Agilent Ferrule, 0.4mm VG 0.25 col 10/PK 500-1004

This is an Agilent pack of VG (Vespel/graphite) capillary ferrules (500-1004), designed to make the 1/16" to 0.4 mm ID connection between a GC/GC‑MS instrument and a 0.25 mm ID capillary column. Manufacturer and authorized distributor descriptions state these non‑porous Vespel/graphite ferrules provide leak‑free seals for column inlet and detector connections and are suitable for GC and GC‑MS use.

Key Features:

• Ferrule inner diameter: 0.4 mm (1/16" × 0.4 mm ID)
• Compatible column ID: 0.25 mm (capillary columns)
• Material: Graphite/Vespel (VG) — typically 15% graphite / 85% Vespel
• Pack quantity: 10 ferrules per pack
• Maximum operating temperature: up to ~350 °C (for VG ferrules)

Advantages:

• Non‑porous Vespel/graphite construction minimizes outgassing and contamination, making it suitable for MS applications.
• Provides reliable, leak‑free seals between capillary columns and GC injector/detector to maintain chromatographic integrity.
• Resistant to deformation and can be reinstalled, allowing reuse and reducing replacement frequency.
• Sized for 0.25 mm capillary columns and standard 1/16" fittings for broad compatibility with common GC systems.
