Today we’ll continue our look at spring-energized seals by exploring some of the preliminary considerations to made when working with these seals.
A spring energized PTFE seal is selected to fit an exact set of service conditions found in your application.
Gallagher Fluid Seals recommends conducting a review of the entire sealing environment. You should use the Engineering Action Request (EAR) form before selecting a seal design.
Evaluating the following check list will be beneficial to selecting a preliminary design.
