Metal O Rings

Metal O Ring Seals for the most extreme applications

M Barnwell Services are the UK’s leading independent manufacturer, stockist, and distributor of Metal O Rings. Metal O Rings are a high-performance sealing solution and are designed to enhance the performance of extreme applications.

Metal O Rings

Metal O Rings are used when rubber and alternative non-metallic seals do not provide adequate dependability for the installation, most of the time due to stresses, environment or temperatures. Furthermore, they can withstand a broad range of temperatures, hard vacuum, high stresses, corrosive chemicals and intense amount of radiation. Consequently, they are lifelong seals and are not liable to misperformance due to unconformity with the outgassing, environment or from collapse due to age (unlike elastomeric seals).

Metal O Rings are typically created from tubing, which usually contains high-temperature alloys (Inconel) or stainless steel. They are frequently used due to resilient features of these materials which make it possible for the seal to ‘spring back’.

These seals are ideas as static face type seal; however, they are not recommended to be used as a dynamic seal. Therefore, they work just like a gasket between two flanges, which have a very little or no movement between them. They are produced not only in circular shape but also rectangular and many more diverse shapes and configurations.

The advantages of a Metal O Ring Seals include:

  • High-temperature capability
  • Ability to withstand low temperatures
  • Present vacuum
  • Ability to withstand extreme applications (radioactive, corrosive)
  • Reusable in many cases
  • Present a long-term seal – no material disintegration
  • Long storage life
  • Self-energizing forces
  • Optimized spring  back, load and outer sealing layered hardness
  • Chemical compatibility
