The recalled air hoses are high-pressure scuba air hoses with a black, smooth rubber outer covering. They are about five millimeters in diameter and 32 or 36 inches long. These hoses connect the regulator to the tank pressure gauge. The phrase “Scuba Diving High Pressure hose I.D. 3/16 (4.76 mm) W.P. 5000 PSI Exceeds SAE 100RT braid with Kevlar fiber from Dupont” is printed in white lettering on the hose’s outer covering. The hoses have metal fittings on each end – one female fitting and one male fitting. “CE EN 250 230” is stamped on the female fitting and one of the following production date codes is on the male hex head fitting: T1011, T1111 or T0312.
