Welcome to SEMicro!
Each piston comes complete with the required gasket(s), prelubricated and installed!
The F-8/12 (F-20) Piston, the largest piston we stock at SEMicro, is like having 3 pistons in 1: an F-8, an F-12 and combined as an F-20. This piston is great if you will be testing many different coatings with different adhesion characteristics. It provides the most flexibility of any piston in our line.
Important: The psi strengths listed are based on 1/2" diameter pull stubs. If you are using any other sized stub, please contact us prior to purchasing a piston to make sure you will be testing in the range desired.
