Is this the right seal for this p trap?

Leaking from the cone shaped end. Is that the correct seal? Shouldn't there be one on the cone side? I can't see how this seals anything when the water just travels from the pipe through the threads of the joint.

No, that's a ground-joint p-trap -- it doesn't use a washer on the conical connection. I'll put a little pipe dope on the 'cone' and make it tight. If you don't want to mess with it, you could get a flanged non-ground-joint trap to use instead..

I agree, do NOT use those washers. The squishy rubber will make it difficult to turn the nut tight enough to prevent leaking. When making the connection make sure that both sealing surfaces male and female are clean and smooth.

OK I'll remove that washer. The p trap is new but the pipe from the wall is 50 years old so won't be perfectly smooth. Hard to believe there is no gasket between two metal pipes. Will add some RTV sealant.
