It's not aerosol, but you can use ordinary vegetable oil on the rubber seals, like Fernco. Crisco is also OK, but is messier and often reserved for outdoor assemblies (think new sewage pipe with the rubber donuts as seals). They sell a pipe lube for this kind of assembly, too.
When updating my FIL's home with 100' of new sewer line to connect to public lines, we bought pipe lube. When making unexpected repairs involving cutting pipe, we've grabbed Crisco to slide Fernco all the way on one pipe then slide back to cover the joint.
Veg oil is best for vertical existing couplers as gravity helps get it into the joint. A heat gun can be helpful, but only a little heat to help soften the fitting.
A small diameter blunt tool can often be worked in between the coupler and the pipe, breaking the 'stickiness' between them (rubber tends to stick after a while), which also is a too way to get the veg oil started.
Hope this helps.
