O-rings are available in various elastomeric materials.  Versa offers a host of different O-ring and seal material options to create the most suitable match of the elastomer to the specific application.  The media, ambient conditions, lubrication and cycle rate affect the integrity and longevity of the O-ring.  In ideal conditions, O-rings can and will last 10 years or more.  Versa advises its customers to consult their local authorized Versa distributor to ensure proper O-ring selection and to develop a proactive maintenance schedule for your application.
