With these compression fittings you can connect two copper pipes or brass pipes together without soldering. A compression fitting consists of a base body, two cutting rings and two union nuts. All parts of the compression fitting are made of brass. The compression fittings can be used in both pneumatics and hydraulics. These screw connections are also used to connect lubrication lines, gasoline lines, gas lines, supply steam lines or exhaust steam lines. The compression fittings are also used in trade and industry. There are even many areas of application in model making. To crimp a pipe, the union nut is first pushed over the pipe. The cutting ring is then also pushed onto the pipe. Now the pipe can be inserted into the base body and the union nut is tightened using a wrench. When the union nut is tightened, the clamping ring is compressed so tightly that it can no longer be removed from the pipe without being destroyed. The following compression fittings are available: Straight compression fitting for 4 mm pipe / internal thread union nut M8x1 Straight compression fitting for 5 mm pipe / internal thread union nut M10x1 Straight compression fitting for 6 mm pipe / internal thread union nut M10x1 Straight compression fitting for 8 mm pipe / internal thread union nut M12x1 Straight compression fitting for 10 mm pipe / internal thread union nut M6x1.5 Suitable Copper pipe or Brass tube for the compression fitting can be found under the link.
