I recently replaced the o-rings and bulkhead fittings on a Hayward filter housing (C3020 filters) to fix a leak.

Unfortunately, the leak is still there (about 1 drop per minute) and I think it's because I wasn't able to fully tighten the 3" lock nuts.

What is the best tool to use to get a good grip on the lock nuts?

Should I be using teflon tape or ??? to get a better seal?

If you’re talking about here(circled in yellow) yes use Teflon tape and a pair of channel locks to tighten.
