To all, both the Flex Head and the Victaulic brand are UL listed and FM approved for installation in fire sprinkler systems. Thus as long as you are installing per the manufacturers instructions then you are good. NFPA 13 section 9.2.3.3.1 Says " shall be installed in accordance with their listing" so if you have followed the listing for the brand you are using then you are in accordance with NFPA 13 and there should be no further requirements.
