<h1>Norsok Approved Compounds</h1>

Norsok approved compounds certified to industry standards

NORSOK standards are internationally recognised testing methodologies developed by the Norwegian Petroleum industry. The M-710 standard defines requirements for critical polymeric seals, seats, and back-up materials for permanent subsea use. The standard also applies to topside valves in critical gas systems.

Eastern Seals (UK) Ltd supply wide range of NORSOK approved materials. They are suitable for a variety of critical services and applications, enabling our customers to select the appropriate compounds to suit their specific needs. Our products have been qualified against the strict NORSOK M-710 rapid gas decompression (RGD) and the effects of sour gas (H2S) ageing on polymer materials.

Eastern Seals provide a range of formulations within the HNBR, Viton B, Viton GLT and FFKM materials that have passed the M-710 requirements. These are listed in the table below.
