Would This Work As A Plunger Tube?

28.65 mm ID
33.65 mm OD
2.4 mm Wall Thickness

Those are the measurements of this tube I found while ripping apart one of those 90's water cannons (Stream Machine Hydrobolic Water Launcher) and I just happened to have my crossbow plunger tube. Lined them up, and it's a NEAR EXACT same ID.

So I was wondering if anyone with more experience in this area of modding could tell me if this would work with this skirt seal?

9562K44 might work but it's a gamble.

 

28.65mm is very close to 1.125 inches, so if that skirt seal won't work right you would probably have better luck with o-rings in dash sizes of 314 or 212.

 

I wouldn't bother using a tubing source that isn't repeatable though. If you get it to work, you can't really make a second one.

True that it wouldn't be repeatable, but I have some and its cheap. Wait... Cheap... so... yeah, the WHOLE tube is cracked in different places (I didn't notice this earlier) so ill just use the standard closed-shell tube for Crossbows. I may use it if im VERY desperate later in time, but not right now. Thanks for your help though.

Some modern stream machines have tubes that are actually sized like 1" thinwall PVC and fits 1" couplers.  It was also clear, but had a smoother finish so I'm not sure if that's the same thing.

Later I can give some more precise measurements and a better description. But right now I can't find my calipers.
