1811321 Genuine Bromic Oxygen Cylinder 1.4 Litre, Replacement Oxygen Bottle for Portable Oxy Brazing Kits

Bromic part 1811321 is a 1.4 litre oxygen cylinder for portable oxy-fuel brazing kits, the kind refrigeration and air conditioning technicians carry from job to job. It supplies the oxygen side of the torch, which is mixed with a fuel gas to produce a much hotter flame than fuel gas on its own. Check that the cylinder size and connection suit your regulator and kit before ordering.

Oxygen for portable brazing kits

Brazing copper pipe on refrigeration and air conditioning systems needs a hot, concentrated flame. Portable oxy kits get there by mixing oxygen from a small cylinder with a fuel gas at the torch. Small cylinders are light enough to carry onto roofs and into ceiling spaces, but they empty quickly on bigger joints. Running low on oxygen shows as a flame that goes soft and yellow, struggles to bring the joint up to temperature and leaves the brazing rod flowing poorly. A spare cylinder avoids stopping mid-job.

Handling oxygen cylinders safely

Keep oil and grease away from oxygen fittings, regulators and your hands, as they can ignite in pure oxygen. Make sure the regulator suits this cylinder before connecting it, and never force a fitting. Leak test with soapy water, never a flame. Store and transport cylinders upright, secured and in a ventilated space, away from heat.
