These are the replacement O-Rings for the Polarstar Fusion Engine.

1x Poppet Base
1x Poppet Retainer

Disclaimer: If you do not know which poppet sail o-ring to utilize, please take your original o-ring from your poppet sale and compare it to the new o-rings. You should be able to match it up to the one that you need. You will find that the older poppet sail o-ring (015-70) is noticeably thicker than the newer poppet sail o-ring (15x1.5mm).
