Autoteile

Rubber seals play a critical role in the automotive industry, providing reliable sealing, vibration isolation, noise reduction, and protection against dust, moisture, oil, and other contaminants. Our comprehensive range of automotive rubber sealing solutions includes EPDM rubber seals, NBR O-rings, HNBR seals, FKM seals, silicone rubber gaskets, and custom-molded rubber components. Designed for demanding automotive applications, these sealing products are widely used in engines, transmissions, fuel systems, cooling systems, braking systems, air conditioning systems, and EV battery systems. With excellent resistance to heat, oil, chemicals, weathering, and mechanical stress, our automotive rubber seals help improve component reliability, extend service life, and ensure consistent performance. We also provide custom rubber seals and precision-engineered sealing solutions tailored to specific automotive designs, operating conditions, and OEM requirements.

Oil & Gas Industry

Our Oil and Gas Rubber Seals are designed for demanding applications in drilling equipment, pipelines, valves, pumps, and oilfield machinery. We provide durable rubber O-rings, oilfield rubber gaskets, and custom sealing solutions made from materials such as NBR, HNBR, FKM, and EPDM, offering reliable sealing performance under high pressure, extreme temperatures, and harsh chemical environments.

Pneumatic System

Our Pneumatic Rubber Seals are designed for reliable sealing in pneumatic systems, air cylinders, valves, compressors, and other compressed air equipment. We offer high-quality pneumatic O-rings, rubber gaskets, piston seals, rod seals, and custom pneumatic seals made from materials such as NBR, EPDM, and silicone. These rubber seals for pneumatic applications provide excellent air tightness, wear resistance, and dimensional stability, helping prevent air leakage and ensure efficient equipment operation.

Food

Rubber sealing components play an essential role in food processing, beverage production, and food manufacturing equipment. They provide reliable sealing performance, prevent leakage, and help maintain hygienic production environments. We offer a wide range of food-grade rubber sealing solutions, including EPDM O-Rings, Silicone O-Rings, FKM O-Rings, NBR Rubber Seals, HNBR Seals, and PTFE Seals, as well as custom rubber gaskets, sealing rings, and molded rubber components. With excellent resistance to temperature variations, oils, cleaning agents, and repeated washing (depending on material selection), our rubber seals are suitable for pumps, valves, pipelines, mixers, processing machinery, and other food-contact equipment. Custom sizes, materials, and specifications are available to meet different food industry sealing requirements.

Medical

Our medical rubber seals support healthcare applications beyond equipment alone—including diagnostic and laboratory systems, pharmaceutical processing, surgical instruments, dental devices, fluid handling and patient care products. Available in medical-grade silicone, EPDM and FKM, as medical O-rings, gaskets and custom medical seal parts, with custom sizes and OEM supply for medical and healthcare manufacturers.
