Hi all, and thanks in advance for any help. I'm having trouble finding replacement parts for some damaged adapters. We have a two-basin sink, so a simple NPT x hub adapter isn't ideal, for maintenance/easy removal reasons. It is a gasketed compression fitting, wherein there is a lock nut slotted into a gasket zone. The lock nut would thread onto the sink drain, compressing the gasket seal. Can anyone give me the name of the pictured part?
