CR CONNECTORS FOR CORRUGATED FLEXIBLE CONDUITS AND RIGID PIPES

Temperature range (application, installation):
from -25°C to +125°C (Intermittent +180 °C)
Flexibility: pliable
Flammability: self-extinguishing HB (Ul94)
Material: self-extinguishing polyamide 6 (Pa6)

Application:
– the connecting rings are dedicated for corrugated flexible conduits and rigid pipes,
– the advantage is easy and quick connection,
– adequately designed longitudinal section enables to connect both corrugated flexible conduits and corrugated conduit with electrical pipe.

Characteristics of material:
Free from halogen, phosphorus and cadmium, self-extinguishing/flame retardant, high-bending and crack resistance, well balanced elongation and elasticity behaviour as well as high abrasion-resistance, high tensile strength, rigidity, high impact strength, very large thermal resistance, resistance to the most of chemical compounds.
