Products Description
Sanitary gaskets are essential sealing components used in hygienic piping systems across the food, dairy, beverage, biotechnology, pharmaceutical, cosmetic, and other sanitary industries. They are designed for clamp-type connections and ensure leak-proof, hygienic sealing performance.
Available materials include NBR, FKM, EPDM, Silicone, and PTFE, all of which comply with FDA requirements, with several compounds also meeting USP Class VI standards for high-purity applications.
These gaskets ensure that the inner diameter of the gasket matches the inner diameter of the pipeline, providing a smooth, flush seal that eliminates contamination risk and reduces bacteria buildup.
Sanitary gaskets from Xiamen Best Seal Imp. & Exp. Co., Ltd meet CGMP, and comply with USDA and 3-A sanitary standards.
