SteelPRES VdS-FM press fittings are manufactured using unalloyed steel. A galvanic zinc coating with a thickness of at least 10 microns protects against external and internal corrosion.
SteelPRES VdS-FM pipes are longitudinally welded thin walled precision steel pipes conforming to DIN EN 10305-3.
SteelPRES VdS-FM press fitting system is designed and certified to use in wet sprinkler systems (plant full of water).
Pipes are with internal and external sendzimir galvanization, without coating.
Dimensional range Ø22 ÷ 54 mm, red MVQ O-ring.

Raccorderie Metalliche on the other hand uses a patented sealing ring with a
lenticular profile which fits the press crimp groove.
SteelPRES VdS-FM 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.
