CO2 regulator connection

[blue33]

Do you guys connect the CO2 regulator using those white tape first before connect to the CO2 tank or just direct connect to the CO2?

[Aquaculture]

I'm quite kiasu to using white tape so as to ensure no leakage of water or gas.... even the little hole that connects the black tube to the reactor. I white tape whatever I can as its cheap anyway.

hihi, blue
i seconded Aquaculture method.
me too is a kaisu type i white tape all the joint and even at the internal reactor i use cable tie to secure it.

[blue33]

Oh Gosh... I just direct connect it. Time to do some work on it. Thanks guy.

If it is metal to metal (hard surface to hard surface) then I will use the white tape. It will help to prevent leak as well as metal ware off due to friction. Also always use soap bubble to check for leakage.

[blue33]

I dont use white tap cause JBJ regulator inside there's rubber seal inside, and one way to test the leaking is, release the CO2 and close it again and take down the reading from the gauge, leave it for 1 day, if the reading drops it show there's a leak. This was teached by Chan from NA, it works for me.

[Shadow]

Thats another way, but I can't wait for one day (no spare tank) soap bubble still the best method.

If you white tape, make sure it is properly done and does not get introduced into the regulator. My regulator comes with those plastic seals which are tougher and works well for me (no white tape needed.).

same. Tape gets in the way on the ridges, will cause minor problems. Just remember to buy the plastic seal again everytime you send your cylinder for top up. But then dont spend time cracking your head too much on this, Im running on a 5L co2, and i dont see myself topping up for another 2years...

Haha... he told me this too.... my neighbour jbj brass bubble counter the plastic container burst for no reason

[tawauboy]

the bubble counter burst for 2 possible reasons;
a) overpressure - faulty regulator
b) cracked container

it is advisable to get the regulator checked.

Folks, do you remove the JBJ regulator when bringing the tank for refill ? Or your bring the entire tank+regulator along and refill through another side inlet in the open\close head?

Thks.

[Aquaculture]

Just the canister.

[unclerobin]

not to damage the regulator during transportation, i remove it to do the exchange.

Folks, I was told not to turn the main regulator by a little. Rather turn it on fully to avoid damaging the regulator (the one connected to the tank). is it true ? Any other advice ?

Thks.

Thanks guys.

nope. 1/4 to 1/2 turn works fine.

[Shadow]

I though the other way around? turn it full might damage the needle valve due to pressure. but I'm not too sure my self

[tawauboy]

if there is no proper regulator, then the needle valve will be damaged. the cylinder pressure is 1000+ psi while the needle valve is usually rated to 10 bar or 145 psi.

however, if you have a proper regulator then there is no difference. the regulator is rated to operate from a co2 cylinder.

Folks, thanks.

I'm new to using compressed co2. My fren gave me a 2 litre tank with JBJ regulator with solenoid.

1. Why do I get the high quality check valve ? Read from web that the metal one is better than the common plastic valve.

2. Is it normal that the bubble rate is irregular ? It seeems to be faster when the solenoid as first turned on and go slower after that.

Thanks all.
