PVC in cold

[maxfreke88]

I left my air cannon in 30F weather for 1 day, i heard that this makes pvc brittle will it thaw out to it original state or trash it ? i usually fill it to ~80psi is it safe to fill it to that and, when (if it thaws) do i fill it??

THANK YOU

It should be fine if you warm it slowly for quite a while.
Although I'm unsure about the long lasting effects of cold weather on PVC, isn't 30F way below freezing?

only 2 degrees below freezing, i think if you let it come to room temperature slowly it will be fine, just don't shoot it when it's still cold, and if you must shoot in the winter, pump it up inside, then go outside to shoot, then go back inside to pump again

30F is 2 degrees below freezing point. Just wait about a day for it to waarm up by keeping it inside your house, which is hopefully warmer than 30F

thanks for the fast response!! Actually it is about freezing temp or -1C

[maxfreke88]

is 80 psi a good pressure for tommorow

As long as it's had a good warm up.

I have no idea about Farenheit, I'm a Celcius man.

To convert from Fahrenheit to Celsius you subtract 32 then multiply by 5/9. From Celsius to Fahrenheit you multiply by 9/5 then add 32. The PVC should be fine like everyone else says.

Do not drop it when cold.
I dropped one from 7' at 45 f. on concrete and two fittings shattered, I mean tiny pieces.
I was amazed, thought PVC was tougher than that.

below 50F pvc loses it properties of storing gases

thanks! anyone know if i can modify this valve

for use with the cannon

Yes it is possible but your are going to have to see if it has a guide rod or a flow control (which you want to take out).

Also you are going to have to fill that hole with epoxy, (next to the solenoid, has a screw cap on it i think)

what does taking the guide rod out achieve? Just wondering im a noob to pneumatics

Better flow
