Fire Extinguisher tyre pump?

[Shebeen]

Your funeral:

 

who needs anymore evidence?!!

 

I watched this about 5 times...before even the slomo was on!

wonder if they ever found his cap.

 

 

dude#2 got out of way in time...thing landed just where he was.

That looks proper.

Still want to put the regulator in.

Also want to have the system pressure tested by a company which does all our dive cylinders.

[Eddy Gordo]

Yeah regulator and gauge for sure

[Skylark]

Yoh all the videos and naysayers have got me rattled.

 

But if a extinguisher can is rated for the pressure and you virtually never hear of extinguishers randomly exploding or exploding at all(and they are typically hung on walls at eye level and in heavy traffic areas including high liability public locations like shopping malls, why aren't risk assessors banning them?) and further to that as a tyre inflator will be pumped to well below their rated pressure what really is the risk?

 

Do people gingerly approach their Adenhoff/Makro etc cheapie chinese air compressors in fear they may rupture at any moment, never heard of household air compressor being high risk devices prone to exploding?

Those heavy duty tire generally have a metal bead (separate) which is used to hold the tire rim in place,  If not fitted correctly, the tire can pop of.  The metal bead ring can be seen in the pic lying by itself.

No man, there is no issue with Extinguisher tanks, gas tanks, or dive tanks.

[Boerklong]

I've seen one of those rings jump off. Not a pleasant feeling. There is a reason those things are supposed to be pumped in a cage

No the compressors are fine - never heard of issues with them.

 

You can use a scuba cylinder as well - will last for eons as they are at 220 bar. Just need a regulator and a tire adapter that plugs in to the power inflator as that has enough air volume through it.

 

Plenty old scuba cylinders and regulators at cash converters.

 

Small compressors run fine as well..

But you are one of the prime naysayers putting the fear of the devil into all and sundry?

 

Granted I agree using a 2L coke bottle or any container not designed to be pumped to high pressure is taking a rather foolish chance but extinguisher bottles would appear for all intents and purposes to be ideal, safe and cheap.

 

Granted there's going to be some dim wit who has an industrial air compressor at work(or petrol station compressor with a faulty regulator) and decides he wants to try fill it "properly fill" and doesn't watch the air pressures involved and then when the extinguisher blows up its shrapnel everywhere.

 

I think the point is not the bottle itself but filling containers with compressed gases is not childs play, you need to know what you are doing and know the limits of what you are working with. You don't want to be the kid at the shell garage who pumps his BMX tyre without concentrating and then it pops with a very loud bang, if you do that with a metal container or even some kind of plastic container there'll be no laughing involved.

Not adding much to the topic but a double layer of rim tape can pick up the slack enough for a footpump to work. Just throwing it out there, ymmv.

Hi,

 

Sorry - didn't mean to do that. I know minimal amounts about fire extinguishers. But i have some experience with compressors and pressure vessels in terms of using them.

 

Just remember pressure vessels are purpose built as well. So if they are pressure tested then you will be okay. Some are even single fill bottles - you may therefore find they are not engineered for refills. Just saying.

 

Scuba tanks I know, compressors I know. Fire extinguishers - no idea (never used them) and coke bottles - stand well away this is going to get ugly...

So finally made mine and super chuffed

 

Just removed the safety release drilled the whole and popped the valve through.Put plumbing tape on every thread , skrewed back together and volla

 

Pumped to 90psi no leaks and seated my 2.4 Ibex tire with both sides pulled off the bead, Its was so hard I had to let some air out.   I have much more peace of mind using this than my old 2l bottle.

 

NOTE: I will only be using me to seat tires , not to transport around while pressurized as a back up.   ( 1Kg powder extinguisher)

[Eddy Gordo]

Well done. If you wanna transport it in your car, then get a bracket
