Low or high pressure flexible hose connectors are also suitable for low pressure (1.0 psig (6.9 kPa) or less) natural gas service. LP-Gas systems use either Department of Transportation (DOT) cylinders or ASME tanks and are intended to be installed in accordance with the Liquified Petroleum Gas Code, NFPA/ANSI 58. Low pressure flexible hose connectors used in natural gas systems are intended to be installed in accordance with the National Fuel Gas Code, NFPA 54/ANSI Z223.1. Pigtails and flexible hose connectors are used to make connection between parts of equipment or between equipment and service piping.
