As of this writing I used the poppet with the red ring for about 120 minutes of blissfully easy breathing diving before disassembling to check the condition - which was a nice uniform orifice mark.
Need:
- Old poppet
- LP seat
- 8mm OD brass thin wall tubing (Replacement Tubes for Guardian Pen Kits: 5 Pack at Penn State Industries)
Directions:
- Carefully grind off the thickness of the new seat from the seat end. It is important to keep this square. I used a benchtop disk sander and square. Caution the part gets really HOT fast. Dunk it in water after every few seconds of sanding. If you let it get too hot the brass seat support will unglue from the poppet. You should grind off almost all the way through the brass seat support. It is OK if you see plastic in the center
- Cut a ring of brass tubing, sand the edges, and use a little RTV to glue it in place
- Apply a tiny amount of RTV silicone (100% silicone) to both the tubing and the metal seat base. Push the LP seat into place and let cure.
