Leaky pipe - replacement needed?

[Lnd89]

Hello. Have developed a leak in the pipe under my sink. Have used LS-X to glue the pipes together, but there is still a tiny drip. There's no cracks in the pipes, they're good as new so think it's how they're fixed together. Is there something else I can try? Please see photos attached - photo 1, what it looked like before, photo 2 - what it looks like now. Thanks!

Cut out and renew section. What’s the grey pipe to the right, a reducer?

Looks like an Ikea waste ?

Yes, it's an Ikea kitchen. Any advice? Was thinking of trying repair tape and/or fiberglass wrap. Not sure if silicone or rubber tape is better? Thank you!

Grey pipe to the right goes directly to kitchen sink. That just slides in and doesn't seem to be too much of a problem. It's more the two I've tried to glue as it's pressured into an angle once everything is connected. Thanks!

Cut the grey solvent weld socket off and use a mechanical straight to join the waste to the Ikea fitting
