Rubber Fab's Buna Tri-Clamp® Screen Gaskets are interchangeable with standard Tri-Clamp® Sanitary Gaskets for ease of use. These fluid filtration gaskets feature a 316L stainless steel screen, making them suitable for high purity systems. The screens are available in a variety of mesh sizes ranging from 4 Mesh up to 100 Mesh. Fluid filtration gaskets provide the most comprehensive range of stainless steel mesh and filter cloth to provide the ultimate particulate elimination for protecting fill and finish sterile products. All Rubber Fab Screen Gaskets feature Dutch Twill weave which provides for maximum strength and minimum pressure drop.
Buna Tri-Clamp® Gaskets are specified by many process equipment manufactures 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 Tri-Clamp® Gaskets for Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated hydrocarbons, or nitro hydrocarbons.
