Insolion® G10

The Insolion G10 gasket consists of a modified u‑shaped TFM seal energised with a phynox spring.

  • Oil & Gas

The TFM material was chosen for its advanced mechanical properties and improved resistance to permeation. This sealing element is bonded to a high strength G10 glass reinforced epoxy and 316L stainless steel composite core.

The complete flange isolation kit supplied with the gasket includes G10 bolt sleeves and isolation washers as standard and will offer extremely high levels of electrical isolation from cryogenic temperatures up to +150˚C.

  • Flange isolation for critical applications in the oil, gas and other processing applications
  • Media compatibility with natural gas, oils, other hydrocarbon media and many corrosive environments
  • Specified for plant wide use on the majority of flange specifications including ASME, API, EN, BS and DIN
  • Flange insulation and electrical isolation in conjunction with cathodic protection
  • Insulation between dissimilar metals/flanges to prevent galvanic corrosion
  • The position of the TFM spring energised seal allows the gasket to be used across all types of flange styles including ring joint and raised face flanges

  • Maximum temperature: +150°C (+302°F)
  • Minimum temperature: -150°C (-238°F)
  • Maximum pressure: 69 MPa/690 bar (10000 psi) (ASME Class 2500)

  • TAT approved to Shell MESC SPE 85/300 3.3.2 Class A (He)

  • Insolion G10 can be supplied in sizes from NB 1/2" to 40" diameter to match the majority of flange specifications and can be manufactured in IBC and full face styles
  • Custom dimensions and sizing options are available upon request
  • Insolion G10 is supplied as a kit suitable for the specific flange size and class rating required. This kit includes:
  1. Insolion G10 gasket
  2. G10 bolt sleeves
  3. G10 washers
  4. Metallic backup washers in 316 stainless steel
  5. Fitting guide
