When it comes to food safety, attention is often focused on finished products or visible kitchen equipment. However, a large part of the reliability of a system relies on invisible but essential components: the fittings. The 4200 series in POM stands out as a reference solution, thanks to its smart design, versatility, and compliance with international food safety standards.
A series designed for food, water, air, vacuum... and more
The 4200 series includes push-in instant fittings, suitable for food liquid transport, drinking water, compressed air, certain gases, as well as vacuum applications. Their design allows for quick, tool-free connection, with excellent retention even under pressure or vacuum.
They are made from POM (polyoxymethylene), a rigid, reliable material compatible with the strictest sanitary requirements.

Certifications and compliance
The fittings in the 4200 series comply with the main European and international regulations related to food contact:
NSF 51 & 61: US standards for materials used with food and drinking water
RoHS 2: Compliance with the directive on restricting hazardous substances in electrical equipment
REACH: EU regulation ensuring a high level of health and environmental protection
CE 1935/2004: EU regulation on materials intended for contact with foodstuffs
DM 174/2004: Italian decree regulating materials in contact with drinking water in fixed installations
Where are these fittings used?
The 4200 series is used in a wide variety of equipment:
Vending machines
Water filtration and treatment systems
Compressed air circuits for food applications
Liquid dosing and transfer installations
Household and semi-professional appliances (beverage machines, fountains…)
And in Italian coffee machines, for example?
A particularly interesting application area is domestic or semi-professional Italian coffee machines, such as those offered by Gaggia, De’Longhi, or Saeco.
These appliances use fittings like those in the 4200 series to ensure the water circulation within the internal parts of the machine, especially upstream of the heating chamber. Their compatibility with food-grade tubes, thermal resistance, and ease of installation make them ideal for such uses.
