Dual Vespel Ring Inlet Seals

Washerless, Leak-Tight Seals for Agilent GCs

More Details
Our patented Dual Vespel Ring Inlet Seal greatly improves injection port performanceit 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.
