O-Ring Cord Information


Product Description:

Our High-Performance O-Ring Cord provides a versatile solution for various applications that require custom-made O-Rings. This O-Ring Cord, made from high-quality elastomeric materials, is specifically designed to be spliced and vulcanized to create custom O-Rings that meet specific requirements.

Technical Specifications:

  1. Material: Nitrile (Buna-N), Viton (FKM), Silicone, EPDM, or Neoprene, depending upon application requirements. Material choice will offer resistance to oils, chemicals, heat, or UV light respectively.

  2. Diameter Range: 1mm - 25mm. Allows for the creation of custom O-Rings with specific inner and outer diameter measurements.

  3. Hardness: 70 Shore A +/-5, 50 Shore A +/-5, 75 Shore A +/-5, 90 Shore A +/-5. These hardness range provides the cord with a balance between mechanical strength and elasticity.

  4. Tensile Strength: Minimum 12 MPa. This specifies the maximum amount of tensile (pulling) stress that the cord can withstand before breaking.

  5. Elongation at Break: Minimum 200%. This parameter determines how much the cord can be stretched from its original size before it breaks.

  6. Operating Temperature Range: -30°C to +120°C for Nitrile (Buna-N), -20°C to +200°C for Silicone, -15°C to +300°C for Viton (FKM), -45°C to +130°C for EPDM, and -40°C to +120°C for Neoprene. The temperature range signifies the operational environment suitability of the cord material.

  7. Colour: Black, or other colours depending on material and customer requirements.

  8. Resistance: Offers resistance to oils, fuels, and certain chemicals. Resistance properties depend on the material chosen.

  9. Compliance: RoHS and REACH compliant. This compliance ensures that the cord does not contain or release any harmful substances.

Applications:

High-Performance O-Ring Cord is used to create custom size O-Rings for static or dynamic applications including hydraulic and pneumatic systems, water and fluid systems, food processing equipment, chemical processing plants, and various types of manufacturing machinery.

Please note that the actual performance and suitability of the O-Ring Cord would depend on the specific application, the environment, and conditions in which it is used.


Product Name: Extruded Rubber O-Ring Cord

Product Description: Extruded Rubber O-Ring Cord is an essential component in various applications that require custom-made seals. Manufactured from high-quality elastomeric materials, the O-Ring cord can be cut to length, spliced, and vulcanized to create custom O-Rings that meet specific requirements. The cross-sectional tolerances of our O-Ring Cord adhere to the standards set by the Association for Rubber Products Manufacturers (ARPM).

Cross-Sectional Tolerances:

According to ARPM standards, the cross-sectional tolerances for extruded rubber O-Ring Cord are categorized based on the cord's nominal diameter. This categorization ensures that the manufactured O-Ring cord meets the precise dimensions required for effective sealing in various applications.
