Product advantages
The minimum bending radius is half that required by ISO 18752.
6000 psi (42 MPa) constant pressure for all sizes.
Exceeds ISO 18752 (classes AC/BC/CC/DC).
The outer diameter is approximately 30% smaller than standard SAE coiled hose.
Twice the life under impulse loads - proven by 2,000,000 impulse test (DC class).
Bending and impulse testing ensures superior performance and long hose life.
Weight is approximately 26% less than standard SAE coiled hose.
