Spider Performance
  • Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity and operates effectively in temperature range of -40° to 212° F (-40° to 100° C). Good resistance to oil. Standard elastomer. (Also applies to SXB Cushions.)


Features

Features 
  • Fail-safe – will still perform if elastomer fails
  • No metal to metal contact
  • Resistant to oil, dirt, sand, moisture and grease
  • More than 850,000 combinations of bore sizes
  • Most types available from stock in 24 hours
