Tri-Clamp® FKM Perforated Plate Gaskets are manufactured with a 22 Gauge 316L Stainless Steel Perforated Plate that has been flow trapped into the gasket body. These perforated hole gaskets are available standard with 0.033", 0.045", 0.062" (1/16"), 0.094" (3/32"), 0.125" (1/8"), 0.187" (3/16") and 0.250" (1/4") perforations in varying center types, please see the reference chart below for exact specifications. The center type is the center to center distance between each perforation and correlates to the holes per square inch and open area % of each gasket.

With a stringent ASME-BPE design, these filtration gaskets can be utilized for particulate removal in a number or processes and industries. Whether being used as a pre-filter for expensive membrane filters, or straining particulate in fill and finish products, these sanitary gaskets can save you from equipment wear and product contamination.

FKM Tri-Clamp® Gaskets are specified by many process equipment manufacturers and are generally suitable for these applications, however service life must be considered and a preventative maintenance program must be in place to mitigate degradation. While acceptable, we do not recommend FKM Gaskets for continuous use in SIP (steam in place) procedures. With that said, FKM Sanitary Gaskets have excellent compatibility with strong acids and maintain a broad range of operating temperatures from -30°F to 400°F.

Storing FKM Gaskets:

  • Shelf Life: 10 Years from cure date
  • Store in original packaging in clean and dry warehouse
  • Do not expose to direct sunlight
  • Keep more than 6' away from electric motors
