Custom Rubber O-Rings

At I.B. Moore, we provide O-rings in a range of materials for multiple industries. Our custom rubber sealing rings are available in different sizes and compounds to meet a variety of application needs. Common materials include:

  • Nitrile (typically 70 or 90 durometer. Other durometers on request.)
  • Neoprene
  • Silicone
  • EPDM (glycol base)
  • Viton® 75


The right material and size help create an effective seal. Depending on the selected compound and application, our O-rings can provide a tight barrier at low pressure and offer resistance to heat and chemicals.
