Silicone Grease for Rubber O-Rings (Sealing & Assembly)
General guide for lubricating and assembling rubber O-rings and seals with silicone grease.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Seal Material | EPDM/NBR/Viton/silicone rubber; compatibility depends on chemistry. |
| Application | Assembly lubrication; static seals; light sliding contact. |
| Environment | Water exposure common; some greases are water resistant. |
| Temperature | Choose grease rated for expected range. |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Elastomer Compatibility | Confirm with seal manufacturer or grease datasheet. |
| Water Resistance | Helpful for plumbing/outdoor applications. |
| Non-Melting/Stable | Avoid wash-out and run-off over time. |
