As a supplement to the series D10000 tool kits, the
series D12200 tool kits (fig. 10-53) 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.
10-51) 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 D10004 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.

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 hand tools is the authorized method for
The repair methods using Dynatube fittings are
illustrated in figures 10-55 through 10-57.
