Maroon material best known as the current version of the first Rulon® introduced (Rulon® A).
Rulon® AR is somewhat more flexible than Rulon® LR, hence suitable for seals and bonded coating of slide surfaces. It has many decades of use in automotive shaft seals and fuel metering pump cups.
Rulon AR has a practically universal chemical inertness like that of Rulon LR and provides long life and reliability in continuous non-lubricated service. It is capable of operating at PV values up to approximately 10,000. Higher PV values are possible for intermittent use applications.
Use the Rulon Materials Selection Guide to compare various Rulon grades.
