Filling Nitrous Bottles??

[TheBreeze]

I am looking for a cheaper alternative to the 20 lb. boondocker nitrous refill stations. I see there are 20 lb nitrous bottles available. Could one of these be used to transfer nitrous into 3 lb. bottles just like the refill station if set up with the proper fittings? Just get the 20 lb bottle warm, and freeze the 3 lb bottle, crack the valves and filler' up?

Here's what i did. i went and got a large bulk bottle from the local welding supply store ,Probably 4/5 feet tall(60 pounds?) And had a hose made with a ball valve on it. Had the bottle upside down in the shop. i filled all my 3 pound bottles this way with no problem's You can put to much in a bottle when you feeeze it so do not over do it.In fact i may still have that hose set up here.Though i do not use nos any more.

I have looked into that, but I need something more portable for trips out west.

just put the big bottle in the hotel room when u get there so it has time to warm up when your out rideing the first day noone ever questions what your doing​

on weekend trips just buy a 20lb bottle and fill the 3lb bottles off it. Or take more 3 lb bottles. If your like me tho I can easily go through 9lbs of juice in one day

Exactly as you said, just keep the transfer line as short as possible and leave the transfer line fitting a little loose at the 3lb bottle end, purge the air out and tighten it as soon as you see the N20 escape.

We use to have to fill a lot of 10lbs bottles with the 63pounders when we were running N20 on Cigarette Boat w/Twin Big Blocks.

Can never get enough of that Nitrous once you get used to it.

I just filled mine up tonight this same way. Buy a small scale to make sure you're not overfilling.

My Refill Station

This is where I refill mine on my back entrance way, big bottle needs to be warm, freeze small bottle, perg air out of line before filling and donnot over fill, I found out the hardway when my pop valve blew going the trail, when the NOS hit my SLP pipe it weakened it so when I rode next time it blew a huge hole in the bottom of the exhaust, expensive ride, MADDOGWFO

I've seen nitrous bottles pop off in the middle of the night while sitting in a warm hotel room. You don't need an alarm clock at this point....

chilling the little bottle can sometimes over fill the little bottle causing it to blow off the safety. I Dont like to chill them
Here is a cheap place for parts.

I've never had an issue with over filling, usually I have to fill my 3lb bottle 2x to get it full (fill until it quits transferring then put the little bottle back in the freezer until it is cold and fill it again).

Anyway, main reason for posting here is to remind you to wear gloves when you work with N20, I've burned myself several times.

I've been filling Nitrous bottles since 1980, never heard of over-filling.

We always put the receiving bottle in the freezer, could never get a full fill with a warm bottle, as we checked them on a scale while filling.

 

[TheBreeze]

As long as I stay under the max bottle weight on the scale I would be ok right?

 

[Perk]

thats right.

NOS makes a transfer filter that fits inline in the fill hose,get one and use it every transfer. Make sure to empty the receiving bottle before refilling. Pay attention to the tare and full weights of the receiving bottle-I used to hang the receiving bottle on a digital fish scale after filling. If you go over the full weight and heat up the bottle, the plug will blow.
