Displacement oiler

This hot steam oil for model building is ideal for the operation of real steam models. The hot steam oil is very viscous and also adheres very well to hot components. When a model steam generator is operated with steam, normal oil (for example, fine mechanics oil) is washed out very quickly by the steam. Since the hot steam cylinder adheres very well, it remains in the cylinder, the piston and the piston rod for a long time. You can also use the hot steam oil in our displacement oil. Due to its viscous nature, the hot steam oil is not suitable for lubricating Stirling engines or flame eaters.

This safety valve is made of brass. It is significantly smaller than the weight safety valve. This makes it suitable for smaller boilers or steam systems. The safety valve is loaded with a stainless ball and spring. The screw-in thread of the pressure relief valve is M6x0.75. Our soldering sockets are best suited, which are soldered into the boiler in order to subsequently screw in the safety valve. Under no circumstances should a steam boiler be operated without a safety valve. The safety valve prevents the maximum pressure from being exceeded. The safety valve is set to 4bar, but can be adjusted.  Dimensions of safety valve:  Height with thread: 37mm  Height without thread: 31mm  Wrench size: 10 mm The matching Solder sleeve M6x0.75 can be found here.

The soft copper tube is suitable for all applications in steam model making and for technical model making. The Cu pipe is also suitable for gasoline lines or diesel lines for motorcycles, tractors and vintage cars. The copper tube is very malleable and can be easily bent into narrow radii by hand. Our soft copper pipes are delivered in a ring and are 1000mm long. If you need a 3m long copper pipe in one piece, simply order 3m copper pipe in the desired diameter. In order to keep your waste as low as possible, we always deliver the pipes in one piece in the length you ordered. Matching compression fittings can also be found in our shop. If you order several meters of a CU pipe diameter, we will always send you the copper pipe in one piece. The following CU tubes and copper tubes in a ring are available: 3mm x 0.5mm soft copper tube 4mm x 0.5mm soft copper tube 5mm x 0.5mm soft copper tube 6mm x 0.5mm soft copper tube 6mm x 1.0mm soft copper tube 8mm x 1.0mm soft copper tube 10mm x 1.0mm soft copper tube

We have silver braided bars with a silver content of 55% (L-Ag55) with a length of 500mm. Because of the relatively low melting point of this silver braze, the model builder in the field of technical model building is almost exclusively concerned. The working temperature of this hard solder is 630 ° C. The silver as an alloying component in the solder does not only reduce the working temperature, but also improves the flow properties. Furthermore, silver has the positive property of combining well with other metals. For brazing brass and steel, silver solder flux is essential. The low working temperature of the silver solder bars allows the thermal load to be as low as possible for the processed material. It is important not to heat the workpieces too much, especially in the case of brass. In combination with our silver solder flux you achieve with these silver solder always optimal results. The silver braided bars can be purchased from us in the shop in 2 different diameters. For fine soldering as it often happens in technical model construction we recommend the 1mm rods. The 1mm silver braided bars are easy to carry with the hand and can be easily melted with small burners. For larger parts we prefer the 1.5 mm silver solder bars. With these rods you get faster material to the soldering point if needed. What can be brazed?The following materials can be combined with silver solder: brass, copper, gunmetal, gray cast iron, rusting steels and stainless steel. A combination of the materials among each other is easily possible with this silver braze solder. If the material is not known to you, it is always recommended to solder a piece to the sample beforehand. This allows you to determine whether the materials can be combined with the silver braze.Instructions Brazing with silver solder If you have never worked on silver solder and you are not sure how the exact solder brazing procedure is with silver solder, we can help you before you buy the silver solder. We have created a guide for you in our Bengs Modellbaumagazin on the topic "Brazing with silver solder". Here you can find out what you need and have to consider if you want to solder 2 components with silver solder. Tip: Flux residues and discoloration of the material can be optimally eliminated with our satin brushes or abrasive fleece!Characteristics of the silver solder bars500 mm long. 1mm or 1.5mm diameter Silver solder bars L-Ag55 (55% silver) Working temperature 630 ° C Bengs Modellbau has used this silver solder bars for years.
