MULTI-SWELL™ Style 3760 / Style 3760-U (NSF-61 Certified) / 3760 Nuclear 10CFR 50 Appendix B Certified

 

Aramid fibers with a proprietary rubber binder

The MULTI-SWELL™ 3760 is the ultimate problem solver for those lightweight flange and covers where nuisance oil and water leaks plague most industrial facilities. Unlike traditional vegetable fiber and cork gaskets that allow water and oil to “wick” through the body of the gasket, the MULTI-SWELL absorbs the media at the inside edge, swells, and creates a tighter, long term seal.

  • Creates compressive load in lightweight flanges in oil and water service
  • More universal than gaskets that swell in oil only — reduces inventory
  • Performs well in flanges that might crush an elastomer gasket, providing use in a wide array of applications
  • More compressible than standard fiber gaskets and seals with low load
  • Easy to cut and handle — extremely flexible, minimizes waste
  • Replaces vegetable fiber gaskets in many applications — won't weep, improving plant safety
  • Seals flanges in "less than perfect" conditions minimizing maintenance
  • Specify 3760-U for applications requiring NSF 61 approved gaskets (Drinking Water)

High Temperature Cut Gaskets and Sheets

THERMa-PUR® is yet another innovative  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  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
