Eppendorf O-ring Assy(S407447x5) 5720850570

The Eppendorf O-ring assembly is a manufacturer spare/sealing part used to replace worn seals in Eppendorf instruments and consumables. Eppendorf and authorized distributors list O-rings and sealing rings as replacement parts for items such as rotor lids, rotor bowls, pipettes and bench-scale/bioprocess vessels; their purpose is to restore an airtight or liquid-tight seal and maintain instrument performance. These assemblies are used during routine maintenance or repair to prevent leaks, preserve aerosol-tightness in centrifuges and ensure reliable operation of liquid‑handling devices.

Key Features:

• Product type: O‑ring assembly / spare sealing part for Eppendorf equipment (manufacturer spare part)
• Materials available (manufacturer): VMQ silicone (vinyl methyl silicone) and NBR rubber; multiple elastomer types offered for different applications
• Packaging/configuration: sold as replacement sets or assemblies (examples on distributor listings include multi‑piece sets such as 3‑piece assemblies and larger packs for pipette tip cones)
• Typical applications (manufacturer/distributor): rotor lids and rotor bowls, pipette sealing rings, bench‑scale and bioprocess vessel seals

Advantages:

• Restores airtight/liquid‑tight seals to prevent leaks and maintain aerosol containment in centrifuges and sealed vessels
• Available in different elastomers (silicone, NBR) so material can be matched to chemical and temperature requirements
• Sold as ready replacement assemblies or sets to simplify maintenance and reduce equipment downtime
• Manufacturer‑supported spare part — intended for direct replacement in Eppendorf equipment to preserve original performance
