Fittings 101: International Seals

In this video, we cover the characteristics, applications, and advantages of various international seals commonly found in metric and British threaded tube fitting and adapter designs. You’ll learn the differences between parallel and tapered thread designs, how sealing methods work, and why different seal types are used in hydraulic and pneumatic applications. This video also explains common sealing solutions like bonded seals and captive seals, including how they create leak-tight connections and where they are most commonly applied. Understanding these sealing methods can help improve fitting identification, system reliability, and overall performance in high-pressure applications.
