Internal Expansion:
Dixon recently received a report of a situation concerning the installation of 4"
Internal Expansion Male Threaded Stems (IXCM64). The fittings were installed
using a 25 Ton Ram with the 25IXATTACH. At the base of the 25IXATTACH is
the 4" Adapter. Over time this adapter end can wear. This wear can cause the 4"
IXM64 stem to collapse at the threads during the installation process. This
happens because even pressure is not applied on the threads as the stem is being
expanded.
The situation can be corrected by using an adapter designed for the 4" fittings.
This new part number is M011-385. Unlike the adapter designed for the IXM40's,
this adapter is recommended only if the 25IXATTACH has a worn plate. It is not
a requirement that it be purchased to do 4" IX Stems.
