HEMPER A-Dab-TER | Silicone Vape Pen Adapter for Water Pipes | Round & Flat Tips (Black) https://www.amazon.com/dp/B07TJNQZQV/ref=cm_sw_r_cp_api_i_rMHZDbRXHNB49
This is the setup i use. Unlike the dabcap or the fat MP, this one stays on your glass so you won’t have an ugly MP stuck on your dynavap all the time.
I bought this on amazon based on a recommendation from another thread:

It works great with a v4 and hydratube from my evo.
