SteelPRES press fittings are manufactured using unalloyed steel. A galvanic zinc coating with a thickness of at least 10 microns protects against external corrosion.
SteelPRES pipes are longitudinally welded thin walled precision steel pipes conforming to DIN EN 10305-3.
Pipes are available with external galvanization, internal and external sendzimir galvanization and external galvanization coating of PP (thk 1 mm).
Dimensional range Ø12 ÷ 108 mm, siliconised EPDM O-ring with the additional safety feature that during pressure tests will lead to leakage in the case of accidentally unpressed (from Ø 15 - 54 mm).

Raccorderie Metalliche on the other hand uses a patented sealing ring with a lenticular profile which fits the press crimp groove.
SteelPRES press fitting systems produced from Raccorderie Metalliche, present the following advantages:
• A 20% enlargement of the sealing surface area
• Major reduction of the risk of the sealing ring being pressed
out or damaged.
