COUPLING PREPARATION
The 1906RSCHH (restrained coupling for HDPE to HDPE connections) comes factory pre-assembled
ready to be installed; however, there are a few points to check out prior to installation:
1. The bottom tie rod nuts may have backed off during
transportation. Hand tighten them prior to moving the
coupling off its pallet.
2.
(6) 2”x4” wood spacers are placed in between the glands
and the mid ring of the barrel, (3) each side. These keep
the
glands
stationary
during
transportation
and
throughout the positioning of the coupling during
installation. Ensure that these are securely in place. If
one has come out put it back in place.
3. Look inside of the coupling to check the gaskets as they
may have migrated inwards during transportation. If they
have to the point where the coupling will not fit over the
pipe, sling the coup
l
ing and lift it up off the pallet. Take a
rubber or plastic mallet and pound the gasket back.
Should this not work, back off the respective gland nuts
and try again.
