NFPA 58 2020 Edition section 7.2.2.7: Prior to filling a cylinder, the face seal on CGA 791 and 793 connections shall be visually inspected for defects (e.g., cracking, gouging, tearing, roping, etc.). If a defect on the face seal is found, the cylinder MUST NOT be filled.
What it meansIf you are filling a propane cylinder with either of these valves, the face seal needs to be inspected prior to filling.
Why it changed
If you dispense propane into a cylinder with a damaged face seal, you may experience connection leaks, property damage, or personal injury. A cylinder with a damaged face seal is also a potential source of leakage to a customer that connects it to an appliance.
