Here are parts and o-ring sizes you can use instead of an AquaLung service kit (since the dealers won't sell them to you even if you're certified)
This does assume that you already know how to service the Legend and just can't get parts kits.
First Stage:
HP Seat: Trident A244
Diaphragm: Trident A163
O-rings are listed as: AL Part # / O-ring size. I used 70 duro for everything, haven't had any issues. I found the easiest place to get all the o-rings in one place is actually Amazon (especially because of the 001-1/2 o-rings). The backup rings I could only find in 90 duro and that seems to match the factory ones based on feel. Also got them on Amazon.
824407P / 013
119129 / 005 Backup Ring
820080P / 006
820038P / 011
820011P / 011
820009P / 009
The only thing I can't find for the second stage is the ACD filter. If anyone knows who makes them please share! I run mine through the ultrasonic cleaner and reuse the filter. No issues so far.
Second Stage:
LP Seat: Trident A148
O-Rings listed as AL Part # / O-ring size
820015P / 015
820010P / 010
AP1438P / 019
AP2041P / 001-1/2 (this size is not a typo, it's just a strange size)
820306 / 006
820014P / 014
820011P / 011
For the Legend Octo, see my post about the AquaLung Core 2nd stage. They're the same.
