Fittings are made of polypropylene B and their features are:

• a perfect resistance to low and high temperatures;

• a high resistance to mechanical and chemical damage;

• a high and constant stiffness in various climatic and instalment conditions;

• a high resistance to strokes at temperatures of 20o C minus, which is very important for their instalment at low temperatures in winter;

• resistance to sewage at temperatures of 95oC (in emergency up to 110oC);

• resistance to miscellaneous chemical sewage 

The perfect smoothness of our fittings reduces the risk of a bigger sedimentation. The fittings are made according to the norm PN-EN 1451.
The products made by CERTUS have superb hydraulic properties (noise level reduction of the sewage flowing through)
