Note
Always check the chemical compatibility of the O-ring material with your application. If
the O-ring material is not compatible with its chemical environment, the O-ring may
eventually malfunction.
No wetted O-rings are used in the HTHP, HP, and C versions. Final rating may be lower
depending on flange and material of construction selection.
