Our Dual Vespel® Ring Inlet Seal* greatly
improves injection port performance—it stays
sealed, even after repeated temperature cycles,
without retightening the reducing nut! This new
version of our popular Vespel® Ring Inlet Seal
features two soft Vespel® rings, one embedded
in its top surface and the other embedded in its
bottom surface. The Vespel® 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, and are outside the sample flow path.
Tests show Dual Vespel® Ring Inlet Seals will
seal equally effectively at torques from 5 to 60
in. lb.
Why trust a metal-to-metal seal when you can
make leak-tight seals quickly, easily, and more
reliably—without a washer, with a Restek Dual
Vespel® Ring Inlet Seal. Use an untreated stain-
less steel seal for analyses of unreactive com-
pounds. To reduce breakdown and adsorption of
active compounds, use a Siltek™-treated or gold-
plated seal. Siltek™ treatment provides the high-
est level of inertness.
