Perbunan O-Ring, 5 x 1.2 mm. ARE-Applied Research brand. 10/PK.
Additional Info:
The 46200‑OR‑010 Perbunan O‑Rings (NBR) are precision sealing components designed for use in HPLC column hardware, guard column assemblies, and fluid path connections. Supplied in a 10/pack configuration, these O‑rings are ideal for routine maintenance, high‑throughput laboratory workflows, and preventive service programs.
With a 5 mm ID × 1.2 mm cross-section, these O‑rings provide consistent compression sealing, ensuring leak‑free performance and stable system pressure in chromatography systems.
Manufactured from Perbunan (nitrile rubber, NBR), these O‑rings offer a balanced combination of flexibility, chemical resistance, and durability, making them suitable for aqueous and common organic mobile phases used in HPLC.
