HyClamp Sanitary Gaskets
HyClamp™ hygienic gasket seals (also known as Tri-clamp® and Tri-clover® 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.
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.
FFKM Sanitary Gaskets
FFKM sanitary gaskets are fully fluorinated, designed to overcome specific sealing challenges found in the food, dairy, pharmaceutical, biomedical and life-science industries.
Perlast®, the ultimate perfluoroelastomer (FFKM) is ideal for SIP and CIP cleaning regimes. Designed for sealing applications where chemical resistance and high temperature performance are critical, FFKM sanitary gaskets can withstand steam, amines and solvents.
The unique cross-linking system employed in all Perlast® grades ensures compatibility with virtually all chemicals. The molecular structure of Perlast® perfluoroelastomers is very similar to PTFE, providing excellent thermal stability and chemical resistance. This enables users to rationalize onto a single material grade across all applications.
Metal-detectable Sanitary Gaskets
Detectaseal® is a range of metal detectable elastomer compounds designed specifically to meet the stringent demands of the pharmaceutical and food processing industries. Detectaseal® sanitary gaskets have been tested and proven in use at leading pharmaceutical and food manufacturing plants. Fragments of Detectaseal® as small as 2mm can be identified by metal detection equipment.
HyClamp™ elastomer gaskets:
- Compliant with FDA, USP Class VI, 3A 18-03 Sanitary Standards
