The two flanges are tightened by four threaded studs. On each is placed a few gears — holes in them is significantly larger than the diameters of studs. That’s the whole design. Fixture screws onto the steel rod, inserted into a pneumatic or electric drill, and an air purifier is introduced into the rusty pipe. A few minutes — brown colouring of its internal parts is replaced by a metallic luster.
