High quality plastic clamp ring assembly made from engineering plastics such as Nylon, POM or UHMWPE. Durable, corrosion-resistant and lightweight. Ideal for pumps, valves, automation equipment and industrial sealing applications. Custom sizes available.

This product is a high-strength engineering plastic retaining ring assembly, manufactured using wear-resistant and corrosion-resistant engineering plastic materials. It is designed for use in the sealing, securing, and clamping mechanisms of various industrial devices. The assembly consists of a main ring and a clamping ring; it is secured via bolts inserted through metal-lined mounting holes, enabling it to firmly clamp rubber seals, diaphragms, or piping components, thereby ensuring excellent sealing performance and structural stability during equipment operation.

Widely utilized in automation equipment, chemical machinery, food processing machinery, pump and valve systems, and various other industrial applications, this product features exceptional corrosion resistance, lightweight construction, high structural strength, and a long service life.

Constructed from high-quality engineering plastics (such as Nylon PA, POM, or UHMWPE), the product exhibits superior mechanical strength and wear resistance, ensuring stable and reliable long-term performance in complex industrial environments.

Compared to metal components, these plastic retaining rings offer exceptional resistance to chemical corrosion, making them ideal for use in equipment within chemical processing, food manufacturing, and humid environments.

Featuring a through-hole design with a metal bushing insert, the product allows for rapid fastening via bolts, ensuring a stable and reliable clamping and securing effect.

The use of engineering plastics—which are significantly lighter than metals—helps reduce the overall load on equipment, thereby enhancing operational efficiency.

Product dimensions, hole positioning, materials, and colors can all be customized according to client specifications to meet the specific installation requirements of various types of equipment.
