 FIGURE 5-5
Cutting Out the
Leaking Collector
FIGURE 5-6
Removing the
Coupling Halves
If slip (repair) couplings without stops were used, cut through them with a tubing
cutter (Figure 5-5). Make the cut 1/4" from the coupling center, in the direction of the
leaking collector. This gives you a better chance to avoid shortening the headers of
the good collectors. You will very likely have to cut through both the coupling and
the leaking collector's header.
Heat and remove the half-couplings on adjacent collectors (Figure 5-6). Use a heat
shield to protect header grommets. A swing-open escutcheon plate can be used as
a shield.
