I'm trying to get a McMaster order together to stock up.

Octane 9 with a 3 lug and 13.5 x 1LH  
Octane 45 with a 578x28

9464K72 looks like the 18 I need for the piston caps on the 9 and 45 but I can't find the sizes for the 2 inside the 3 lug.

Would appreciate an assist.

They sure look like 018s to me.  Just compared them.  SiCo customer service will verify, because can't find it documented anywhere!

Yeah I looked for hours. There is what looks to be an 18 and another that looks smaller. No worries, I'll take it out and measure or give them a call.

Thanks for looking.

Let us know if they tell you for sure what size they are

I got my lazy ass up and popped the rings out to put a caliper on them. On the 3 lug the piston has an 18 at .87 OD. The one on the inside of the body is .81 which makes it a 17 (9464K71) on McMaster.

EDIT: I made an order and will check back after a test fit.

Confirmed, they fit perfectly.

9464K72 size 18 - piston caps on the Octane 9/45 and the piston on the 3 lug.
9464K71 size 17 - Inside the 3 lug adapter body

Got a bag of 50 each for $18 shipped.
