Tube Fitting Expanders
Tube fitting expanders are components commonly referred to as "expander fitting". They are attached to a single bolt hole castors so they can be attached to tube frames.They fit inside a round or square hollow tube. When the threaded stem is screwed in, the expander expands and is pressed firmly against the tube inner wa...ll.
To select the right expander fitting you need to know the inside diameter of your tube and select a round or square expander that suits your tube. For example, if the inside diameter of a round tube is 22mm, simply select a round expander that expands from 21.5mm to 24mm.
