Delivering Fluid Sealing Solutions Since 1972


Fluid Seals for the Nuclear industry

M Barnwell Services provide a host of sealing products to the Nuclear Industry, including Gaskets, Inflatable Seals, Rubber Mouldings, and O-Rings. Our Nuclear Seals are available in all relevant materials. This includes FFKM, Nitrile, Silicon, Viton, EPDM and Fluorocarbon.

At M Barnwell Services we understand the specific challenges routinely facing the Nuclear Industry. We source high quality and robust seals to handle the extreme temperature and pressure demands required for the Nuclear Industry. As a result, there are many strict standards specific to the Nuclear Industry. This includes safety, reliability, resilience, which are routinely reviewed and refined. Thus, we ensure all our products adhere to these standards ensuring peak efficiency and performance.

High-Temperature Seals

  • MBMS1108 is a high purity FFKM that is designed to increase yields and reduce process contamination in Semiconductor applications. With excellent plasma resistance and outstanding long-term mechanical performance, it can also perform at 310°C.
  • MBMS0214 is another FFKM that operates at a high temperature of 260°C but also has the advantages of being rapid gas decompression (RGD) resistant and able to work under intense pressure environments (ultra-deep water HP/HT applications of 18,000 psi and 177°C (350°F) and above). This makes this material ideal for the Oil and Gas industry.

Other high-temperature seals are available. Contact the team for more information or visit the FFKM O Ring Page.

Low-Temperature Seals 

  • MBMS0493REV2 is designed to provide industry-leading resistance to a wide range of chemicals (including acids and amines) whilst operating at extremely low temperatures -46°C to +250°C (-51°F to +482°F). For these reasons the material is less prone to swelling, leading to an extended in-service performance in valves, pumps and mechanical seals.

We have many types of low-temperature seals available. Contact the team for more information or visit the FFKM O Ring/ fluoroelastomer (FKM / Viton™) page.
