CUSTOM ITEM: Perbunan O-Ring, 5 x 1.2 mm. ARE-Applied Research brand. Bulk Price.
Additional Info:
The 46200‑OR Perbunan O‑Ring (NBR) is a precision sealing component designed for use in HPLC column hardware, guard column assemblies, and related fluid path connections. With a 5 mm ID × 1.2 mm cross-section, this O‑ring provides reliable sealing performance in low‑volume, high‑precision chromatography systems.
Manufactured from Perbunan (nitrile rubber, NBR), this O‑ring offers excellent chemical resistance, elasticity, and durability across a wide range of standard HPLC mobile phases. It is commonly used in bioinert PEEK systems and associated fittings, where maintaining leak‑free connections and consistent system pressure is essential.
✅ Key Benefits
Reliable Leak‑Free Sealing Maintains system integrity under routine HPLC operating conditions
Compatible with PEEK Column Hardware Systems Designed to work with bioinert column and guard column components
Excellent Chemical Resistance (NBR Material) Suitable for aqueous and many organic solvent systems
Precision Fit (5 × 1.2 mm) Ensures consistent compression and sealing performance
Durable & Reusable Withstands repeated installation and operation cycles
Performance & Material Characteristics
Perbunan (NBR) is widely used in chromatography sealing applications due to its balance of:
