if you have a butaine tourch heat up the pipe the push the rubber thing into the pipe
but if you dont have a tourch put the rubber thing in the freezethen stick it in
funny
the pipe goes in the coupler
not the coupler in the pipe
sheograth
try putting the coupler in boiling water to heat it
- don't use a torch -
and some lube on the pipe
you could also round the sharp edges in a bit
but w/o altering the groove for the zip-tie
are you sure that you have the right size coupler?
