Homework Answers
It means
CGA= Compressed Gas association
has classified this oxygen cylinder as
number 540
0.903= the thread bore is of 0.903 inches
14= It has 14 threads per inch.
RH= The connection is right-handed (RH) and should be turned clock-wise to tighten.
Ext= The threading is external (E).Hence the connections of the cylinder and the attached equipment should be fixed together using a nipple, which is denoted by NGO. A nipple is actually a type of bolt which fits together two male connections.
