LIP MATERIALS
 
R-Nitrile Buna-N 70 durometer compound is the standard material for seals and is recommended for the majority of common applications. Nitrile lip seals work well within a range of -40°F to 250°F temperatures and are compatible with water and most common mineral oils and greases.
 
P-Polyacrylate compounds are recommended for higher temperature applications ranging from -22°F to 300°F. They also work well with mineral oils, EP additives and greases. However, they offer poor sealing in dry running conditions and cost more than Nitrile.
  
 
S-Silicone compounds offer the widest range of normal operating temperatures ranging from -58°F to 356°F. However, they do not perform well in dry running conditions and should not be used with EP compounds and oxidized oils.
 
  
 
V-Viton®* compounds are premium lip materials offering the widest temperature range and chemical resistance. Viton® will handle temperatures from -40° to over 400°F (-40° to over 204°C). Viton® will resist most special lubricants and chemicals that can destroy Nitrile, polyacrylates and silicones. Viton® is extremely resistant to abrasion and provides superior wear and performance. Viton® works in dry running applications, but only for intermittent periods.
