1811322 Genuine Bromic Oxygen Gas Cylinder 2.2 Litre for Portable Oxy Brazing Kits, Refrigeration and Air Con Copper Work

This 2.2 litre oxygen cylinder from Bromic, part 1811322, is the oxygen supply for portable oxy brazing setups. Paired with a fuel gas, oxygen lifts the flame temperature high enough for brazing copper pipework, which is everyday work for refrigeration and air conditioning techs. Check that the cylinder's valve suits your regulator before ordering.

Running out of oxygen mid-braze

A brazed joint needs the copper heated evenly to the point where the filler rod flows into the joint, and a fuel gas on its own often struggles to get larger pipe hot enough quickly. Adding oxygen produces a hotter, more focused flame. When the oxygen runs low, the flame softens, heating slows and joints can end up incomplete or porous, which is a common cause of slow refrigerant leaks. Keeping a spare cylinder in the van means you're not stuck halfway through a job.

Handling and storing oxygen safely

Keep oil and grease well away from the cylinder valve, regulator and fittings, as oxygen under pressure can make them ignite. Store and transport the cylinder upright and secured, in a ventilated space away from heat and fuel gases. Open the valve slowly, check connections with leak detection fluid, and close the valve when you've finished.

Questions about this part

What fuel gas is this used with?

Portable oxy kits commonly pair oxygen with LPG, MAPP style gas or acetylene, depending on the torch. Use the fuel gas and regulator your torch is designed for, and never swap fittings between gas types.
