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:

  • Chemical compatibility with water, methanol, acetonitrile, and buffered mobile phases

  • Good resistance to wear, compression set, and deformation

  • Reliable elasticity for consistent sealing under pressure

This O‑ring is optimized for analytical and semi‑analytical flow paths, where even minor leaks can compromise:

  • System pressure stability

  • Retention time reproducibility

  • Analytical accuracy


System Role & Integration

This component is typically used in:

  • Guard column holder assemblies

  • Column end fittings and sealing interfaces

  • PEEK hardware connections requiring compressive sealing

  • Low dead-volume fluid path junctions


⚠️ When to Replace O‑Rings

Replace the O‑ring when:

  • Visible deformation, cracking, or wear occurs

  • System exhibits leaks or pressure instability

  • Routine preventive maintenance is being performed

  • Ensuring consistent chromatography results is critical
