Dual Vespel Ring Inlet Seals, 0.8 mm, Stainless Steel, for Agilent GCs, 50-pk.

Our patented dual Vespel ring inlet seal greatly improves injection port performance—it stays sealed, even after repeated temperature cycles, without retightening the reducing nut! This seal features two soft Vespel rings, one embedded in its top surface and the other embedded in its bottom surface. These rings eliminate the need for a washer and ensure very little torque is needed to make a leak-tight seal. The rings will not harm the critical seal in the injector body, or any other surface, and are outside the sample flow path.

To reduce breakdown and adsorption of active compounds, use a gold-plated or Siltek-treated seal. Use a stainless-steel seal for analyses of unreactive compounds.

Features & Benefits

• Does not require a separate washer.
• Requires less torque to seal.
• Does not require retightening of reducing nut after several oven cycles.
• Extends column lifetime by preventing oxygen from reaching the column.
• Same price as the regular inlet seals with washers.
• Available in stainless steel, gold-plated, or Siltek-treated. Gold plating or Siltek treatment provide enhanced inertness versus stainless steel.
