I need a straight line and a 90* compression fitting for the waste pipe in the kitchen.  

Would this:
https://www.screwfix.com/p/mcalpine-t28m-straight-connector-white-40mm-x-40mm/71314  

Fit this pipe:

It has an outside diameter of 43mm,  but the retailers and the manufacturer label it as 40mm 

Solvent 40mm pipe = 43mm 
Push fit 40mm pipe = 41mm  

I want to use a compression fitting for ease of use and dismantling.  Are all "40mm" compression fittings suitable for 43mm pipe?

    40mm is the inside diameter, the outside dia. depends on manufacturer and thickness of the wall.
    Most push fit fit other makes but keep your receipt just in case.  
    I think Mcalpine made pipes that only their fittings fitted.
