I recently won an auction that includes a Scubapro 109. I already have one but this came with a MK5,so why not. I had gotten a Duro poppet upgrade for that 109 so I could replace the LP seat as needed. Wasn`t really looking forward to spending $25 plus shipping for another upgrade. I got to looking at an old poppet from a G250 I had upgraded. This is in the first pic
In the second pic I unscrewed the metal stem and removed the old poppet LP seat.
To get the spring to the right tension and to keep it centered I notched the old poppet to match the Duro seen in #3. The wings are slightly different but work OK.
In #4 you can see the seating areas compared. They are not identical, but will be sealed by the LP puck type seat.
#5 shows the seats in place and the last shows the homemade upgrade with the original.
I`ve installed and tested this and it breathes just as good as the Duro. A nice repurposing of a spare part. I don`t know if this has been done before, but it was new to me.
