All PTFE & Tuf-Steel® Gaskets w/ ?100 Mesh Screens include a 10 Mesh backing screen. Due to the flow characteristics of PTFE, this is necessary to ensure entrapment of the screen within the gasket.Note: The following options are available as special order for these gaskets: metal detectable elastomers, special screen materials, larger diameters, and finer meshes. Let us know your requirements and we will be happy to quote them for you.Rubber Fab's PTFE Tri-Clamp Screen Gaskets are interchangeable with standard Tri-Clamp 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.PTFE Screen Gaskets are the material of choice where low temperature flexibility and seal memory are not required. We don't recommend using PTFE Sanitary Gaskets where large temperature variations frequently occur because the affect on the PTFE's density makes joints more prone to leakage. With that said we recommend using high pressure bolted clamps to help negate the affects of any temperature fluctuations. PTFE gaskets provide excellent heat resistance, second only to Tuf-Steel, with an operating range from -100F to 500F. From a chemical standpoint PTFE has good stability, almost no extractables, a low absorption rate, and excellent resistance to process fluids. These Tri-Clamp Gaskets can remain in service for long periods of time in both water and steam applications.
