THREADS
Threads: R external taper threads, Rp internal straight threads made in acc. with the PN-ISO 7-1 standard, G fastening threads made in acc. with the PN-ISO 228-1 standard.
SURFACE / ZINC COATING
EE fittings can be supplied with black or zinc-coated surface, depending on the order.
According to EN 10242, the surface-related mass of the zinc coating is greater than 500 g/m2, which corresponds to the average film thickness of 70 µm.
Both black and zinc-coated surfaces are protected against corrosion.
The corrosion protection does not contain polycyclic aromatic hydrocarbons.
WORKING PRESSURE
– 2,5 MPa / 25 bars / temperature between -20oC and 120oC
– 2,0 MPa / 20 bars / temperature 300oC
– between 120oC and 300oC interpolated

LEAKPROOFNESS TESTING
In accordance with the PN-EN 10242 standard, each EE fitting is tested for leaks under a compressed air pressure of at least 0.5 MPa /5 bar/ which is equivalent to a hydrostatic pressure of at least 2.0 MPa /20 bar/.
DESIGN
Technical aspects, appearance and other characteristics of fittings may be modified in line with technical progress and in accordance with changes in the applicable standards.
