The 4-inch Dixon Valve & Coupling 40MPS-U4 Tri-Clamp screen gasket uses Buna-N (NBR) elastomer and a 10-mesh stainless steel screen to seal while enabling filtration in sanitary piping. Constructed for Tri-Clamp sanitary fittings, it combines Buna-N with a 316 stainless steel screen, and the 10-mesh construction provides defined filtration while maintaining a tight seal. Common applications include dairy, beverage, and pharmaceutical processing lines, with the 4-inch size matching catalog entries such as 40MPS-U400 and the 10-mesh standard.
