Accurately measure the hose O.D. with a diameter
tape. Select the correct Holedall Petroleum Ferrule
from the DPL based upon the Hose O.D. just
measured.
Note! Always measure both hose ends for accurate
ferrule selection.
Make sure the hose end is cut square. Slide the
ferrule over the hose until the turned over end of the
ferrule contacts the end of the hose. Place a mark
on the hose at the junction of the ferrule and hose.
Move the ferrule away from the hose end 1/8” and
place another mark at the junction of the hose and
ferrule. This will insure that the proper rubber
displacement or pocket is maintained during the
expansion process.

Screw or slide the IX plug, small end first, onto the
Pull Rod and into the shank of the stem. For 2” and
above screw the retaining nut on until it contacts the
plug. Move the stem slightly to allow for slack and
hand tighten the plug or nut until it is snug.
Slide the stem over the Pull Rod and into the recess
of the Thrust Plate with the connection side of the
stem facing the ram. For male stems, insert the hex
into the recess of the Thrust Plate. For female
stems, insert the first hex into the Thrust Plate so
that the second hex will fit into the recess of the
Thrust Plate.
Note! There is no need to lubricate the plug or
stem. The stems are pre-lubricated at the factory.
