Dual Vespel® Ring Inlet Seals

By Restek
Dual Vespel® Ring Inlet Seals

Features:

  • Vespel® ring embedded in bottom surface eliminates the need for a washer
  • Vespel® ring embedded in top surface requires very little torque to seal — reducing operator variability.
  • Lower leak rate compared to OEM metal inlet seals for less detector noise.
  • Oxygen prevented from permeating the carrier gas, increasing column lifetime.

The Dual Vespel® Ring Inlet Seal greatly improves Agilent split/splitless 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.

For analyses of unreactive compounds, use a stainless steel seal. To reduce breakdown and adsorption of active compounds, use a gold-plated or Siltek®-treated seal. The gold surface offers better inertness than untreated stainless steel; Siltek® treatment provides inertness similar to that of a fused silica capillary column.
