My son just moved into a townhouse, he has a delta faucet that leaks ,
got the kit. How to remove the round ring that must have been
tightened by a gorilla. Is there a trick. or a special tool. This is
under the handle that an allen wrench took off.

Wrap it with a couple of layers of cloth and grab a pipe wrench or channel
lock pliers.
