You will need special hydraulic hose fittings if you want to connect pipes, tubes, and hydraulic hoses to cylinders, valves, and pumps. Remember, any wrong fitting can increase safety issues and decrease the productivity of the entire hydraulic system. Undoubtedly, it is overwhelming to choose the right sealing and threading options, materials, and shapes.
For your assistance, here is a comprehensive guide to pick the right hydraulic hose supplies in Australian. These tips are enough to save your time.
Understand Assembly for Hose Fitting
In the first step, you have to decide the type of hose fitting during assembly. Crimping is a famous method to assemble hydraulic hoses. Make sure to ask about size, pressure, media/materials, application, and temperature. After defining specifications, the technician will start working. The process may vary according to the model of the crimper. To fit stems, you will need lubricants. Moreover, a power unit will help you to apply sufficient pressure to fit hoses securely.
Materials for Hose Fittings
Hoses and fittings are available in different materials and types. Remember, the material of hydraulic hose fitting often defines its characteristics. Some common fittings are brass, stainless steel, steel, and plastic. If you need something resistant to corrosion, you can choose plastic fittings. These fittings are weak; therefore, experts avoid them in hydraulic applications. Metal fittings are popular because of their high-pressure ratings.
For heat resistance and durability, steel fittings are suitable. These are made from a combination of iron and other metals. Carbon steel fittings contain carbon and iron; therefore, these can resist temperatures between -65 °F and 500°F. To manage temperature between -425 °F and 1200°F, you can choose stainless steel fittings. They are suitable for corrosive environments. Moreover, they rated over 10,000 psi. A few stainless steel fittings may be rated at almost 20,000 psi. Though, these are expensive as compared to other alternatives. As compared to stainless steel, brass fittings are less durable. You can use them for leak-free operations because brass fittings meet JIS, DOT, DIN, ISO, and SAE standards. Temperature for brass may range between -65°F and 400°F. They can accommodate 3000 psi pressure.
Hydraulic Hose Types
Hydraulic hose fittings are divided into two categories, such as field attachable and permanent crimp fittings. Permanent fittings are common and need a crimping machine to attach a fitting to a hose. Moreover, a field attachable is suitable because you will not need a crimper.
If you are using NPT pipe fittings, you have to be careful. It seems easy to fix leaks with this fitting type by tightening connections. You can use O-rings with elastomeric seals to avoid unexpected leaks. In this way, you can increase the chance of cracks in the fitting.
Modern equipment offers high operating pressure. If you want to address maximum operating pressure, you will need O-ring seals. These seals have resistance to cracks. Moreover, O-ring seals prove helpful to avoid the risk of leakage and over-torqueing. Remember, stainless steel hose fittings are famous for high pressure ratings.
