Eppendorf SAMPLE DISP. FITTING O-RING P0626-0390

This item is an Eppendorf replacement O‑ring intended for the sample-dispensing fitting (sample port) used on Eppendorf instruments and assemblies. Its purpose is to provide a leak‑tight seal at the sample/dispense interface to prevent leaks and maintain reliable liquid handling when withdrawing or dispensing samples. Eppendorf documents that O‑rings are offered as replacement parts in different materials and sizes for sample ports and dispensing accessories.

Key Features:

• Intended application: replacement sealing ring for sample‑dispensing fittings and sample ports (manufacturer spare part).
• Material options (per Eppendorf listings): VMQ (silicone) and NBR; EPDM also listed for certain vessel/sample ports.
• Offered as OEM spare part / accessory within Eppendorf part families (P0626-series appears in distributor listings for sample-dispensing components).

Advantages:

• Restores a manufacturer‑specified, leak‑tight seal at the sample dispensing connection to reduce sample loss and contamination risk.
• Available in laboratory-compatible elastomer materials (silicone/NBR/EPDM), enabling chemical and temperature resilience appropriate for many dispensing applications.
• OEM replacement part ensures correct fit and compatibility with the matching Eppendorf fitting or port, simplifying maintenance and preserving instrument performance.
