High Purity Backing Rings
High Purity Backing Rings are precision-engineered components designed to provide strong, reliable, and contamination-free support for high purity pipe flanges. These rings ensure uniform pressure distribution during flange tightening, preventing stress, deformation, and leakage in high-purity piping systems.
Manufactured from ultra-clean materials such as PVDF High Purity, PP-H High Purity, or PFA, these backing rings are used in industries where absolute cleanliness and chemical resistance are critical—including semiconductor manufacturing, pharmaceutical processing, biotechnology, and ultrapure water systems.
Their smooth surface finish, corrosion-free construction, and compatibility with high-purity flanges make them essential components for secure, sanitary, and long-lasting high-purity pipeline installations.
