JT Excellerator problem with CO2 threads

[hmm]

Ive been using a JT excellerator 4.0 for about 3 months and ive never had any problems with it before. I used it last week and as soon as i put a C02 tank on it, it started leaking where the threads meet the bottom of the expansion chamber. I tried taping it and it worked for one game. The next game, i tried retaping it and even tightening the bolt, but nothing worked, it still leaks horribly. Anyone have any ideas on what to do or had a similar problem? I havent oiled my gun before, but probably should... Please help, im hoping to play in a game tomarrow...

Does the o-ring look worn? It might be time to replace it?

put teflon tape on the threads

Is teflon like electrical tape? Cuz I know we use electric tape to seal off pvc plumbing.

[thursday]

no, teflon tape isnt like electrcal tape. its not even sticky. it comes on a plastic roll and its made of like a stretchy latex type material. you just wrap it around the threads and stretch it so it like gets into the grooves, thus sealing the thread. you must have seen it before. if youve ever had an expansion chamber or bottomline put on a gun at a shop, chances are they used it.

Electric tape is not what you want to use in this application.
Teflon, tape is used on plumbing thread, I'm not a big fan of using teflon on markers, I prefer using loctite on fittings. However in this case I'd try using the teflon and see if it resolves your problem.
I'm still wondering about the o-ring?

well i don't have the answer, but i did notice last week that the threads on the inside of my ASA are chipping. i was wondering what happens when the threads wear so much that they won't hold my tank in place?

[p8ntballbadger69]

if the threads wear away so much that it wont hold ur tank ur screwed and u gotta buy a new asa but they shouldnt be wearing away thats weird

[Slenda]

well i took my gun to POLECAT last week to get a trigger job done and he said that thread wear is normal. it just seems like it would be expensive/difficult to replace the JT asa especially since they discontinued the 4.0.

[Reason]

the 5.0 and 6.0 air adapters look similar to the 4.0's...

to keep your threads lasting long and working best (aswell as your entire marker)

1. deburr all threads and parts to remove any rough edges left over from machining.

2. oil your threads to provide lubrication when screwing parts together

3. clean your threads (and entire gun internally) after every day of play, then re-oil all orings and threads after cleaning to ensure your gun will function properly with the least amount of hassle and last that much longer.

deburr? is that legal...lol i don't know what that means!

[p8ntballbadger69]

de-burr* burrs are peices of metal that stick out and are not supposed to be part of the metal kinda like slivers

[Reason]

deburring is the process of removing any rough edges on machined metal parts to smooth them out and increase the precision of parts that are assembled together. i.e.: the threads wear out faster because of rough edges left on them after the machining process, the same goes for all machined moving parts of the marker. it is important to know about manufacturing machined metal parts so you dont ruin anything by over doing it. :)

i spoke with jt yesterday, and dont worry! parts WILL STILL BE AVAILABLE for the 4.0 and 3.0. now you can all sleep better.

Better than teflon tape is teflon PASTE!!
Used normally to seal threads of gauges in car aplications. It will leak for like 1 or 2 seconds, then dry and seal forever until you move the part.
As far as JT 4.0 parts, the bottomline with regulator will cost aprox. 25.00, and the expansion chamber like 15.

Anybody got any good ways to deburr, cuz some of us aren't sure what to use.

[Reason]

for deburring use razor knives then very smooth files, maybe even some scotch brite abrasive pads on the rough areas. I just used xacto knives and very fine files tho.
