Need some help finding a replacement O ring

[spiderman097]

My protein skimmer reactor is leaking, it's an ASM GX-2 and the seem where it starts angling up is leaking. Just need some help finding a source for a replacement O ring, and I've looked but I can't seem to find the information regarding the size of the O ring. If anyone has any experience or knowledge, I would greatly appreciate it.

thanks,
Thomas

not sure what size it is but i replace a lot of o rings not just for aquarium stuff...if u take it to ace hardware they have a drawer in the back and u basically lay the o-ring on a laminated picture of different sized o-rings til ya find the size that matches...not sure their range of sizes but seemed like they had plenty when i was there last

I'd go the hardware store route. You can problably measure it and call ahead and ask if that have that general size and get the exact one.

MSC Industrial (off FIB) has tens of thousands. The biggest thing is you need to measure the size so you can request the right number. They have every common size in many different materials (rubber, silicone, viton etc). I needed one for a large skimmer, and the o-ring from the skimmer maker was $10, I bought a bag of five for $2.
