Retaining Rings

Retaining rings are precision-formed metal components designed to secure the ends of expansion joints within a piping system. These rings provide axial retention and positional stability, preventing joint movement caused by pressure or vibration. Commonly used with rubber and fabric expansion joints, retaining rings help maintain a leak-free seal between the joint and mating flanges. They’re ideal for low- to medium-pressure applications across HVAC, water treatment, and industrial process systems.
