Caps include frit, PEEK washer, PTFE O-ring, threaded insert, and snap ring.
Caps are serialized for easy sample identification.
We guarantee the compatibility of Restek and Dionex ASE parts only between entirely assembled caps and bodies. For example, if a Restek cap is assembled using all Restek parts, then it is compatible with a Dionex body. However, if a Restek cap has a Dionex insert (or vice versa), we cannot guarantee compatibility.
