Introduce

Flat rubber washers are a flat-shaped rubber seal made of rubber. They are mainly used to provide a sealing effect. They are flat in shape. Compared with traditional O-rings, their cross-sections are flatter and usually rectangular. or oval. This design enables it to provide an effective sealing effect under a certain compression force.

Certification standard

  • ISO 9001 is a certification standard for quality management systems that applies to all types of organisations. Obtaining ISO 9001 certification implies that the organisation has a comprehensive quality management system and can provide products and services that satisfy quality requirements.
  • ISO/TS 16949, on the other hand, is a certification standard for quality management systems in the automotive industry, specifically designed for automotive parts suppliers. Obtaining ISO/TS 16949 certification demonstrates that the supplier fulfils the quality management requirements of the automotive industry.
  • Regarding rubber materials, ASTM D2000 represents a standard for rubber material specification established by the American Society for Testing and Materials (ASTM). This specification defines the different grades, properties and test methods intended to ensure the quality and performance of rubber materials.
  • Concerning standards set by NSF/ANSI: NSF/ANSI standards apply to seals in contact with drinking water, such as flat rubber washers. Securing NSF/ANSI certification signifies that the seal meets the safety and sanitary requirements for drinking water.
  • FDA certification is of paramount importance for flat rubber washers used in food and drug contact. Obtaining FDA certification confirms that the seal meets FDA regulations for materials in contact with food and drugs.

Application

  1. Pumps and valves: flat rubber washers can be used in pump and valve systems. They can provide a stable sealing effect, prevent leakage of media in the equipment, and are suitable for sealing requirements under different pressure and temperature conditions.
  2. Pipe connections: flat rubber washers can be used to seal pipe connections, including pipe flange connections and pipe fitting connections. They can avoid liquid or gas leakage in the pipeline system and provide reliable sealing effects.
  3. Engine and auto parts: It is also commonly used for sealing of engines and auto parts, such as cylinder head seals, intake manifold seals, oil pan seals, etc. They are able to withstand high temperature and high pressure environments and ensure the proper operation of engines and automotive systems.
  4. Mechanical equipment: It can also be used for the sealing needs of various mechanical equipment, such as pressure vessels, pumping stations, compressors, fans, etc. They can prevent media leakage and protect the safe operation of equipment.
  5. Electronic and electrical equipment: Flat rubber washers are also used in electronic and electrical equipment to provide electrical insulation and waterproof sealing functions. For example, they can be used for connection interfaces of electronic instruments, sealing of electrical control boxes, etc.

Advantage

  1. First, flat rubber washers have excellent sealing properties. Its shape is flat, so it can perfectly fit the parts that need to be sealed, forming a tight sealing area to prevent the leakage of liquids, gases, powders and other substances. The material used to make this sealing ring is highly elastic rubber, which can withstand different pressure and temperature changes and has relatively long-term sealing performance.
  2. Secondly, its installation is also relatively convenient. It does not require special tools and equipment for installation, and it can be easily installed in a smaller space. Save time and reduce labor costs.
  3. Third, flat rubber washers have high wear resistance. It can be used for a long time, and the sealing ring is not easy to break or damaged, which can effectively protect the mechanical equipment and extend its service life. Moreover, the sealing ring is made of rubber material, which has reliable quality and long service life.
  4. Fourth, it also has good anti-pollution properties. It can prevent dust, sediment, oil and other impurities from entering the interior of mechanical equipment, thereby protecting the operation of mechanical equipment. This contamination-resistant seal also significantly reduces maintenance costs and repair risks.
