The 10.000 series, double cone fittings are called "Universal" to underline the vastness of their fields of application and the adaptability of this type of fitting. The clamping of the tube is realized by means of the compression of one ring called "Double Cone" or "Olive", for its taper shape at the ends. The seat which fits on the body fitting and the olive, are dimensioned in conformity with the DIN Standards 3862, except the sizes 14, 16, 18 and 22, which are not detailed in specification.
Temperatures and Pressures
The working pressures and working temperatures depend on which type of tube is used, for this reason, the values must be determined in accordance with the tube's features. Hereunder, we specify the values of the maximum pressure advised for the fittings at a temperature of 20°C connected with copper tube, which has a thickness of 1 mm.
The values of working pressures advised, specified in table have been obtained from the test values using a Safety Factor 4. It is available the test report made by the external laboratory test.

Assembling Instruction Series 10000
To ensure the best function of our fittings, please follow the under mentioned istructions, in order to avoid wasted of time and bad applications of the product.
| 1 Cut the tube at 90° and remove internal and external burrs. |
|
2 Lighty oil the tube nut, olive and fitting thread. Slide the nut and olive onto the tube ensuring that the sharp side of the olive is facing the fitting.
|
|
|
3 Screw the nut onto the fitting by hand until hand-tight.
|
|
4 Ensure the tube is pushed fully home into the fitting before tightening the nut with the correct spanner.
|
|
|
5 Tighten the nut with the spanner one and a quarter turns, marking reference points, if necessary.
|
|
6 To ensure that the olive has gripped the tube correctly. Unscrew the nut and make sure that the groove made by the olive is even.
|
|
|
7 Tighten the nut again with an extra quarter turn. Additional information to ensure correct assembly, where fitting to curved tubes ensure that the section entering the fitting is straight for a minimum length of twice the nut height.
