HyClamp Sanitary Gaskets

HyClamp Type A and Type BHyClamp™ hygienic gasket seals are designed to meet the needs of pipe couplings in food, beverage and pharmaceutical process lines.  Free from animal-derived ingredients (ADI-free), HyClamp™ elastomer materials meet various international sanitary standards and approvals including FDA, USP Class VI and 3A 18-03 Sanitary Standards.

PPE specializes in manufacturing sanitary gaskets in Perlast® perfluoroelastomers (FFKM) and Detectaseal® metal detectable elastomers for critical applications.

Engineered to deliver optimal chemical resistance to satisfy the requirements of aseptic conditions, CIP (clean-in-place) and SIP (sterilization-in-place) processes; HyClamp™ seals provide excellent long-term sealing performance, therefore extending planned maintenance intervals and minimizing downtime.

HyClamp™ seals are manufactured to several clamp size standards conforming to current GMP (Good Manufacturing Practice) and supplied with full manufacturing batch traceability and certificates of conformity on request.

HyClamp™ elastomer gaskets:

  • Compliant with FDA, USP Class VI, 3A 18-03 Sanitary Standards
  • Free from animal-derived ingredients (ADI-free)
  • Optimal chemical and temperature resistance
