Seal rings are vital in preventing fluid or gas leakage across a wide range of equipment. The material of the seal ring largely determines its effectiveness and durability under specific conditions such as temperature, pressure, and chemical exposure. Below are the most common seal ring materials and their typical applications: · Nitrile Rubber (NBR): Ideal for mineral oils, lubricants, and mildly aggressive fluids. It performs well between –40°C and +120°C and is widely used in automotive, hydraulic, and general industrial applications due to its affordability and reliability. · Fluorocarbon Rubber (FKM): Known for outstanding resistance to high temperatures (up to +250°C) and aggressive chemicals. Commonly used in chemical plants, engines, and fuel systems where sealing performance is critical under extreme conditions. · Silicone Rubber (VMQ): Offers excellent flexibility and low-temperature resistance (down to –60°C). It is favored in food processing, medical devices, and electronic equipment that require high hygiene and environmental safety. · Ethylene Propylene Diene Monomer (EPDM): Resists steam, water, brake fluids, and ozone well. Frequently found in water treatment systems, solar heating units, and outdoor applications. · Polytetrafluoroethylene (PTFE): Chemically inert and resistant to almost all aggressive substances. With high temperature tolerance and low friction, it is suitable for chemical processing, pharmaceutical production, and cleanroom environments. · Hydrogenated Nitrile Rubber (HNBR): An upgraded version of NBR that provides enhanced heat resistance and mechanical strength. It performs well in high- pressure and dynamic sealing situations. Selection Advice: Choosing the right seal ring material requires consideration of multiple factors—operating temperature, fluid compatibility, pressure range, dynamic vs. static use, and expected lifespan. For standard conditions, NBR is often sufficient. In high-temperature or corrosive environments, FKM or PTFE is recommended. For food-grade or medical applications, VMQ or EPDM is more appropriate. Selecting the optimal material not only improves sealing performance but also reduces downtime and maintenance costs, ultimately enhancing overall equipment efficiency.

Agricultural machinery operates in high-intensity and complex environments, which places high demands on the sealing performance and durability of oil seals. Common oil seal materials include nitrile rubber (NBR), fluororubber (FKM) and acrylic rubber (ACM), which have good oil resistance, high temperature resistance and aging resistance, respectively, and are suitable for different working environments. In terms of models, the commonly used oil seal types for agricultural machinery are TC type (double lip with spring), SC type (single lip with spring) and cassette oil seals, which can effectively prevent lubricating oil leakage and external pollutants from invading. For example, the X24198, X24197, 24187, and 24188 oil seals provided by DEDE are widely used in the transmission systems of tractors, harvesters and other equipment.
