How to choose a gun for mounting foam

The principle of operation of any mounting pistol is the same. At the same time, they differ in materials as well as at the price. In order not to be confused in the choice, answer for a start to such a question: how often do you plan to work with it? If you constantly, then you will need the most enduring and, of course, an expensive option. For disposable work, you can choose a very simple and affordable. What to pay attention to when buying?

The main material from which the gun for mounting foam is made. The larger in it parts of plastic, the smaller his life. But the price will be significantly lower than that completely cast from the metal. For disposable work is quite a good option. However, plastic also happens different. Quite often to reduce the cost of the product, as well as weight loss (which is especially relevant for professional builders) manufacturers are partially abandoned by metal in favor of high-strength plastic. Such a gun can work for quite a long time, while its cost will be lower than fully metallic. In a high-quality pistol, the tube, the needle and the holder will necessarily be made of metal, but at the same time pay attention to the spike nodes - than they are accurately fulfilled, the better.

Make sure that all the details are easily unscrewed and are collected back. Since after work you will need to clean the gun with the help of a special solvent, this indicator will be relevant. In some very cheap models, there is no possibility to disassemble the product, that is, you really acquire a gun for one-time use or until the foam drying in the product, which can happen even before the end of work.

Check out the material from which the needle is made. Most often use steel or brass. But the Teflon coating, which are so proud of the famous brands, is found today on many products. For example, in the most affordable pistols of the company INTERTOOL and on expensive models of the company NEO there is a coverage that does not make it unique. Positive feedback can often be found about Zolder pistols. Make sure that you really sell with Teflon, and not with any other coating, quite simple: if you spend your fingers on the needle, it seems that its surface is slightly fat, and the color is inhomogeneous. If you are offered painted paint surface - it is better to refuse immediately. The paint will add only difficulties in work and quickly gets off.

Pay attention to the locking ball. It is located in the middle of the holder. Ideal for operation are balls made of steel or fluoroplastic (Teflon). It is practically no foam, as well as their service life exceeds several plastic balls.
