As a supplement to the series D10000 tool kits,
the series D12200 tool kits (fig. 6-29) may be used.
The newer type of tooling is smaller in size and is
designed to repair tubing on board aircraft.
The portable hydraulic power supply D10004
(fig. 6-27) generates 5,500 psi to operate the swaging
tool. Hydraulic fluid is fed to the tool through a
1/4-inch quick-disconnect, high-pressure hose. As a
precaution against premature tool fatigue, the
swaging pressure is kept from exceeding 5,500 psi by
the pressure relief valve. The D 10004 hydraulic
power supply can be operated either manually by

using a hand pump or automatically by
air-to-hydraulic fluid intensification from a 80 ±20 psi
pressure shop air source.
Dynatube Fitting Repair
Dynatube fittings consist of a threaded male
connector, a female shoulder with a machined beam,
and a nut (fig. 6-30). Compared to the five
components in a standard MS fitting, the three
components in a Dynatube fitting are smaller, lighter,
and have fewer potential leak paths. Dynatube
fittings can be connected to rigid tubing by welding,
but internal mechanical swaging with Resistoflex
