Compression fittings are mechanical components used to join two pipes or tubes together, creating a tight, leak-proof seal. They are commonly used in plumbing, gas, and hydraulic systems. Compression fittings work by using a compression nut and a ferrule (or olive) to clamp down onto the pipe, providing a secure and reliable connection.

Different Types of Compression Fittings:
Based on Material:
- Brass Compression Fittings:Commonly used in plumbing and gas systems due to their strength, durability, and corrosion resistance.
- Stainless Steel Compression Fittings:Suitable for high-pressure, high-temperature, or corrosive environments.
- Plastic Compression Fittings:Used in low-pressure, non-corrosive applications, and ideal for connecting PVC, CPVC, and PEX pipes.
- Copper Compression Fittings:Used in copper piping systems for both plumbing and gas connections.
Based on Pipe Connection Type:
- Straight Compression Fittings:Connect two straight pieces of pipe or tubing in a line.
- Elbow Compression Fittings:Used to connect two pipes at an angle, typically 90 degrees, for directional changes.
- Tee Compression Fittings:Used to create a branch connection between three pipes, often in plumbing systems.
- Union Compression Fittings:Allows two pipes to be connected and disconnected easily, commonly used in maintenance.
Based on Seal Design:
- Single Ferrule Compression Fittings:Uses a single ferrule or olive to create a seal between the fitting and the pipe.
- Double Ferrule Compression Fittings:Utilizes two ferrules (one at each end of the fitting) to create a more secure and leak-proof connection.
- Swivel Compression Fittings:Allows rotation of the pipe after installation, providing flexibility in the system's design.
Based on Pressure Rating:
- Low-Pressure Compression Fittings:Suitable for non-pressurized or low-pressure applications.
- High-Pressure Compression Fittings:Designed to withstand higher pressure environments, often used in hydraulic or industrial systems.
Based on Specialty Applications:
- Medical Compression Fittings:Designed for use in medical gas and oxygen delivery systems.
- Food-Grade Compression Fittings:Made with materials that meet food safety standards, used in food and beverage processing.
- Pneumatic Compression Fittings:Specifically designed for air or gas systems, ensuring airtight seals.
Advantages of Compression Fittings:
- Reliability: Offers a reliable and secure connection that prevents leaks and maintains system pressure.
- Ease of Use: Requires minimal tools and is easy to install and remove, saving time and effort.
- Cost-Effective: Ideal for both DIY and professional use due to low installation and material costs.
- Reusability: Can be disassembled and reused, which is beneficial in maintenance-heavy systems.
- Corrosion Resistance: Ensures long-term durability, even in harsh environments or systems exposed to water or chemicals.
- Flexibility: Available in a wide range of sizes and materials to suit various systems and applications.
Compression fittings are a versatile and reliable solution for connecting piping systems in various industries, offering secure, leak-free connections with minimal maintenance.
