Custom Rubber Gaskets Manufacturing

Julong Rubber manufactures custom rubber gaskets for industrial sealing, cushioning, insulation, and assembly applications. We support OEM and ODM production based on drawings, samples, or application requirements, with material options including EPDM, NBR, silicone, FKM, natural rubber, SBR, CR, and other custom elastomer compounds.

Our rubber gaskets are used in HVAC systems, automotive components, pumps, valves, electrical enclosures, machinery, and general industrial equipment. Buyers can specify hardness, thickness, tolerance, color, surface finish, working temperature, oil resistance, weather resistance, and compliance requirements such as RoHS, REACH, or FDA-related material options.

Send us your drawing, sample photo, material requirement, quantity, and working conditions. Our team will help review gasket material selection, tooling, sampling, production method, inspection, and export packaging for your project.
