Seriously ... What are the thread specs for the 2019 Float X2 bleed port? I'd love to do a syringe bleed when I open it up, but I can't find any reliable info online on what type of adapter I need.

Did you ever attempt a syringe bleed? did it work? Thanks

Yes, and it was a disaster. Well, the bleed itself wasn't a disaster. It just didn't work. But, the whole process was a disaster.

I couldn't find an off the shelf adapter. So, I tried a couple different ways of making one, including try to drill through the middle of nylon 6-32 bolt. Turns out 6-32 is really small and hard to drill through the middle off without getting into the threads.

I've stuck with the nitrile glove plunger method, and it works ok-ish. But, I feel like somebody could make a decent amount of money selling a custom adapter on ebay.

Thanks for your reply! I just meant in theory, if you had that adaptor could you just connect that to a syringe full of oil and bleed a shock, or do you think you need to have an actual fill machine?

I have a vague recollection of seeing one of the guys on Fox Dialed doing it with a syringe. That's why I started down this path.

You can but you'll be there a long time. If you're doing a syringe bleed you start with filling the shock by hand as much as possible during assembly and use the syringe to displace final air bubbles.
If you're doing a vacuum bleed the shock goes together dry and those can take a huge number of vacuum and fill cycles to get all the air out.

Vacuum bleeding takes the air out of the oil (about 8% by volume at room temp/pressure). This means the shock can absorb a lot of air before it gets slurpy. Where a manual bleed is relying on more IFP pressure to keep air bubbles dissolved.

Do you know what’s the tubing ID it takes on the non-threaded end?

Is it preferred to bleed from the damper body port over the reservoir piston (using a vacuum machine)? I guess setting IFP depth will be just a little more tricky or messy.
Reason I’m asking is it’d be easier if I had one size fits all. Fox’s uses 6-32 quite consistenly in the reservor piston port and in the body cap/eyelet assembly (old dhx, van rc, etc). However the dpx2 damper body bleed port is a 5/16-24.

Dubro DUB-241

Thread Pitch #6-32
Total L: 12.6 mm
Thread L: 4.45 mm
Thread OD Max 3.45 mm
Barb L: 6.1 mm
Barb OD Min: 3 mm
Barb OD Max: 4.2 mm

I found this RC engine brass fitting online and a local hobby shop had them in stock. Seems like they're available world-wide.

I adapted it to M5x0.8 Rockshox thread by brazing it to 2 fittings from an old generic bleed kit. Looks a bit rough but sealed tight and my DHX2 has the best bleed I've ever been able to give it.

Cost inc delivery,
$10 AUD - 2x DUB-241
vs
$125 AUD - Fox 803-00-463 - AirNShox
$90 AUD - Anso Adapter

Float X2 Owners. Anyone do a DIY service?

Title basically. The instructions can be found here 2016-2018 FLOAT X2 Rebuild | Bike Help Center | FOX Just wondering if anyone was able to do it in their garage without the need for one off tools.
