Source for replacement one-way "duckbill" valve for waste outlert

Following my tackling the whiff from the kitchen sink, the silicone insert non-return/one-way valve is f***ed.

Does anyone know if it's possible to buy just the valve, without the containing pipe ?

Not something you normally see in the UK (water traps being preferred), so no, not seen any.
