- Cast iron etc.
Hollow Plug consists of:
How to measure hollow plugs?
- Pipe Plug
- Hollow Plug Body

To get the accurate measurements of hollow plugs, the measurements of
pipe size, O-ring uniform size and dimensions are to be known. As seen
in the figure, the pipe size is denoted by P while the dimensions are
denoted by B, C, L ,A/F.
