O-Rings O-Ring Types

Standard O-Ring Information

Standard O-ring Information O-rings are among the sealing classics at par excellence, this product represents highest form of diversity. It’s areas of application are as diverse as its variety, ranging from tap fittings to air- conditioning systems, from the car engine to the dental drill, each type requiring to meet the custom – specifications. Our mastery prevents the appearance of any parting lines thus rendering a seamless complete ‘O’ cross section to achieve precise sealing solutions.

O-Ring Types:

  • Round O-Ring
  • Lathe Cuts
  • Quad Rings
  • Back-up Rings
  • Encapsulated O-Rings
