Does anybody know how to bond PP to ABS?

Hi Allidila...

PP, for polypropylene, right? You CANNOT bond ABS to PP... not that I know of anyway!

The only way I know to connect PP and ABS would be to purchase a MALE x HOSE BARB threaded adapter and some hose clamps, heat the PP a little and insert the hose adapter and then tighten the clamps. Install teflon tape and/or pipe dope to the male threads and then screw an ABS female adapter onto the male threads and you have successfully transitioned over to ABS... See image below.

This is not a common transition, so tell me, what exactly are you trying to do?
