O-ring cord is a versatile and flexible sealing solution used in a wide range of industries, including automotive, aerospace, and manufacturing. It is a cost-effective alternative to pre-molded O-rings, as it allows for custom-made seals to be produced quickly and easily. O-ring cord is available in a variety of materials, including NBR, EPDM, FKM, and VMQ (FDA), which have different properties and are suitable for different applications.
NBR (Nitrile Butadiene Rubber) O-ring cord is a popular choice for applications that require resistance to oil, fuel, and grease. It is also known for its excellent compression set and resistance to abrasion, making it a reliable choice for seals used in heavy machinery and automotive applications.
EPDM (Ethylene Propylene Diene Monomer) O-ring cord is ideal for outdoor applications, as it has excellent weather resistance and is less prone to cracking or hardening when exposed to sunlight or ozone. It is commonly used in seals for doors, windows, and other outdoor applications.
FKM (Fluorocarbon) O-ring cord is a high-performance material that is suitable for applications that require resistance to high temperatures and chemicals. It is commonly used in the aerospace and chemical industries, where exposure to harsh chemicals and extreme temperatures is common.
VMQ (MVQ - Silicone) cord is a food-grade material that is suitable for use in the food and beverage industry. It is resistant to high temperatures, chemicals, and bacteria, making it a reliable choice for sealing applications in food processing and packaging equipment. Our VMQ rubber cord is also FDA Aproved which means it can safely used in the food and drink industry.
O-ring cord is produced by extruding rubber material into a continuous cord, which is then cut to the desired length and joined to form a seal. The cord is then vulcanized to ensure that it maintains its shape and sealing properties even under extreme conditions. Vulcanization involves heating the cord to a specific temperature and pressure, along with a vulcanizing agent such as sulfur, which creates a cross-linking network that improves the material's strength, elasticity, and resistance to heat, chemicals, and wear.
