New 1/4 Braided Stainless Air Hose 42 Cylinder Connector

brand new 42" long overall length stainless steel braided hose, 1/4", female brass swivel flare fittings on both ends. hose is a plastic - think it is the ptfe type as it's a somewhat flexible bluish plastic looking hose. these are mcmaster items but sorry have no clue on the part #. they would be superb for hooking up air cylinders as i'm sure they are rated for at least 500 psi. think the fittings are the 37 degree flare type.
