Medical oxygen venting pipe for PRV
The venting pipe is a copper pipe - 35 cm for connection from the medical oxygen regulator - pressure relieve valve - to connect to the line for outlet to outside fresh air.
Some Flag states require a line from the high pressure regulator PRV to the line to outside fresh air, when the fixed hospital medical oxygen cylinder is located inside. The venting tube slide over the PRV. The other pipe end to be adjusted custom made to connect to the fixed line to outside.
