O2 - E Wrench
E-Tank Wrench is a small tool used to open and close the valve on E-size oxygen cylinders. Because oxygen cylinders must be properly opened to deliver flow and securely closed when not in use or during transport, the wrench is an essential safety accessory for any portable cylinder setup.
OxyCare includes an E-tank wrench with all portable cylinder oxygen setups and supplies replacement wrenches as needed.
