COUPLING ASSEMBLY
Couplings: Tube and tube fittings are connected by wrap-
around couplings which clamp by means of
a tapered, hammer-driven lock member. The
starting ends of the coupling and lock member
are identified by 1/4" holes which are put
together when starting assembly. Be sure the
tube ends are in line and tube ends butt against
stop pin(s) inside coupling. The slide bar is to be
hammer-driven to a point of securing the coupling
snugly to the tubes. Over-driving will result in
distortion of the coupling or slide bar lip to a
point decreasing the holding the capability of the
coupling. (See Figure 4)
