Rubber Seal Type | Advantages | Disadvantages |
---|---|---|
O-rings | Excellent sealing, easy installation | Limited pressure resistance |
V-rings | High-pressure resistance, robust construction | More complex installation |
U-cups | Versatile, dynamic sealing | Can be sensitive to high pressures |
Quad-rings | High sealing ability, durable | More costly than other types |
Lip seals | Effective for rotating/reciprocating motion | Can be vulnerable to wear |
Material | Temperature Range | Hardness Range | Resistance to Oils |
---|---|---|---|
Nitrile (NBR) | -40°C to 120°C | 50 to 90 Shore A | Excellent |
Fluorocarbon (FKM) | -20°C to 260°C | 60 to 90 Shore A | Excellent |
Silicone (SI) | -60°C to 200°C | 20 to 60 Shore A | Good |
Ethylene Propylene Diene Monomer (EPDM) | -50°C to 150°C | 40 to 80 Shore A | Good |
Polytetrafluoroethylene (PTFE) | -180°C to 260°C | 50 to 100 Shore A | Excellent |
