Polyamide nucleus 6.0 (Nylon) + 30% fiberglass charge. Copper external cover (Cu) 99.9%. Minimum and maximum working temperatures, from -20º to + 105ºC. Inner threads for gas according with Standard DIN-2999. Maximum working pressure: PN-16. Inflammability: Self-extinguishing. Dielectric stiffness: 50 Kv / mm2. Traction resistance: 7.44 kg / mm2. Bending resistance: 7.75 kg / mm2. Resistance to compression: 6.32 kg / mm2. Elongation at break: 20-200%.
Especially indicated for installations where there are elements of different nature and composition. Example: (copper / iron), ensuring the elimination of galvanic pairs.
Excessive tightening of the metal part on the coupling causes an overload situation. The deterioration of Polyamide, is accelerated by the combination of mechanical aggressions (load stresses, vibrations, etc.) and thermal (high temperatures).
