Customized EPDM NBR Silicone O Ring Sealing Element for Oil and Gas Seals As per Buyer's Drawing
  
  Type: O Ring
  Size: ID X CS, OD=ID + 2XCS
  
  
   An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross
  section (from which the "O" in its name is derived). The purpose of using O-ring seals is to 
  prevent leakage and loss of liquids or gases. They simplicity,convenience, and small installation
  space. As long as the groove design and material selection are correct, and the operating conditions
  are within the temperature range of the rubber material, the seal can have a long-term sealing 
  effect in the static or dynamic seal.
  The size of o-ring is determined by the inner diameter ID and the wire diameter CS. O-ring size
  calculation:
  outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
   
    O-Rings are used in sanitary pipeline systems for the Auto, Machinery, Food, Dairy, Beverage, 
  Pharmaceutical and Bio-Tech industries. Rubber Fab offers a full line of AS568 dash numbers,
