Reply To: Plumber’s Putty as Thread Connection Seal

[GuestParticipant]

I don’t think it would provide a good seal. As you screw the pipe, the putty will come out of the threads. Putty is too dry/grainy for this application.

I can’t imagine why you would ask – teflon tape costs less than $1 a roll.

If you’ve already done it and it’s working, I can’t say how long it will last – but it should not cause any permanent damage.
