SIEVERT

Sievert is a Swedish brand with a history dating to the early 20th century, known for portable gas heating and soldering equipment. The product line includes propane torches, soldering irons, brazing and heating kits, and the hose assemblies that connect torches to fuel cylinders. Sievert equipment is used in plumbing, HVAC, roofing, metalworking, and general maintenance where a directed flame or heat source is required. The brand's core technical focus is on controlled fuel delivery and durable torch construction. Hose assemblies are a critical part of that system: they must handle liquid propane at working pressures typical of portable cylinders, resist abrasion and weather exposure, and maintain a secure connection between the fuel source and the torch. The Sievert hose assemblies supplied by 3G Electric are built with a 1/4 in inside diameter and black covers, and are fitted with FLH x FLH (female flare) connections on both ends. These hoses are intended for liquid propane heating, soldering, brazing, and gas-cutting applications. Available lengths include 4 ft, 10 ft, 12 ft, 25 ft, 30 ft, and 33 ft, covering short bench work, service calls, and longer runs where the cylinder must remain outside a work area. The FLH fittings are a common interface for propane torches and regulators, allowing direct connection without adapters in many setups. The black cover material is typical for propane hose in this class, offering resistance to oils, grease, and outdoor conditions. 3G Electric supplies Sievert hose assemblies as part of its broader industrial equipment catalog. The company serves plant engineers, maintenance managers, and procurement specialists who need to specify or replace gas hose for heating and soldering operations. Because these hoses are a wear item, correct length and fitting type matter for both safety and workflow. 3G Electric provides the part numbers, dimensions, and connection details needed to match a replacement hose to an existing torch or regulator setup. The catalog includes multiple lengths of the same 1/4 in ID hose, so a single specification can be scaled across different workstations or job requirements. For buyers standardizing on Sievert torches and accessories, these hose assemblies are a direct-fit component rather than a generic substitute. The product data supplied by 3G Electric includes manufacturer part numbers such as 1530IS, 3015-04, 1533IS, 1512IS, 1510IS, 1525IS, and 1504IS, which can be cross-referenced against existing equipment documentation. This supports maintenance planning and spare-parts inventory without requiring a change to the torch or regulator interface. In summary, Sievert hose assemblies are a focused product family within the broader Sievert gas heating and soldering range. They are specified by inside diameter, length, cover color, and fitting type, and are used wherever liquid propane must be delivered to a torch for heating, soldering, brazing, or cutting. 3G Electric supplies these hoses globally as part of its industrial equipment distribution, with the technical detail needed for correct selection and replacement.

Frequently asked questions

Common questions about SIEVERT from 3G Electric.

What is the difference between the Sievert 1504IS and 3015-04 hose assemblies?

Both are 4 ft liquid propane hose assemblies with a 1/4 in inside diameter, black cover, and FLH x FLH fittings. The 1504IS and 3015-04 are separate manufacturer part numbers for hoses in the same length and connection class. When ordering, confirm the part number against your existing torch or regulator documentation. The functional specification — 4 ft length, 1/4 in ID, FLH x FLH — is the same, so either can serve the same connection role where that length is required.

What does FLH x FLH mean on a Sievert propane hose?

FLH stands for female flare. A hose listed as FLH x FLH has a female flare fitting on both ends. This is a common connection type for propane torches and regulators, where the mating part has a male flare fitting. The flare interface creates a metal-to-metal seal when tightened, which is typical for fuel gas connections in this class. Confirm the thread size and flare angle of your torch and regulator before ordering, since FLH fittings are specified by both thread and flare dimensions.

What lengths are available in the Sievert liquid propane hose assembly range?

The Sievert hose assemblies supplied by 3G Electric include 4 ft, 10 ft, 12 ft, 25 ft, 30 ft, and 33 ft lengths. All share a 1/4 in inside diameter, black cover, and FLH x FLH fittings. The 4 ft versions are suited to bench or close work. The 10 ft and 12 ft lengths cover general service work. The 25 ft, 30 ft, and 33 ft lengths allow the propane cylinder to remain outside a work area or at a distance from the torch. Select length based on where the cylinder will be positioned relative to the work.

Can Sievert hose assemblies be used for gas cutting as well as heating and soldering?

Yes. The Sievert hose assemblies in this range are specified for liquid propane heating, soldering, brazing, and gas-cutting applications. The 1/4 in inside diameter and FLH x FLH fittings are consistent across the lengths listed. Gas cutting with propane requires a suitable torch and oxygen supply, but the fuel hose itself is rated for the application category. Confirm that your torch and regulator are compatible with the hose fittings and that the working pressure of your setup is within the hose's intended service range.

How do I choose between the 25 ft, 30 ft, and 33 ft Sievert hose assemblies?

The difference is length: 25 ft (1525IS), 30 ft (1530IS), and 33 ft (1533IS). All have a 1/4 in inside diameter, black cover, and FLH x FLH fittings. Choose based on the distance from the propane cylinder to the torch and the routing path. Longer hoses allow the cylinder to be placed further from the work, which may be required by site rules or by the need to keep the cylinder upright and outside a confined area. Account for routing around obstacles when estimating required length.

What is the inside diameter of Sievert liquid propane hose assemblies?

The Sievert hose assemblies listed by 3G Electric have a 1/4 in inside diameter. This is consistent across the 4 ft, 10 ft, 12 ft, 25 ft, 30 ft, and 33 ft lengths. The inside diameter affects flow capacity and pressure drop over the length of the hose. For the torch sizes typically used with these hoses, 1/4 in ID is a standard size. If your application requires a different flow rate or a longer run, confirm that the pressure at the torch remains adequate for the intended heating, soldering, brazing, or cutting task.
