527BA Series Breathing Air Refill Hose | Parker Parflex

Parker Parflex 527BA hose is specifically designed for breathing air tank refill applications. Do not use in SCUBA systems - this hose is not for use between a pressure reducing regulator and breathing mask.

For fitting attachment lubricate only with water or non-toxic lubricant. Do not assemble with petroleum or hydrocarbon based lubricants. Do not flush with solvents of any kind. This hose does not contain a conductive element; therefore, it should not be used with explosive gases such as pure oxygen and hydrogen.

527BA hose is compliant with CGA Grade E Breathing Air Standards but please be aware that air quality is dependent upon all system components.
