THERMa-PUR® Style 4122 High Temperature Cut Gaskets and Sheets

THERMa-PUR® is yet another innovative Garlock sealing solution that provides more than just temperature resistance. Style 4122 is designed for use in high temperature sealing applications. It is produced using an environmentally friendly solvent-free process and combines a unique formulation with Garlock’s traditional quality. THERMa-PUR® out performed vermiculite based gaskets in laboratory testing, showing significantly less leakage even in extreme thermal cycling condition.

  • Extreme Temperature – Able to withstand high temperature, whether continuous or in thermal cycling conditions
  • Chemical Resistance  –  Proprietary fomulation is resistant to a broad range of chemicals: Titanium Tetrachloride, molton salts and other heavy oxidizers
  • Oxidation Resistance – Contains proprietary materials that provide improved weight loss characteristics over other high temperature solutions
  • Hydrophobic (water resistant) – Resists water and provides electrical isolation thus reducing the possibility of corrosion between flanges made of dissimilar metals
  • Easy Release from Flanges – Does not stick to flanges making removal of gaskets easy and fast
  • Continuous Max:
    1832°F / 1000°C
  • Pressure:
    500 (34.5)  psig (bar)       
  • Chemical Compatibility – Please consult Applications Engineering
  • Gasket Factor ‘M’- 3.0
  • Gasket Factor ‘Y’- 10,000
