Products Description
Our EPDM PU Silicone Flat Rubber O-Ring Seals have been developed with care to provide strong sealing solutions for a variety of applications. These flat O-ring seals are excellent at resisting extreme temperatures, chemicals, and mechanical wear by combining the superior properties of EPDM( Ethylene Propylene Diene Monomer), PU( Polyurethane), and Silicone. They are ideal for a variety of industrial, automotive, and commercial applications because of their flat profile and even sealing surface.

Products Process
Material Selection: We only use high-quality materials like EPDM, PU, and Silicone, which are known for their long-lasting properties and resistance to chemicals and temperature extremes.
Compounding: To improve performance characteristics like elasticity, temperature tolerance, and chemical resistance, each material is individually compounded with a particular additive.
Molding: To maintain consistency in terms of quality and dimensional accuracy, the compounded materials are expertly molded into flat O-ring shapes using modern molding techniques.
Curing: To achieve the desired hardness and sealing properties, which increase their performance and longevity, the molded O-rings go through a controlled curing process.
Inspection: To ensure that each batch complies with industry standards, rigorous testing and quality control procedures, including dimensional verification and performance assessments.
Products Application
Automotive: Used in applications where temperature and chemical resistance are important for sealing engines, transmissions, and cooling systems.
Industrial: Suitable for machinery and tools that rely on unreliable sealing in environments with varying temperatures.
Aerospace: Provides dependable sealing for challenging, high-performance aerospace components.
Commercial: Suitable for use in plumbing, HVAC, and other commercial applications that call for long-lasting sealing solutions.
