There are several different uses for hydraulic fittings. For one, there are Flareless and O-ring types. In addition, there are Bite and Compression fittings. So, when choosing hydraulic fittings, ensure you know how they are used.
Flareless fittings
Flareless hydraulic fittings are a common component of hydraulic systems. They can be used in a wide range of applications. Whether you need to repair a system or a new connection, flareless fittings are a great solution. The advantages of this type of fitting are that they are reliable, easy to install, and have a tight seal. Flareless fittings are ideal for medium to heavy wall tubing. They also offer better vibration resistance. These fittings are commonly used in aerospace, military, and hydraulic equipment. Their durability is another reason why they are so popular. The body of these fittings is made of steel or stainless steel. Flareless fittings are available in many sizes and configurations. You can find them in brass, carbon steel, or stainless steel.
Hose flanges
Hydraulic hose flanges are designed to make connecting two hydraulic hoses easy and safe. They come in various sizes and can be easily installed on most types of equipment. These fittings are typically made of steel, aluminum, or forged steel. Some flanges are also available in stainless steel. Hose flanges are used in many industrial and construction applications, including fluid power transmission. Flanges are commonly used to connect hoses to other components within a hydraulic system. It is essential to choose the right fit to ensure safe connections. Choosing the right size can prevent leaks and lead to connection failures. To determine which fittings are best for your application, consider the type of hose you need to connect and the required pressure. A flange is an ideal choice if you use a larger-diameter hose. On the other hand, if you need to connect a smaller hose, an adapter is the better option.
Bite-type compression fittings
Bite-type compression fittings are designed with hydraulic tubing that does not need to be flared. This design provides a robust and leak-free connection. It can handle high pressures and vacuums. Bite-type compression fittings are characterized by a short ferrule that makes a bite into the tube. The leading edge of the ferrule is then driven into the tube surface. With each reassembly, the ferrule bites more profoundly into the tubing wall. A nut is used to tighten the ferrule. If the nut is overtightened, it can deform the compression fitting, causing it to leak. An O-ring face seal is often used to reduce this risk. Bite-type compression fittings are manufactured to industry standards. These are ideal for leak-free performance under severe conditions. They are also available in a wide range of temperatures and pressure.
O-ring type fittings
Different types of O-ring type fittings for hydraulics are suitable for various applications. These fittings provide a leak-tight seal and can help to prevent the loss of hydraulic fluid. In addition, these fittings are suited for dynamic and static applications. The SAE Straight Thread O-ring is an excellent choice for medium-pressure hydraulic applications. It is a versatile hydraulic fitting that offers a tight seal when the threads are forced into the female port. Another standard hydraulic fitting is the ORFS (O-Ring Face Seal) fitting. This type of fitting is typically used in dynamic and high-pressure systems and offers a leak-tight connection. ORFS connections are commonly manufactured in stainless steel or nickel-plated carbon. Depending on the application, fluorocarbon O-rings may be needed to meet specifications.
Hose sizing
Sizing hydraulic hoses can be a complicated process. Using industry standards and information to select the best hose for your application is essential. This includes the correct inner diameter (ID), outer diameter (OD), and length. If you fail to perform these steps correctly, you may end up with a hose that is too small or too large for your system. An improperly sized hose can cause leaks, inefficiency, or damage to your hydraulic fittings. A hose that is too large can also increase system pressure. Hydraulic hoses are usually made of steel or aluminum. They are commonly reinforced with additional layers of reinforcing wire.
