Expander head
Ridgid expander heads widen the end of a pipe, so a second pipe of the same diameter can slide into it. Installers use them to expand pipes by hand and make a joint without a separate coupling.
Each expander head is made for one pipe diameter. The range runs from 8 mm to 45 mm, with sizes in between such as 10, 12, 14, 15, 16, 17, 18, 20, 22, 28, 35 and 42 mm. Choose the head by the outside diameter of the pipe you want to expand: a head that does not match exactly gives a joint that is too loose or too tight. Anyone who works with different diameters every day builds up a set of heads, so every pipe size is ready and no time is lost searching. Also note the sizes you use most and keep a spare of those at hand. The description always states the diameter of the head, so you can quickly hold it against your pipe size.
The expander heads belong to the cutting and bending accessories in the spare blades, snap-off blades and pipe supports category, which also holds other replacement parts for pipe work.
