Cam and Groove Perforated Plate Gaskets - Buna

Buna Perforated Plate Cam and Groove 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 a 0.033" perforation and 0.055" straight line center, but other configurations are available, please contact us for details. This standard perforation contains 330 holes per square inch for a 29% open area. 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.

Buna Camlock 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. Buna Gaskets have excellent resistance to petroleum based fluids, making them the economical choice for seals in engines and equipment where petroleum based oils, lubricants, and fuels are present. Chemically, Buna is resistant to many hydrocarbons, fats, oils, greases, hydraulic fluids, and chemicals. Never use Buna Gaskets for Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated hydrocarbons, or nitro hydrocarbons.
