* ASSEMBLY PROCEDURE For 2 1/2” THREADED MALE STEMS:
In order to prevent possible thread collapse on 2 1/2” Male NPT Stems during installation, it is recom-
mended that a female threaded adapter be installed prior to installation. The adapter part # is M011-384 for
the 2 1/2” male stem. Following is the procedure for installation:
1. Lubricate stem ID and small end of expansion plug.
2. Thread M011-384 onto threads of the male stem hand tight ONLY!
3. Slide stem over pull rod thread adapter end first.
4. Seat M011-384 onto OUTER recess of the adapter.
5. Follow normal IX procedure.
6. When the assembly is removed from the pull rod, remove M011-384 and clean the stem ID of
excess lubricant.
If you have any questions, please feel free to contact our Engineering Department.
Dixon Valve sells Steel Internal Expansion Fittings and Stainless Steel. Verify that the correct plug and
adapter plates are being used when installing fittings. Also note that with food grade fittings a different
lubricant may be needed. If you need assistance please contact your Dixon Representative or call any
Dixon Branch.
Dixon Valve and Coupling Company recommends that all
hose assemblies be tested as recommended by the Rubber Manufacturers Association.
Slide the hose with the ferrule on over the shank until
the ferrule contacts the shoulder of the stem. Make
sure you align the ferrule with the second mark from
step 6. Make sure the pocket has been maintained.
Important! If there is an insufficient pocket for the
rubber to displace into, damage may occur to the stem,
ferrule and/or hose.
While holding the hose and ferrule firmly against the
stem shoulder, engage the Ram by stepping on the foot pedal
(or depressing the “ON” button on the remote control.) The
internal expansion operation is complete when the hose and
stem assembly is pushed completely over the internal expan-
sion plug. Release foot pedal or “ON” switch.
Note: If the gauge reads 10,000 PSI before internal expansion is
complete, stop. Contact Dixon for further assistance. During
internal expansion never stand directly in front of the Ram.
Visually inspect the coupling and clean excess
lubricant from the stem I.D.
