Safety valve

Connecting sleeves for soldering into the steam boiler with two different fine threads. The soldering connection sleeves are inserted into a hole with a 10 mm diameter and can then be soldered hard or soft. The beeches are made of brass MS58. Thanks to the soldering connection sleeves, the parts attached to the steam boiler have a sufficiently stable and long screw-in thread. The solder connection sleeve M6x0.75 fits our boiler accessories.The solder connection sleeve e M8x0.75 fits our safety valve with weight  The socket dimensions are always the same: Soldering diameter: 10mm Bundle diameter: 12mm Height: 10mm

A water level indicator is used to read the water level in the steam boiler. Our water level indicators consist of 2 angle pieces that are connected by a glass tube. Since it is dangerous for the boiler to run dry, it is always recommended to install a water level indicator. At Bengs Modellbau you have the choice between a light and a heavy version. Depending on how big your steam boiler is, you can choose the right variant. The water level indicator is made of brass, hard soldered and sandblasted. For assembly, a shaft can be pushed by unscrewing the sealing plugs. This is used for precise alignment of the screw-in bodies. If the glass breaks, the tube can be changed in no time. The water level indicator comes with a 100 mm long tube.Water level indicator lightweightWith a hole spacing of 60mm, the tube is visible for 35mm. Maximum hole spacing: 100mm Screw thread: M6x0.75< li> Height with union nut: 20mm Length part 1: 17mm Length part 2 with sealing plug: 26mm Largest diameter: 10mm Glass tube: 5mm x 100mmWater level indicator heavy Schott Duran glass tube is 100% sealed with graphite Teflon tape. With a hole spacing of 80mm, the tube is visible for 45mm . Maximum hole spacing: 100mm  Screw-in thread: M6x0.75 Height with union nut: 30mm  Length: 33mm  Width: 15mm  Glass tube: 5mm x 100mm

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.  

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
