An O-ring is a torus, or doughnut-shaped ring, generally molded from an elastomer, although O-rings are also made from PTFE and other thermoplastic materials, as well as metals, both hollow and solid. This handbook, however, deals entirely with elastomeric O-rings. O-rings are used primarily for sealing.

 rubber O-ring is a sealing component made from neoprene (CR - chloroprene rubber), known for its oil, chemical, and weather resistance. These O-rings are widely used in industrial, automotive, marine, and HVAC applications due to their durability and flexibility.

Key Features of Neoprene O-Rings:

✅ Oil & Chemical Resistance – Moderate resistance to petroleum-based oils, greases, and chemicals.
✅ Weather & Ozone Resistance – Performs well in outdoor applications exposed to UV rays and ozone.
✅ Water & Fluid Resistance – Suitable for fresh and saltwater applications, commonly used in marine environments.
✅ Temperature Range – Typically -40°C to 120°C (-40°F to 248°F).
✅ Moderate Compression Set Resistance – Maintains sealing properties under pressure.

Common Applications:

🔹 HVAC Systems – Seals refrigerants and prevents leaks in air conditioning systems.
🔹 Automotive & Machinery – Used in fuel systems, engines, and brake fluids.
🔹 Marine & Water Applications – Found in gaskets and seals for boats and underwater equipment.
🔹 Industrial Equipment – Used in pumps, valves, and hydraulic systems

A silicone rubber O-ring is a circular gasket made from silicone rubber, designed to create a seal between two or more parts. It is commonly used in industries such as automotive, aerospace, medical, and food processing due to its excellent temperature resistance, flexibility, and durability.

Key Features of Silicone Rubber O-Rings

✅ Temperature Resistance: Withstands extreme temperatures from -60°C to 230°C (can go up to 300°C for special grades).
✅ Chemical Resistance: Resistant to water, ozone, UV, and some chemicals, but may not be ideal for petroleum-based fluids.
✅ Flexibility & Elasticity: Maintains its shape and sealing properties over a long period.
✅ FDA & Medical Grade Available: Suitable for food and medical applications.

Common Applications

• Automotive & Aerospace: Sealing in engines, fuel systems, and high-temperature areas.
• Medical & Food Industry: Used in medical devices and food processing equipment due to its non-toxic properties.
• Electronics & Industrial Equipment: Protects against moisture and dust in sensitive equipment.
