Tuning FX Impact M3 Bottle Connector Socket Size?

[nirinium]

FX Impact M3 Bottle Connector Socket Size? Anyone have any idea what socket size the bottle connector is? I need to remove it to replace first regulator o-ring.

I tried just an adjustable wrench, but I felt like I was gonna scratch the body all up so I backed off. I've read 15/16ths, but measured it with calipers and it was ~23mm.

Just wanna know what I need to get for sure because I don't have any deep well sockets and I will need to purchase to remove. I have highlighted what I'm talking about below in the diagram, D97.

Any help would be greatly appreciated. Thanks.

Go to about 9:30 to see. it's a 24mm 6 sided socket and don't forget the protection for the main block, even cut-out card stock will work.

Go to about 9:30 to see. I think it's a 22mm socket and don't forget the protection for the main block, even cut-out card stock will work.

Sorry, and I don't think he actually states the size... I'll check when I get downstairs, I'm sure someone will beat me to it.

From what I can see it appears to be a 24mm socket in the video (I could be totally wrong) if you find out for sure let me know.

Really appreciate the assistance on this. Gotta make an o-ring order now...

It is a 24mm socket BUT you need a 6 sided one as the 12 point one will not fit.

My two M3 have different size bottle connectors. The earlier M3(May) is 24mm. But it's better to use a 15/16 inch six point deep socket. The later M3(August) is 23mm, and you can only use a 23mm six point deep socket. 

The M3 1st regulator piston is the same one as M3 2nd or MKII regulator, the o-ring size is 4*1.5 NBR70. Replace it If you have leak from the small hole on bottle connector. 

The M3 1st regulator adjust screw o-ring is 2*1.5 NBR90. Replace it if overnight you 1st reg pressure increase to almost same as bottle.

To remove/reinstall the bottle connector, you can either use a 3/8 ratchet or an impact driver like Dewalt. First time remove will be much easier with an Impact driver. The 23mm connector was super tight on my M3, couldn't loose it by hand. I just fold a Kirkland paper tissue twice, cut a hole, perfect protection for block.

I used a small electric impact with 15/16 socket. Started off trying with it in a vise and using a ratchet, but didn't like the torque being applied. It came out easy with careful use of the impact.

I finally have a wika gauge on the 1st reg so I'm going to get to the bottom of what is actually going on.
