Plastic Rings With Spring Energized Seals and Rubber Backup Elements

We manufacture the spring-energized seals to maintain repeatable fit and dimensional control. For these spring energized seals, we track compression targets, tolerance bands, and durometer to maintain the intended stack-up. You can submit a engineering requirements packet when sealing stack-up control is critical. From a drawing, we confirm groove diameters before tooling. Production for these parts are performed at our ISO 9001–certified Wuhu plant, which runs extrusion, injection molding, and rubber sealing lines. Pricing and lead time follow material family and the durometer range you specify. Production timing also closely reflects batch quantity and required inspection depth.
