Sievert

A Sievert torch is a hand-held gas torch for soldering copper, brazing, shrinking and paint stripping, and the reason to buy into the brand is the burner tip. Sievert builds its torches around interchangeable burners, so you keep the torch you already know and change the tip for the job instead of buying a second torch. Plumbers, HVAC techs and homeowners who do their own copper work get more out of one torch that way, and in Montana that one torch earns its keep twice a year: soldering copper in the winter when a line freezes, and stripping paint in the summer when the old trim gets redone.

Sievert AB is the Swedish maker that has built professional heating tools since 1882, starting with the first blowtorch, and Rothenberger has owned it since 2003. Its products are developed in Sweden and produced in Europe, and it builds them around one idea: a craftsman’s safety comes first.

Pick the tip by the job

Two flame shapes cover most of the torch work around a house or a service call.

The standard tip throws a round, focused flame, and it’s the one for soft-soldering a copper fitting, sweating a valve or heating a small part. The PowerJet standard burner is rated 1.2 kW, made for general heating, and it goes on and off the PowerJet torch with Sievert’s Twist ‘N’ Lock connection: the burner twists and locks into place instead of screwing on, so changing tips takes a turn of the wrist instead of a wrench and a search for the wrench. That focused 1.2 kW is the right amount of heat for house copper. When a January cold snap splits a half-inch line in the crawl space of an older Missoula or Kalispell house, this is the tip that puts a new coupling on it: the heat goes into the fitting and not across the floor joists behind it, which matters when you are on your back in a crawl space with six inches of clearance and no way to move fast.

The flat flame tip spreads the heat across a wide strip instead of a point, and Sievert builds its flat flame burners for paint stripping and preheating. Use it on old paint on trim, a door or a window sash, or anywhere you want even heat over a bigger area. The MultiTorch Brass flat flame tip twists into the MultiTorch Brass torch. Montana towns are full of houses from the 1910s through the 1950s with eight or ten coats of paint on the window trim, and a flat flame is the tool that lifts that in sheets where a sander clogs and a chemical stripper takes three rounds. Keep the flame moving and scrape as soon as the paint blisters, because heat parked in one spot scorches the wood. Paint on a house built before 1978 can contain lead, so test it before you heat it.

Match the tip to the torch

Sievert tips are made for a torch, not for every torch. The PowerJet standard tip fits the PowerJet, and the MultiTorch Brass flat flame tip fits the MultiTorch Brass. Look at the name on the torch handle before you buy a tip, and the tip goes on right the first time.

Shut the gas off and let a tip cool before you twist it off, and seat the new one snug so the joint can’t leak.

Beyond the hand torches, Sievert builds hose-fed torch systems such as the Promatic and Pro Venturix that roofing crews run off a propane cylinder for torch-down membrane, shrinking and de-icing.

Why Sievert

One torch, the right tip for the job, and a tip change that takes a twist. Sievert has built heating tools in Sweden since 1882, its burners put the heat where the work is, and the Twist ‘N’ Lock system means the torch you already own keeps up with the next job instead of getting replaced by it. That is the reason to buy the tip instead of another torch.

Frequently Asked Questions

Which Sievert tip is best for soldering copper pipe?

The standard burner tip. Its focused flame heats the fitting quickly without spreading heat onto the wall behind it. Heat the fitting, not the solder, and touch the solder to the far side of the joint; when the fitting is hot enough, the solder is drawn into the joint on its own.

What is a flat flame torch tip used for?

Jobs that need even heat over a wide strip instead of a point: stripping paint, preheating and warming a large surface evenly. It’s the wrong tip for soldering, because the heat spreads out instead of going into the fitting.

Will a Sievert tip fit my torch?

Only if it’s made for that torch. The PowerJet tips fit the PowerJet, and the MultiTorch Brass tips fit the MultiTorch Brass. Match the tip to the torch name on the handle before you buy.

What Sievert torch tips are there?

Two cover most work: the standard burner, a round focused flame for soldering and general heating, and the flat flame burner, a wide flame for stripping paint and preheating. Sievert makes a range of others for its hose-fed systems, but the standard and flat flame tips are the ones that fit the hand torches on this page.
