Dixon Valve 25 TON RAM SEC01 Holedall Fittings - Manual (Page 10)

External Swage High Pressure Couplings
Holedall Internal Expansion Couplings
Stem and Ferrule Complete Assemblies
These couplings are for services requiring a fitting 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 fittings 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.
The Dixon Internally Expanded Couplings are essential when maximum flow is important. Only one expansion tool is needed for
each hose ID Some recommended applications of these fittings are: concrete pump hose, plaster and grout hose, oil suction and
discharge hose, multi-purpose heavy duty air hose, jetting hose, barge loading hose and bottom loading hose.
Benefits of Internal Expansion Fittings:
• maximum flow of media
• reduction of turbulence through hose
• excellent sealing and retention characteristics
• outperforms band clamps
• easy and consistent installation
End Configurations Available:
• male NPT
• raised California
• victaulic
• others available on request
Cross-section of Holedall internally expanded assembly
Dixon Holedall stems and ferrules are specifically 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.
