Restek™ Dual Vespel™ Ring Inlet Seals 
Extend column lifetime by preventing oxygen from reaching the column with these inlet seals. Restek™ Dual Vespel™ Ring Inlet Seals eliminate the need for a washer and ensure very little torque is needed to make a leak-tight seal.
Supplier: Restek™ RK21248
Description
- Washerless, Leak-Tight 1.2mm Seals for Agilent GCs
- Two per pack
- Does not require retightening of reducing nut after several oven cycles
- Same price as the regular inlet seals with washers
- Siltek treatment provides enhanced inertness versus stainless steel
- 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
- The rings will not harm the critical seal in the injector body, or any other surface, and are outside the sample flow path
- Use a stainless steel seal for analyses of unreactive compounds
- To reduce breakdown and adsorption of active compounds, use a gold-plated or Siltek-treated seal
