TUBE COUPLING INSTALLATION
Tube and tube fittings are connected by wrap-around
couplings which clamp by means of a tapered, hammer-
driven lock member.

Coupling
Lanced Clip
When assembling coupling, the wide end of
the slide bar moves toward the lanced clip

Orient coupling so that the impact
block is above tube centerline.
Figure 8a. Coupling Assembly
To assemble the coupling, hook the free end of the
coupling sleeve into the lanced clip. Place the wide end of
the tapered slide bar on the coupling so that it moves
toward the lanced clip. Insert the two tube ends into the
coupling. Be sure the tube ends are in line and are flush
against the stop pins inside the coupling.
Hammer-drive the slide bar until the coupling is secured
snugly to the tubes. Overdriving the slide bar will distort
the coupling or slide bar lip and will decrease the holding
capability of the coupling. Coupling should be tight when
the slide bar is ± 2" (5 cm) from the end of the coupling.
See Figure 7a.

Impact Block
Use a 4 ft. (1.2 m) level as indicated to establish pitch
of tubing and to ensure that tubes fit squarely at ends.
This in turn will ensure the proper fit of couplings.
