Airgas Y15-4PFLX72FF Oxygen Pigtail Hose 316 Stainless Steel 1/4 Inch FNPT

Airgas Y15-4PFLX72FF Oxygen Pigtail Hose is a 72-inch, all-stainless-steel flexible hose designed for high-purity oxygen transfer. It features 316L stainless steel construction with 316L core components and 321 stainless steel braided armor, and it terminates in 1/4" FNPT connections on both ends (1/4" FNPT x 1/4" FNPT). This oxygen-compatible pigtail is built to withstand demanding gas-transfer tasks while resisting corrosion and wear in high-pressure environments. It is rated for a maximum inlet pressure of 3,000 psig, with a proof pressure of 4,800 psig and a burst pressure of 13,000 psig, illustrating its suitability for robust laboratory, industrial, and welding/brazing setups where a reliable flexible connection is needed. The 72-inch length provides practical routing between regulators, manifolds, and equipment without excessive slack or tension, while the all-metallic stainless-steel construction helps minimize contamination and compatibility concerns in oxygen service. Ideal for linking oxygen sources to regulators or distribution manifolds in research labs, manufacturing lines, and maintenance environments that demand durable, high-pressure oxygen transfer hose assemblies.
