Can I Use PVC Pipe for Air Lines?
PVC pipe should never be used for pressurized air lines.
Never.
You might know someone who has PVC air lines in their garage or workshop but it is an accident waiting to happen. Bump it with a tool or object and it can shatter we tremendous force sending shards of sharp plastic through the room. The results can be serious injury or even death.
I’m all for saving a buck or two but this isn’t the place to cut corners. Always use steel pipe for your air lines.
These people agree:
“A section of PVC pipe being used for compressed air exploded … fragment of the pipe flew 60 feet and embedded itself in a roll of paper.” – osha. gov
