Thread: recharging a flat WD40 aerosol cans

Are not the wd40/ crc and the like filled with propane/ butane or the like

These gases are pressure temperature related substance...liquid/vapour ....the higher the liquid temp the higher the pressure...so do not over pressurise and all will be safe
a pressure temp chart will reveal all

They can leak if tipped over but I made a stand to keep them upright in the back of the car.

I have a very similar experience except that it is with CRC. My original spray bottle (with push button, not trigger as the newer ones seem to be) has been going since the mid 1970s I would think, and except for a slightly too weak a return spring which sometimes doesn't push the button back for the next pump cycle, still works fine without leaks. I bought another hand spray bottle, again CRC brand recently and have not yet filled it, but it cost $10 at a field day, because I have had no luck with kitchen spray bottles with workshop solvents other than Metho, which they seem to handle OK

WD40 and some CRC products appear to use CO₂ as the propellant.

same same different stuff

5+5=10.jpg Playing around with spray cans - no thanks - I'm tight when it comes to money - but not that tight.

There was a can available brand new that all you did was pour in your fluid and and pump them up with an air chuck. I saw them for sale in the 80.s

If I recall they were very expensive.

You're right Grahame, Can't remember what it cost me - being tight with money couldn't have cost much - I brought one when I tried me hand at fishing lure making and painting - I couldn't afford a compressor back then so walked to local servo not far from home to pump darn thing up all the time - I got more exercise than it did as a spray painting unit - it was about as useless as ......... on a bull.

Wurth do a nice line of pump bottles https://www.google.com.au/search?q=w...w&ved=0CF0QsAQ

I have owned a Wurth pump bottle for over 12 years now and it still doesn't lose any air.

Wolfchester also do an identical one, I think with Forch branding (can't be bothered going out to the workshop)

We had 2 or 3 at my old work that had been used as spray bottles for petrol for the same amount of time. One was starting to occasionally dribble out the nozzle by itself after that length of time, but was otherwise still working fine. Probably more from the years of being knocked off benches and hoist legs onto the concrete than anything else. Got a seal kit, threw it in, good as new. Personally I've got a Forch one that has been used only to spray petrol for the 3-4 years I've had it, and its still perfect, holds pressure for weeks.

Turps shouldn't be an issue for them at all - they're sold for use with brake cleaner, which I'd imagine is far more corrosive than turps. Expensive, yes. But you won't buy another one - unless you want to have a second type of fluid ready to go.....
