Hydraulic hose fittings are essential components in hydraulic systems that connect hoses, pipes, other components. The size and pressure ratings of hydraulic hose fittings are crucial in ensuring the safe and efficient operation of hydraulic systems. In this article, we will discuss the different sizes and pressure ratings of hydraulic hose fittings.
1.Hose Size
Hydraulic hose fittings come in different sizes that are designated by a dash number. The dash number represents the nominal size of the hose in sixteenths of an inch. For example, a dash 8 fitting is designed for a 1/2-inch hose, while a dash 16 fitting is designed for a 1-inch hose.
2.Thread Size
The thread size of hydraulic hose fittings is also important in ensuring proper connections. The most common thread sizes for hydraulic hose fittings are SAE straight thread and NPT thread. SAE straight thread fittings have a straight thread and a 45°flare seat. NPT thread fittings have a tapered thread and require the use of a sealant to prevent leaks.
3.Pressure Ratings
Hydraulic hose fittings have pressure ratings that are determined by the maximum working pressure of the hose. The pressure rating of a hydraulic hose fitting is typically higher than the maximum working pressure of the hose to provide a safety factor，it is typically measured in pounds per square inch (PSI) or megapascals (MPa).
4.Types of Fittings
There are several types of hydraulic hose fittings, including crimped fittings, reusable fittings, and push-on fittings. Crimped fittings are the most common type of hydraulic hose fitting and require a crimping tool to attach the fitting to the hose. Reusable fittings can be used multiple times and do not require a crimping tool. Push-on fittings are designed for low-pressure applications and can be easily pushed onto the hose without the use of tools.
In conclusion, the size and pressure ratings of hydraulic hose fittings are crucial in ensuring the safe and efficient operation of hydraulic systems. It is important to choose the correct size and pressure rating for your application to avoid damage for the hose and fittings, leaks, and system failure. It is also essential to follow proper installation and maintenance procedures to ensure the long-term performance of hydraulic hose fittings.
