 |
The molding shrink rate of certain composite high temperature material combinations differs from the shrink rate of the standard HNBR seal materials. Shaft and groove dimensions may require adjustment if the seals are made from tooling that is based on the shrink rate of typical HNBR seal materials, particularly with larger seal diameters. Due to shrink rate and lubrication considerations, it is recommended that dedicated tooling should be used for High Temperature Seals. Call for additional information.
