The PLUG DIAMETER (H) must be figured using the minimum
clearance gap as given in Figure 20 and the maximum clearance
gap as shown in Figure 22. The plug diameter can also be
calculated by subtracting the minimum gap from the minimum bore
giving the maximum plug diameter. The minimum plug diameter can be
calculated by subtracting the maximum gap (see Figure 22)
from the maximum bore dimension. By using this method, it allows the
use of softer compounds without the possibilities of encountering
extrusions.
