About the P3 O-Ring Coller(thick and thin), which of them are anyone preference and share me their difference, please?
Best regards
With the thick oring coller only 1 oring is used with the thin oring coller 2 orings are used.
2 orings less leakage longer lasting shocks but more sticktion.
I use the thin coller with 2 orings.
You can also buy the blue low friction orings comes in a pack of 8.
