Across all industries and sectors, a lot is riding on a fluid system’s high-pressure fittings. Often, these fittings play a vital role in keeping your process or fluid system safe; routine maintenance, repair, and replacement are critical to your operation’s success.
When the time comes to replace your high-pressure fittings, it is critical to ensure you have the right parts for the job. Two of the most common specifications in Canada for high-pressure fittings are ISO and NPT threads. Although they appear similar, the two standards are wholly incompatible in high-pressure applications. Read on to learn more about the difference between ISO and NPT threads, as well as Hy-Lok’s extensive inventory of high-pressure fittings.
ISO vs. NPT Threads
ISO threads are identical to British Standard Pipe Threads. Although they may appear identical to NPT threads in size and dimension, they feature a slightly different pitch (distance between threads).
Why does this matter? Especially in high-pressure applications, variances in thread pitch often result in an improper seal, leading to a compromised connection, leaks, and ultimately safety hazards for your personnel and equipment.
Generally speaking, ISO-compatible fittings can be found on equipment manufactured around the world, whereas NPT fittings are usually only found in North America. With the wide variety of equipment found in Canada, it is imperative to know what types of fitting your fluid system needs and ensure any new or replacement parts are compatible.
