Within all industries, high-pressure fittings are essential for any fluid system as they play a crucial role in maintaining the safety of the system’s operation. Installing high-pressure fittings that follow through routine maintenance and don’t require constant repair or replacement enhances the success of your operation.
If and when the time comes to replace your high-pressure fittings, it’s critical to make sure you have access to the right parts you need. Two of the most common pressure fittings in the Fluid & Control System industry for high-pressure fittings are ISO and NPT threads. Although they might seem interchangeable, the two threads are used in entirely different high-pressure applications. Read on to learn more about the difference between ISO and NPT threads as we explore Hy-Lok’s extensive inventory of high-pressure fittings.
ISO vs. NPT
ISO threads and NPT threads appear to be exactly the same in terms of size and dimensions; however, they are used in majorly different applications. ISO threads are similar to British Standard Pipe Threads, which can be found in equipment worldwide. NPT fittings, however, are only found in fluid systems in North America.
Even though both threads provide similar functionality, the variances in the thread pitch in both fittings will result in leaks caused by improper sealing between the pipe and the fitting. This is highly hazardous to both your crew and the equipment used.
To avoid exposing your machines and workers to such risks, it is crucial to know the type of equipment used and the measurements of the existing fittings to find an identical replacement. Hy-Lok’s inventory of fittings covers all the necessary parts you might need for high-pressure NPT fittings.
