Garlock MULTI-SWELL® 3760

Garlock MULTI-SWELL® 3760

Aramid Fibers with a Proprietary Rubber Binder - Controlled Swell Sheet Gasketing

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.

Features & Benefits

  • 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)
