Thanks! No instructions in the box.... what do you use in place of teflon tape?


Teflon is not a problem I use it all the time. Leave the first thread exposed and wrap it tight with no more than two wraps. You can use a paste sealant also. If your cracking pumps you must be tightening them like a Gorilla.
