The InsoLion® FS gasket is James Walker’s performance isolation gasket and utilises a patented triple seal design. This incorporates a coated metallic core housing a modified u-shaped TFM seal energised with a phynox® spring.
This configuration means that InsoLion FS combines exceptional fugitive emissions performance, chemical compatibility and electrical isolation with the capability of maintaining sealing performance after API 6FB 3rd Edition fire test.
To validate the performance of InsoLion FS, 3rd party witnessed testing successfully completed included fugitive emissions to Shell MESC SPE 85/300 2017 3.3.2, Hot Operational tightness (HOTT) Shell MESC SPE 85/300 2017 3.3.5 and electrical 1500V isolation Shell MESC SPE 85/300 2017 3.3.15 API 6FB 3rd Edition Fire Test.
InsoLion® FS heads up a comprehensive range of flange isolation products from James Walker, which includes the InsoLion G11 variant that also holds a Shell TAT approval and, like the FS model, offers fugitive emissions levels significantly lower than those required under Shell MESC SPE 85/300 3.3.2 Class A (HS).
