To start, please select your tubing OD and wall thickness using Table 1.
FastSeal
™
assembly consists of the
following steps:
1. Prep

FastSeal
connections require pre-setting that can be accomplished by hand with a wrench and is best done with the
assistance of a fixed vice.
Step 1
– Place marking tool on tube
until it bottoms out. Mark around
OD as shown. If marking tool is not
available, use insertion depths shown
in Table 2.
Step 4
– Insert the tube into the
FastSeal
nut to the tube depth
mark. Twist and push tube to aid the
insertion. You will feel the tube pop
past the O-ring and bottom out.
Step 2
– Thread FastSeal nut onto
fitting body or mandrel hand tight.
This is best completed with the
assistance of a fixed vice if available.
Step 5
– Mark the nut and body as
shown to assist with the FFFT preset.
Step 3
– Lubricate the end of the tube
with hydraulic oil to help with insertion
in the next step.
Step 6
– Tighten the nut to specified
FFFT of 7-8 flats. You should feel a
perceptible torque rise around 7 flats.
2. Pre-set
A heavy deburr, per
Figure 1 of at least 1
mm on the tube is recommended to prevent
damage to the internal O-ring. Ensure tube
is clean and all chips and debris have been
removed from the tube. The deburr dimension
can be checked visually (roughly the
thickness of a coin) or with the depth gauge
on the back end of the marking tool.
