How To Order
Donuts can be ordered by giving the size, material and type of
connection you want to make. Donuts require specic information
on the manufacturer of pipe. Our sales coordinators are trained
to assist you.
Donuts can also be ordered by dimensions.
Donuts seal by com-
pression and have much less dimensional range than couplings.
