Sealing plugs apply to a number of through-coolant holder designs. A number of holders are of the ADB through-coolant design. For B through coolant (flange through coolant), the two originally fitted sealing plugs in the holder’s flange have to be removed, and a non-through-coolant pull stud must be used to seal the back of the holder.
For AD through coolant (central drawbar through coolant), the two sealing plugs in the holder’s flange have to be in place, and a through-coolant pull stud has to be used.
Sealing paste required for sealing plug mounting is not available from Seco-EPB; we recommend ’LOCTITE 577 - Thread sealing paste’.
