The Max Spare style PUB seal is a general purpose seal & has a good overall performance. It is a seal suited for split piston but can also be used with a single piston if made in NBR.
The PUB seal is available in 2 materials: i.e. NBR and polyurethane. Due to its typical piston sealing design having a shorter external lip it allows pressure to act into the groove ensuring a maximum lip contact with the bore in pressurised conditions. Due to excellent wear resistance properties of polyurethane the life expected is 3 times that of NBR.
