PVC Transparent Backing Rings
The PVC Transparent Backing Ring is a supportive flange component used in transparent PVC piping systems to provide structural reinforcement and secure bolted connections. Designed for use with transparent PVC stub-end flanges, these backing rings ensure strong, stable joints while allowing full visibility of the fluid pathway when paired with transparent components.
Made from high-quality clear PVC, they are lightweight, corrosion-resistant, and ideal for applications that demand monitoring of flow, leakage detection, or hygienic handling of sensitive fluids. Their precision-molded design ensures perfect alignment, easy installation, and long-lasting performance.
