Petroleum (LPG) Industrial Hoses | Parker | LP Gas Hose Stainless Steel Reinforced | 7231 Series
Series 7231 is a large diameter, extremely durable liquefied petroleum gas (LPG)/propane transfer hose for bulk loading/unloading and vibration-resistant onboard vehicle connections. The hose meets all Underwriters Laboratories (UL21) and Canadian Gas Association (CGA Type I) requirements. The construction incorporates high tensile corrosion resistant stainless steel braided reinforcement for superior strength, durability and kink resistance. The perforated cover is resistant to mild chemicals, oil and ozone. Series 7231 is available in long lengths and factory-tested assemblies in popular configurations.
Series 7231 and DOT: LPG hose assemblies installed on on-road vehicles must meet Department of Transportation (DOT) requirements. Factory assemblies (all sizes) are pressure tested, one of the fittings is etched with a unique DOT certification number, and a document incorporating the identical certification number accompanies each assembly. Metal DOT identification bands are also available/attached for an additional charge at customer request.
Series 7231 and Natural Gas: The molecules of natural gas are small, enhancing their ability to permeate through standard rubber hose constructions. The permeation process is more rapid as the working pressure increases, and natural gas accumulates with potentially dangerous consquences. Series 7231 may be used for natural gas service, but ONLY under all the following conditions:
Series 7231 and Compressed Natural Gas (CNG): Series 7231 is not for use in any CNG application, including fuel dispensing, on-board vehicle fuel lines, or fuel transfer.
Series 7231 and Anhydrous Ammonia (NH3): Series 7231 is not for use with anhydrous ammonia.
