Eurotubi Pressfitting System - Technical Guide ... - Damstahl

For these systems, both the stainless steel and the carbon steel Eurotubi Pressfitting System can be used.
In any case it is worthwhile to remember that the operating temperature and pressure are two fundamental
elements to know when choosing the type of material. The maximum operating pressure is 16 bar.
In carbon steel systems, the presence of moisture may generate corrosion. Installing a dryer is essential.
Finally it is necessary to wet the o-rings with water before assembling the joints.
