### Description

 

The Type “C” Equalizing Plug is an equalizing sub that holds pressure generated from the bottom only. It can be used as a pump through plug if needed. When used in conjunction with the Type “B”, “H”, and “F” Equalizing Subs, the upper end of the bean housing serves as a valve which seats and seals on a tapered seat that is present in all Type “B”, “H”, and “F” subs. This same tapered seat is present in the “B” and “W” Mandrels so that the “C” Plug could be used on them without another equalizing sub made up to it. The bean has a secondary valve which sticks out above the bean that must be pushed off seat, using an  
equalizing prong made up the the proper pulling tool, in order to equalize. This is accomplished by applying tool string weight on it prior to pulling the locking mandrel.
