Quick kitchen sink question

I just replaced old, not done correctly, piping under my kitchen, including the strainer basket. I used PVC. Everything is fine except the basket to the first piece of drainpipe has a very tiny slow leak. The washer that came with the basket is hard clear plastic. Does anyone know if/where I could find a rubber replacement? I think this would solve the issue but I can't find just a rubber washer for the application. Or will any washer do?

This would be the washing that connects the basket to the 1 1/2 pipe.

The only place I know has rubber here is Lowe's. It's called a tailpiece washer.

It's leaking because of misalignment, a plastic washer will work without leaks.

Try relieving stress off of the vertical tailpiece by loosening all joints. Using a new washer, tighten the tailpiece to the strainer first, then make your horizontal connections over to disposer or other.

I used PVC.
Do you mean schedule 40 pipe and solvent cement joints or PVC tubing with slip joints. Schedule 40 can be a lot more difficult to align so it won't leak. Any time I encounter a drain done with schedule 40 I cut it out and replace with slip joint fittings.

Unlike Brian, I never use the provided plastic nut at the strainer. It just seems the threads don't mesh perfectly and will slip. I use a metal nut over the PVC tailpiece. Good solid attachment, metal to metal.

You are not unlike Brian I was talking a rubber tailpiece washer.

It's true a standard plastic slip nut will not thread onto a strainer basket, the basket comes with a brass nut or you can purchase one.
