Product Details
RS PRO Nitrile Rubber Metric O-Rings
RS PRO metric O-Rings made from Nitrile, the most widely used elastomer in sealing applications. These O-Rings have an excellent resistance to petroleum products and work well in either low or high temperatures. Nitrile is highly resistant to abrasion and is an ideal choice in most industries.
Features and Benefits:
• Nitrile rubber material
• Hardness 70 shore A
• Continuous operating temperature -40°C to 110°C, short term to 135°C
• Resistant to mineral hydraulic oils and greases
• Tolerance BS4518
• Hardness 70 shore A
• Continuous operating temperature -40°C to 110°C, short term to 135°C
• Resistant to mineral hydraulic oils and greases
• Tolerance BS4518
Typical Applications:
Nitrile (NBR) is suitable for use within applications running at a maximum continuous temperature of 120°C (or up to 150°C intermittently). Use below -30°C requires special consideration. Seals and O-rings are used in various fields and industries including:

FAQs
Types of Seals and O-rings
Seals and O-rings come in various materials suited to different purposes. Some have a high temperature tolerance for use in both hot and cold applications, while others are made to be chemically resistant for use in lab or test equipment. Available in a wide range of sizes both in single size packs or in seal and O-ring kits for general maintenance. Sizes vary between seal and ring types both in diameter and thickness, these variations help provide an exact and precise seal to protect the joint. Both Metric and Imperial sizes are available to replace new and old seals and rings whether maintaining modern parts or older machines, engines and other mechanical parts.
