What is rubber sleeve?
A Rubber Sleeve is a basic type of coupling. This consists of a pipe whose bore is finished to the required tolerance based on the shaft size. Rubber Sleeves and buffers can be manufactured in a range of shapes, sizes and material to suit the application. Rubber Sleeves can be used for variety of applications such as covering joints, insulation in different mechanical parts and electrical applications, covering hoppers, etc.
rubber sleeve Material Types and Their Applications
The performance of a rubber sleeve depends heavily on the material selected. Different elastomers offer distinct resistance properties and operating ranges .
| Material | Temperature Range | Key Properties | Best For |
|---|---|---|---|
| Natural Rubber (NR) | ~ -50°C to 80°C | High flexibility, excellent resilience, tear resistance | General-purpose applications requiring high elasticity |
| Silicone | -45°C to 250°C | Extreme temperature resistance, flexible, food-grade options available | High-temperature environments, medical devices, electrical insulation |
| EPDM | -40°C to 120°C | UV, ozone, weather, and steam resistance; good for water and mild chemicals | Outdoor applications, automotive weather seals, hot water systems |
| Nitrile (NBR) | -35°C to 100°C | Oil, fuel, and chemical resistance | Automotive fuel systems, industrial machinery with oil exposure |
| Neoprene (CR) | -35°C to 100°C | Weather, oil, and chemical resistance; flame retardant | Industrial and automotive settings with moderate oil/weather exposure |
| Viton (FKM) | -20°C to 200°C | Superior chemical and high-temperature resistance | Aggressive chemical environments, aerospace, and high-performance applications |
