Tri-Clamp® Orifice Plate Gaskets - FKM
Note: FKM Orifice Plates ship with a blank plate finished to 15 µ-in Ra as standard, but we are happy to accommodate special requests for hole boring (concentric or eccentric), electropolishing, metal detectable elastomers, and custom cut patterns. Click to submit a Request for Quote.
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
