Olives Ferrules

Olives Ferrules

“Olives” and “ferrules” are terms often used interchangeably in the context of compression fittings, but they refer to slightly different components of the fitting. Both play a crucial role in creating a secure and leak-resistant connection in compression fitting assemblies.

Ferrule (Compression Ring): A ferrule, also known as a compression ring, is a small cylindrical component made of metal, plastic, or other materials. It is a critical part of a compression fitting that forms a seal between the fitting and the pipe or tubing. When the compression nut of the fitting is tightened, it presses the ferrule against the pipe or tubing, causing the ferrule to deform and create a tight seal. The ferrule helps prevent leaks by compressing the pipe material and effectively sealing the joint.

Olive (Compression Sleeve): An olive, also known as a compression sleeve or compression nut, is another component of a compression fitting. It is usually a small, tapered cylinder with a central hole that matches the outer diameter of the pipe or tubing. The olive slides onto the pipe or tubing before the fitting is assembled. When the compression nut is tightened, it pushes against the olive, which in turn compresses the ferrule against the pipe or tubing to create a seal.

Usage: In various regions and industries, the term “ferrule” is often used to refer to the compression ring, while “olive” or “compression sleeve” is used to describe the tapered component that fits over the pipe or tubing. In practice, these components work together to achieve the desired seal in a compression fitting.

Function: When assembling a compression fitting, the olive (compression sleeve) is typically placed onto the pipe or tubing first. The ferrule (compression ring) is then positioned over the pipe end, directly underneath the olive. When the compression nut is threaded onto the fitting body and tightened, it pushes against the olive, which compresses the ferrule against the pipe or tubing. This compression creates a tight seal that prevents fluid leaks.

Materials: Both olives (compression sleeves) and ferrules (compression rings) connectors manufactured by Conex Metals are available in Brass and Stainless Steel. The material choice depends on factors such as the type of fluid being transported, compatibility with the piping material, and the system’s pressure and temperature conditions.

In summary, while the terms “olive” and “ferrule” are often used interchangeably, they refer to distinct components of a compression fitting. The olive (compression sleeve) fits over the pipe or tubing, and the ferrule (compression ring) is positioned beneath it. Together, they play a crucial role in creating a reliable and leak-resistant seal in compression fittings.
