Rams securely attach Holedall couplings to hose. Five machines meet every hose service requirement.
Rams, are powerful nely engineered machines designed specically to swage and internally expand Holedall couplings by
hydraulic pressure. Since each ram generates all the hydraulic pressure required to attach the Holedall coupling, one person can
easily operate the equipment.

Bench mounted model (optional stand available), producing
up to 10,000 PSI, for up to 15 tons of ram force. Capable of
expanding 1" through 3" steel ttings and ¾" through 4" brass
Holedall Petroleum ttings. The motor is ½ h.p., 115 volt 60
cycle, single phase with foot pedal.

100 Ton Ram
Used for swaging Holedall ttings to hose from 1¼" through
10" ID With optional accessories, this ram may be used for
internally expanded couplings on hose from 1¼" through 6".
This machine is capable of producing up to 100 tons of ram
force. A 1-1/8 h.p., 115 volt, 60 cycle, single phase motor is
standard with remote, (220/440 volt motors are available).
350 Ton Ram
Free standing model producing up to 10,000 PSI of line
pressure for up to 25 tons of ram force. Capable of external

speed pump kit option is available.
50 Ton Ram
Used for swaging Holedall and Rotary ttings. This ram is
capable of producing up to 354 tons of ram force for swaging.
Bench mounted model (optional stand available),
producing up to 10,000 PSI, for up to 50 tons of ram force.

equipment. A 1-1/8 h.p., 115 volt, 60 cycle, single phase motor
is standard with remote, (220/440 volt motors are available).
All Rams require dies of the proper size to reduce the ferrule to the proper diameter for a good grip on the hose. Pushers of the
proper size must be used on the end of the Ram to push the Holedall tting through the die. Die and pusher selection depends
on the sizes and types of hoses being coupled. Ferrule recommendations and a Die Chart binder are available upon request.
Consult your Dixon representative for specic details.

Holedall couplings, regardless of coupling style, are never to be used for steam service at any pressure. Holedall ttings listed
below are not to be used with cable reinforced high-pressure hose, 4 or 6 braid wire hydraulic hose or any other service not
listed in recommendations. Consult factory for recommendations on usage.
Holedall couplings, to perform satisfactorily, must be applied properly in accordance with Dixon's assembly procedures, using
correct die and ferrule for that particular hose end OD Dixon's Die and Ferrule Recommendation Guide is to be used to select
correct dies and ferrules. If you do not have the updated Die and Ferrule Recommendation Guide, consult the factory.
K
Note: Hose service working pressure (including surges and spikes) is never to exceed the maximum recommended working
pressure for the tting (reference chart below)*. King safety cables are recommended. Media being transported through the
hose should be compatible with the stem material and ferrule material. Consult Compatibility Chart on pages 548-553 or the
factory for material compatibility. For applications other than the ones listed, please consult Dixon factory.

1) The hose rated working pressure, or
2) The coupling rated working pressure
** For hoses which use IXF48-3 to IXF48-5 and IXF64-2 to IXF64-5, consult the factory for working pressures.
See notes below for specic recommendations.

Holedall
Holedall External Swage Coupling System
The Holedall coupling system provides outstanding strength, durability and safety.
The Holedall system is a method of attaching couplings to hose utilizing a progressive swage. The patented Holedall
couplings include a Holedall stem and a specially engineered ferrule. The hydraulic swaging of the coupling to the hose is
accomplished by pushing the ferrule through a die which reduces the ferrule OD The ferrule penetrates the hose wall, providing
a 360° uninterrupted compression band around the hose.
A hydraulic ram is the only piece of machinery necessary to accomplish the coupling. Available in ve different sizes - 15, 25,
50, 100 and 350 ton - these rams will accommodate dies and pushers of various sizes so that hoses up to 10" in diameter may
be coupled.
This multi-purpose, high pressure coupling system requires no bolts and results in a clean coupling with no protrusions. The
swaging operation is fast and hose of various lengths and different styles can be coupled. Ease of operation, exibility and
economy make the Holedall method an unequalled assembly system.
The Holedall coupling - the most adaptable coupling available.
For almost half a century, Holedall couplings have provided long-lasting efciency and safety unmatched by any other
industrial hose tting.
Couplings are available in stainless steel and carbon steel.
Couplings are furnished with pipe thread, plain end, victaulic grooved or anged ends.
Dixon Holedall stems and ferrules are specically designed to be used together as a coupling system.
Due to differences in dimensions and tolerances, for safety reasons,
do not use other manufacturer's stems or ferrules with Dixon Holedall products.

Stainless External Swage Ferrules
Light duty 304 stainless ferrules for use with standard length
stems such as the TMR series. Consult Dixon for die
recommendations. Refer to the Dixon Pressure Slide Chart
for specic pressure recommendations.
• The largest advantage of the notched design is that the coupling can be removed from a damaged hose by cutting away the
ferrule, without necessarily damaging the tting. After inspection of the tting to determine its suitability for reuse, it can be
reinstalled into another hose by using a new ferrule.
• The notched system allows you to better manage your inventories. You can stock one stem and two ferrules, and cover the
same hose range with less inventory. You must purchase a stem and the matching ferrule to create an assembly.
• For hose outside diameters of 2-4/64" and below, the couplings are crimp only.
• For hose outside diameters of 2-5/64" and above, the couplings can be crimped or swaged.
• See page 22 for cam and groove style notched NOS ttings.
Only use the NOS shank with the NOS ferrules.
Due to differences in dimensions and tolerances for safety reasons, do not use other
manufacturer's stems or ferrules with Dixon Holedall products.
Designed for smaller hose systems, these couplings may be
used for hose ID's of ¼" - 1" and come complete with factory
assembled stem and ferrule combination.
These couplings are for services requiring a tting which will withstand extremely high pressures (up to 3,000 PSI) and severe
operating conditions, such as on small and medium size drilling rigs, used for slim hole, core drill, workover, seismograph, water
well, blast or shot holes, etc. These long, rugged ttings are machined from seamless pipe and tubing with specially designed
serrations. The mating ferrules are machined from heavy wall material incorporating matching serrations. These couplings are
shipped with matching ferrules. Please provide hose OD when ordering for properly sized ferrule. Make sure both ends of the
hose are measured for OD. Must be swaged with 50 Ton or 100 Ton Ram.
* An accurate hose OD must be provided to complete the part # and to ensure proper retention.
• The LM ttings are sold as a complete coupling, including stem and ferrule.
