Sievert 334401 Soft Soldering Burner for Pro 86/88 Handles

Plumbers and HVAC technicians using Sievert Pro 86 or Pro 88 handles can swap in this 334401 soft soldering burner for precise, controlled heating. Its 22 mm brass head produces a brush flame that spreads heat evenly over copper pipes and fittings, making it suitable for soldering joints up to 2 kW output. The burner threads directly onto the handle and runs on propane, butane, or mixed gas at a recommended working pressure of 2 bar.
