Siicone Rubber O Ring High Quality Food Grade FKM HNBR O Ring Material

Rubber O Ring Application

Rubber O-rings find diverse applications across various industries due to their excellent sealing properties. Here are some common applications of rubber O-rings:
Automotive: O-rings are used in engines, transmissions, fuel systems, and cooling systems to seal connections, prevent leaks, and maintain proper fluid flow.
Hydraulic Systems: O-rings are critical components in hydraulic systems, providing sealing in cylinders, pumps, valves, and fittings. They withstand high pressures and ensure efficient and leak-free operation.
Pneumatics: O-rings are utilized in pneumatic systems to seal air or gas connections, preventing leakage and ensuring reliable operation of valves, cylinders, and fittings.
Plumbing: O-rings are commonly used in plumbing applications to create watertight seals in faucets, valves, toilets, and other plumbing fixtures.
Aerospace and Aviation: O-rings are employed in aircraft engines, hydraulic systems, fuel systems, and various components that require reliable sealing under extreme conditions.
Industrial Machinery: O-rings are used in machinery and equipment to seal moving parts, prevent leaks, and maintain efficient operation. They can be found in pumps, compressors, valves, and other mechanical systems.
Electronics: O-rings are used in electronic devices to provide sealing and protection against moisture, dust, and other contaminants. They are commonly found in connectors, switches, and sensors.
Medical and Pharmaceutical: O-rings are utilized in medical and pharmaceutical equipment, such as syringes, IV devices, and pumps, to ensure sterile and leak-free connections.
Food and Beverage: O-rings made from FDA-approved materials are used in food and beverage processing equipment to provide hygienic seals and prevent contamination.
Oil and Gas: O-rings are used in the oil and gas industry for sealing applications in pipelines, valves, pumps, and drilling equipment, ensuring safe and efficient operations.

Rubber O Ring Certificate

Approvals : SGS , NSF , KTW , WRAS , UL , FDA etc . Special requirement is available.

NSF : NSF is specialized in standard setting, product testing and certification services in the fields of public health, safety and environmental protection, and is an authoritative body in the field of public health and safety

KTW : The supplier is required to comply with DVGW (German Gas and Water Association) Regulation W 270 "Propagation of microorganisms on Non-metallic materials". This standard mainly protects drinking water from contamination with biological impurities. All drinking water systems and excipients exported to Europe must be KTW certified. Therefore, if Chinese drinking water systems and excipients are to be exported to European countries, they must pass KTW certification. KTW has been authorized by the World Health Organization (WHO) for the certification of safe drinking water.

WRAS : WRAS(Water Regulations Advisory Scheme) certification refers to the Water Regulation Advisory Scheme. WRAS is the certification of the safety of drinking Water in the UK.

UL : Founded in 1894, UL has become one of the world's leading testing and certification organizations with a complete set of management systems, standard development and product certification procedures.

SGS:SGS certification refers to the service that SGS performs compliance certification on targets according to standards, regulations, customer requirements and other conditions. To carry out relevant certification, we must pass inspection, testing, authentication, certification and other means (SGS certification itself is not a certification, but refers to the certification service of SGS)
