Is JFC Retail safe to use on natural gas and liquid petroleum gas lines?
A. NO! You should not use JFC (JFC), or solder or any other bonding material that melts at a lower temperature than copper, on any natural gas or LPG lines. JFC (JFC) will bond the copper and is compatible with natural gas and LPG; however, JFC (JFC) will un-bond at approximately 400 degrees F and would allow gas to feed the fire. This is also true with any solder. Gas lines should be constructed according to local, state, and federal Guidelines. Copper melts at 1984 degrees F (1085 degrees C).
