An O ring is a mechanical gasket or a circular sealing ring placed between two meeting surfaces to minimize frictional damage and consequent leakages if fluids are involved. In other words, it is a loop of elastomer which is designed to be seated in a groove and compressed when two or more parts are assembled, forming a seal at the interface. Helix Engineering is a top provider of high-quality seals and O-rings made of Nitrile rubber. O-ring joints are connections made by two identical parts, each with an O-ring groove in the face, sealed with an O-ring, and held together by clamps. The clamps are the same as those used for ball and socket joints. They do not need grease, and can provide a good vacuum tight seal.Nitrile, also known as NBR or Buna-N, is a copolymer of butadiene and acrylonitrile.. Nitrile O-rings are the most cost-effective and widely used worldwide.

Properties of Rubber Used In Nitrile O-Rings

Nitrile O-rings provide an excellent balance of working properties as mentioned below:
• Low compression set
• High tensile strength
• High abrasion resistance

Specifications Of Nitrile Rubber

Temperature Range
Nitrile O-Rings are suitable for a temperature range of -40°C to 120°C.

Nitrile O-Rings Application
Nitrile O-rings are widely used in a wide range of applications where it will be exposed to hydrocarbons, oils, petrol, water, hydraulic fluids, Petroleum greases, mineral oils, vegetable oils, aliphatic hydrocarbons, hydraulic fluids (HFA, HFB, HFC types).
This material has limited resistance to dilute acids, alkalis, and solvents.
Nitrile compounds are not resistant to ozone, sunlight, or weather. They should not be kept near electric motors or other ozone-producing equipment.
