If you're unsure which poppet sail O-ring to use from your o-ring repair kit, compare your original O-ring to the new ones in the kit. The older poppet sail O-ring (015-70) is noticeably thicker than the newer one (15x1.5mm). Matching the correct O-ring is important for maintaining the integrity of your airsoft engine, preventing leaks, and ensuring smooth operation.
