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.

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

Let the sealant cure at least a day and its ready to be filled.
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.

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.

Another good useful item is one of those rubber pads that hold carpets onto hardwood floors...wrap that around the bottle to hold it firmly and prevent it from spinning.

I've used those before. They work like a charm.
