Sievert 334401 Bruciatore per brasatura dolce per manici Pro 86/88

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.

Why choose it

The brush flame delivers a broad, soft heat pattern that reduces the risk of overheating sensitive areas while soldering. Brass construction provides durability and resistance to corrosion from flux and heat. The 22 mm diameter is matched to common soldering applications, and the burner's 2.0 kW output is sufficient for plumbing and light heating tasks.
