Color Marking Rings (Series HP) are essential accessories for STAUFF Quick Release Couplings, specifically designed for the Series HP range. These rings are used to visually distinguish between different lines or systems within carbon steel push-to-connect couplings equipped with poppet valves. Made from durable materials, they ensure long-lasting identification and organization in industrial applications. The color marking rings enhance safety and efficiency by allowing quick and easy identification of fluid types or system functions, thereby reducing the risk of errors during maintenance or operation.
