Oxygen Tank and Low Flow Regulator

Choose from a 540 or 870 regulator option: the 870 does not require a wrench to mount while the 540 does. 540 tanks are available in 255 and 640 Liters. The 870 is available in 255 Liters.

540 Oxygen Tanks are colorless and temp coated. This will make it easier for you to get the tank filled. Temp Coat or Temp Alert is designed to change the tank's color if it exposed to heat over 350 degrees F (176 degrees C).

The tank will turn a purple color indicating the tank has been compromised and must be condemned. This is a safety feature. Aluminum oxygen tanks that exceed these temperatures may develop issues that make filling unsafe.

The high pressure cylinder oxygen is regulated to 50 psig (345 kPa) before passing through the flow control valve and barbed outlet fitting. To ensure safe operation, each regulator is equipped with an internal safety relief valve.

The unique design of the Companion 360 enables the flow control valve to be rotated 360 degrees for optimal positioning when setting flows or connecting oxygen tubing.
