How hard is it to change a bottle valve?
How hard is it to change a bottle valve? I've got a 15# NX bottle that has no provision for a pressure gauge. This drives me nuts, because I have to charge the whole line to see my pressure. I see some replacement valves with siphon tubes on the market that have provisions for 1-2 points for gauges or accessories.
Now I understand that when on right, they hold back 1000+psi and are pressure rated for probably twice that while leak checking perfectly.
So....how hard is it to take off a valve, and install a different one? What do you use to hold the bottle stationary without scratching the hell out of it?
And what's a good quality gauge for bottles? I only ask because I had not one but TWO NOS brand liquid filled gauges fail and leak that liquid all over my tank 2x in the first 6 weeks I owned that kit.

Hey you can. I just put a longer bottle nut on it like the bronze on that goes on a nx bottle. put a thick rag on it and then take a hammer and hit that nut extention sideways and it knocks it loose. All they do is screw into the bottle.
I have changed valves to several nitrous bottles. It's easy.
You need a place to hold the bottle, (like a pipe chain bench) and a BIG crescent wrench, plus sealant and somebody to help you.
Make sure all pressure is relieved and wear safety googles before you procceed.
I always test with 2 pounds of N2O and heat it with the bottle heater, then put it under water to check for leaks. If no leaks are found, you can fill it full.

- Put a rag around the bottle and clamp it with the bench, the firmer the better.
- Unscrew valve with the wrench.
- Clean bottle's interior with compressed air
- Screw the new valve by hand to check proper fitment and siphon alignment
- If ok, remove it and apply loctite or any thread sealant (don't use teflon tape).
- Screw the valve and fasten it with the big wrench. Tighten it as strong as you can.
- Install pressure gauge

Hold the bottle between your legs. Put a big cresent on the base of the valve and give the end of the wrench a few swift hits (I use my hand). The valves seal with a o-ring so they aren't usually super tight and no sealant required.
I was gonna call today and order one but I'm still waiting on a large credit return. I'll have it ordered by the end of the week. Thanks though, if I have any questions, I'll definately shoot ya a PM.
