Compression fittings work by using a compression nut and a ferrule to create a watertight seal between two pipes or tubing. The ferrule is placed inside the fitting and the nut is tightened, compressing the ferrule against the pipe. This compression creates a secure connection that prevents leaks. Compression fittings are commonly used in plumbing and gas lines due to their ease of installation and reliability. **

These fittings are called pipe fittings. They are used to connect and control the flow of liquid or gas in a piping system. Pipe fittings come in various shapes and sizes to accommodate different types of pipes and applications. They are essential components in plumbing, heating, and industrial systems. **

Hard tubes and fittings are components used in custom water cooling systems for computers. Hard tubes are rigid, typically made of materials like acrylic or PETG, and are used to connect various components of the cooling system such as the CPU block, GPU block, and radiators. Fittings are the connectors that are used to join the hard tubes together and to the other components of the system. Together, hard tubes and fittings allow for precise and customized routing of the cooling system, providing efficient heat dissipation for high-performance computers. **

For fittings, it is best to use a paint that is specifically designed for metal surfaces. Look for a paint that is labeled as suitable for use on metal, such as a metal primer and enamel paint. These types of paints are formulated to adhere well to metal surfaces and provide durable, long-lasting protection against rust and corrosion. Additionally, consider using a spray paint for easy application and a smooth finish on fittings. **
