Gylon® Gasket Benefits:

GYLON®, a product of Garlock Sealing Technologies, is a reinforced PTFE gasket material that exhibits significantly reduced creep relaxation, along with outstanding chemical resistance.  The benefits of a Gylon® Gasket include:

  • Highly Resistant to Chemicals - capable of withstanding a broad range of chemicals during extended service periods.
  • Tighter Seal - provides superior performance compared to conventional PTFE; ensures reduced emissions and product loss
  • Significant Cost Savings - reduces operation costs by minimizing maintenance required; loss of fluids; minimal energy consumption; reduction in waste; lower inventory costs
  • Large Sheet Sizes Available - some of the largest sheet sizes available in the industry; this translates to better material utilization (more gaskets and seals per sheet), with less waste material
  • Easy installation, easy to cut - GYLON® Style 3540 is perfect for warped, scratched, pitted or wavy flanges.
