External Swage High Pressure Couplings
Holedall Internal Expansion Couplings
Stem and Ferrule Complete Assemblies
Applications:
These couplings are for services requiring a fitting which will withstand extremely high pressures (up to 3,000 PSI at 70°F) 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.
Applications:
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.
