Dual Vespel® Ring Inlet Seals for Agilent GCs, Restek
Seals Mechanical Seals
Restek's patented dual Vespel® ring inlet seal greatly improves injection port performance—it stays sealed, even after repeated temperature cycles, without retightening the reducing nut.

  • Eliminate the need for a washer
  • Very little torque needed to make a leak-tight seal
  • Stainless steel seal for analyses of unreactive compounds

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.
