I am using no hub couplings to connect drain pipes and the couplings are
made of stainless steel clamps with a 3/8" hex head with specifications
called for tightening to 80 pound-in.

I have a torque wrench that will tighten to 60 pound-inch and then releases
but not 80, and I don't want to pay a lot of money to for a 90 pound-in
torque wrench just to tighten 2 couplings and will not have a use for it
ever. Is there any trick anyone can think of that would allow me to tighen
to that specification?

Thanks,

Use an extention to increase the leverage between the click mechanism
and the screw head. Or use a pull scale on the end of a wrench and do
the calculations for length. 8 lbs on a 10 inch wrench would do it.

Besides, the torque is NOT terribly critical. I generally make them
"wrist tight" using a 3 inch ratchet or "pretty durn tight" with a
screwdriver.
