ISO flanges and piping can be used in various applications that involve frequent installation and removal, from atmospheric pressure to high vacuum. Generally, the diameter of pipes exceeds 50 mm (2 inches). If a fluororubber O-ring is used, it can withstand baking at 150°C. ISO250 refers to a 250 caliber, with an ISO interface; ISO100 refers to a 100 caliber, also with an ISO interface

It should be an ISO reducer fitting, with pipe diameters of 250 and 100 on each side respectively
