View Full Version : What's The Problem Here!?! Tac One Issues...

Ok, so I have an update on my leaky Tac One. Here's what I've done:


1. Fully inspected, cleaned, and oiled my ULT On/Off.

2. Put two drops of oil into my macroline fitting attached to the valve

3. Aired up the marker via macroline to another fitting on a CP On/Off ASA. I'm using a Ninja Paintball 48c.i./4,500p.s.i. tank filled to around 4,000p.s.i.

Here's what happened:

1. The marker has a slight leak, the best way to describe the area where it's leaking is somewhere directly above the field strip screw. That's just the general area where it is.

2. I pulled the trigger, the marker fires but the leak gets a little bigger for a while. Eventually if I hold the trigger back a while the leak slows down and becomes less noticeable but it's still there.

3. Letting go of the trigger brings me to the slight leak described in #1.

I repeated that around 6 or 7 times just to confirm that it's consistent. Please note, my Level 10 isn't tuned at all (the parts are on the way) and the ULT was used when I bought it and I never fired the marker with the ULE so I don't know if it fired when I bought it. I'm just checking to see what you guys think the problem is.

From what I understand it has to be an o-ring in the on/off correct? The on/off should be sealing both before and after firing, meaning if there was a problem it would leak both before and after firing. Correct? I don't think it's a regulator, bolt or powertube issue because of the area of the leak but I could be wrong.

Replace the large oring on the outside of the on/off(on/off bottom)

Do you still have the original on/off? If so, swap the on/offs and see if that makes a difference... and if there is, then you know that the ULT needs a new o-ring somewhere.

However, the area of the leak you are describing makes me wonder if the Regulator Body O-Ring (the big, fat o-ring that seals the two halves of the Valve Body together) might be the culprit. I assume you have a parts kit with an extra reg body oring. Try swapping that out as well to see if that helps.

My parts kit is on the way, and thank you TunaMan for the info. Is there anything else I should try?
