O-ring grease is a specialized preparation protecting rubber seals against wear, cracking, and freezing. At Melkib, you will find both classic pastes and silicone o-ring grease, as well as dedicated formulas for air conditioning that protect O-ring seals from drying out and losing elasticity.

What is O-ring grease and why is it necessary?

• O-ring grease is a mixture of base oil (synthetic or silicone) with antioxidant additives creating a flexible coating on the seal surface.
• Prevents friction of rubber against metal or plastic and protects against harmful atmospheric factors.
• Maintains O-ring sealing properties, extending their life and reducing leakage risk.
• Choice: silicone formulas are universal and resistant to temperatures from –50 °C to +200 °C.

Key Properties

• Flexibility and adhesion: coating remains plastic, does not run or crumble.
• Temperature resistance: works in a wide thermal range.
• Oxidation protection: additives prevent rubber degradation under ozone and UV influence.
• Freezing protection: excellent for refrigeration and air conditioning installations.
• Material compatibility: does not attack typical construction plastics and metals.
