Footnote
The normal swage length, for standard length stems and ferrules, is obtained by terminating the swage when
the top (outboard) holes completely pass into the lead portion of the die. In other words, when the face of the
pusher meets or touches the face of the die, the swage is complete. When using long length stems and ferrules,
it may be necessary to terminate the swage sooner. If rubber starts to extrude out of the top (outboard) holes or
the top (reservoir area) of the ferrule begins to swell before the normal swage length is effected, stop the swage.
The Ram pressure gauge provides another guide for correct swaging procedures. All Rams are equipped with
pressure gauges. These gauges provide a line pressure reading in PSI (Pounds per Square Inch). For example:
the 100 Ton Ram includes an electric motor driven hydraulic pump capable of developing 10,000 PSI. The area of
the piston head of the ram cylinder is 20.6 square inches. Thus, our maximum ram force is 10,000 x 20.6 or
206,000 pounds, which is equivalent to approximately 100 tons.
All hoses of one size and style should require approximately the same ram force for swaging. However, since
the Ram is intended for use with a variety of hoses of varying constructions and hose wall thickness, we therefore
cannot provide a chart of recommended pressure gauge readings. Dixon strongly recommends the recording of
data such as hose type, I.D. size, O.D. measurement for each end, ferrule used each end, die used each end
and pressure (PSI) required to effect the swage on each end. The Ram user, with this database and his/her
experience, will consistently produce quality hose assemblies.
General Guidelines
1. This manual supersedes all previous instructions for the 100 Ton Ram.
2. Operator(s) should wear safety apparel such as safety glasses and steel toe shoes when
operating this equipment.
3. The Holedall Coupling System and the procedures in this manual are an engineered system.
Skipping or eliminating steps in the procedure, unless directed to do so, can lead to an assembly failure.
4. Do not “mix and match” stems, ferrules and accessories from manufacturers other than
Dixon Valve & Coupling Company.
5. After assembly is complete, pressure test the assembly in accordance with Rubber Manufacturers
Association (RMA) specifications.
