What are Steel Ferrule Fittings?
Steel ferrule fittings are made to fit a ring that has a threaded end, such as an axle, gears, or a drive shaft. There are two types of ferrule fittings, namely double and single. Both are designed for use with a standard threaded nut or bolt. You can choose between these depending on what your application requires. However, there are some advantages to using a dual ferrule fitting as opposed to a single one.
Feature of Stainless Steel Ferrule Fittings
Steel Ferrule Fittings create a tight and leak-free seal between tubing and pipes. These fittings are available in various grades and shapes to suit the application. They are a popular choice for many industries. There are two main ferrule types, compression, and single ferrule.
Compression-style fittings are designed to hold the tube under pressure. This is important, as the softer tubing will likely collapse away from the ferrule.
The compression nut is inserted into the body and engages with the back end of the ferrule. Once the nut is inserted, it should be turned to secure the ferrule in place. Depending on the material, torque can vary greatly.
In high-pressure applications, the double ferrule design is preferred. Double ferrules offer better sealing technology than single ferrules.
Types of Ferrule Fittings
Single Ferrule Fittings
Single Steel Ferrule Fittings are the ideal choice for certain applications. They are known for their ease of assembly and for their ability to resist vibration. Compared with other fittings, they offer fewer seal failures.
These fittings are made from 316 stainless steel, which provides a tight leak-free connection. They also allow for easy replacements. However, they do not have as much pressure rating as double ferrule fittings. In addition, the softer tubing can lead to the collapse of the ferrule away from the tube.
Double Ferrule Fittings
Double Ferrule Fittings are a type of fitting that provides a tight, torque-free, leak-proof connection between two tubes. They are used in a variety of industries, including chemical and pharmaceutical manufacturing, hydraulic applications, and pneumatic systems. These fittings are available in a variety of materials and coatings, as well as a wide range of configurations.
These fittings are designed to work with a wide range of pressures. In general, they are rated to handle the maximum working pressure of the tubing. This is based on the material, thickness, and type of tube. For example, brass alloys are rated at 300/1000/30000 PSI, while stainless steel is rated at 6000 PSI.
Twin Ferrule Fittings
Double or twin Steel Ferrule Fittings are designed to provide leak-free connections. They offer close tolerance control in machining and surface smoothness. These types of fittings are used for various applications.
These ferrules are constructed out of a nut and a body. This design allows for easy installation and maintenance. The threads are silver-plated for seizing prevention. When purchasing these fittings, make sure that they are made from high-quality materials. For example, stainless steel is a popular choice for food service, chemical, and oil industries.
