Nitrile O-rings

Ensuring the Safety and Compliance of Materials for Potable Water Ensuring the safety and compliance of materials in contact with drinking (potable) water is a critical responsibility for engineers, manufacturers, and contractors in the UK. The Water Regulations Advisory Scheme (WRAS) provides a robust framework to certify materials for potable water use, verifying that products will not compromise water quality, public health...

Correct O-ring installation is essential for achieving a reliable, leak-free seal. Whether you are installing an O-ring in an internal (bore) groove or an external (shaft) groove, using the correct fitting techniques helps prevent twisting, pinching, cuts and premature seal failure. Improper installation is one of the most common causes of O-ring failure, particularly in dynamic or high-pressure applications. By following a...

Different elastomers behave differently in cold environments, and understanding how they retain their flexibility is essential for ensuring long-term sealing performance. One of the most widely recognised methods for evaluating the low-temperature performance of rubber compounds is the TR10 (Temperature Retraction – 10%) test. Standardised by ASTM D1329 and ISO 2921, TR10 provides engineers with a repeatable method for comparing how elastomers recover after...

What is Compression Set? Compression set occurs when an elastomer undergoes permanent deformation and fails to fully recover its original shape after being subjected to prolonged compression. In sealing applications, this loss of elasticity can significantly reduce sealing performance and increase the risk of leakage. A common example is an O-ring that remains flattened after extended service. As the material loses its...

O-rings play a critical role in the reliability of countless sealing applications. While selecting the right elastomer is essential, applying a specialist coating can further enhance performance, helping O-rings withstand demanding operating conditions while improving efficiency and reducing maintenance. Why Coat an O-Ring? An O-ring coating is a thin surface treatment that adds functional properties without significantly altering the dimensions...

This article will explain the main differences between Nitrile vs Viton®. Two of the most commonly approved elastomers, Nitrile (popularly referred to as NBR or Buna-N) and Viton® (Fluorocarbon rubber). Both materials are a great choice for general industrial use, they offer excellent compression set resistance and have a versatile set of properties list of applications and properties.
