How to Specify Hydraulic Hose Fittings
Hydraulic hoses carry fluid between components, but when they aren’t connected securely, there is a greater risk of high-pressure spillage. That’s why the fitting that connects the hose to components like valves and cylinders is so critical. Here are some tips to remember when specifying the fitting for a hose.
3 Tips to Fit Hydraulic Hoses
1. Ensure the Threads Match
Threads are the ridges on the fitting and the mouth of the hose that lock them together. Sometimes threads will appear to match and seal even when the connection is weak. To ensure they’re correct, check the sizes and types before assembling them. Then seal the hose tightly by crimping it, which involves compressing its metal collar.
2. Pay Attention to Chemical Compatibility
Both hoses and fittings come in a wide variety of materials, but not all materials can handle all types of substances. For example, rubber compounds that are not specially manufactured for chemicals will often swell when exposed to them. Temperature is another variable involved. Before using a hose or fitting, check the manufacturer’s specifications for the range of temperatures that it is equipped to handle.
3. Always Use Components From the Same Manufacturer
Although it’s common practice to use hoses from one manufacturer with fittings from another, this increases the danger that the connection won’t seal correctly and something will come loose while running the hydraulic system. To avoid these situations and prevent liability issues, hoses should always be matched with the fittings they were designed to be used with from the same manufacturer.
