Fitting Assembly
3.1
Assembly Tool Selection
Select the correct size tool (noted on face of tool) and pressure class
assembly tool (denoted by color — see Table 2), P/N RTSTX-01-SIZE,
where the "X" denotes the pressure class of the fitting. The installer
must note the color coding of the fitting "ring" and match this with
the color of the movable jaw on the assembly tool.

Assembly Tool Pressure Connection
Attach the flexible hose with the mating quick disconnect cou-
pling to the nipple at the bottom of the tool, and the nipple end
of the hose to the mating quick disconnect coupling on the por-
table pump. The pump may be a hand pump, Aeroquip brand
P/N 10-00400A, a foot-operated air/hydraulic intensifier, Aeroquip
brand P/N 10-00401A or a switch operated air/hydraulic intensifier,
Aeroquip brand P/N 10-00402TA.
3.3
Tool Installation
With the fitting positioned onto the tube as described in Paragraph
2.0, align the assembly tool to one leg of the fitting, with the "ring"
nestled into the movable jaw of the tool and the front opening of the
tool bottomed into the fitting body, as shown in Figure 5A. The tool
is designed to access the fitting leg from any radial angle as required
by the space available.
3.4
Tool Pressurization
Apply 8000-8500 psig (551.58-586.05 bar) hydraulic pressure to the
tool to advance the fitting ring to complete the assembly process as
shown in Figure 5B. Tool pressure is typically in the 8000-8500 psi
(551.58-586.05 bar) range, regardless of fitting size or pressure class,
however enough pressure should be used to advance the ring to the
full forward position. Once the ring has been advanced, no further
pressurization is required.
Note: Fitting must always be fully nested into tool to maximize tool
life.
Note: See Section 6.2 for special consideration in swaging pres-
sures when using special "Reversed Tools" with reducer/expander
fittings.
3.4.1
Pressure Level
If using the hand pump, the 8000-8500 psig (551.58-586.05 bar)
pressure level is assured by the pressure gauge reading. If using a
foot operated air/hydraulic intensifier or a switch operated air/hydrau-
lic intensifier, the intensifier will automatically stop when 8000-8500
psig (551.58-586.05 bar) is reached.
When the pressure is released, the movable jaw will return to its
original position.
