SAE 100R12 / R13 / R15 standards
Spiral Hoses — High Pressure
Four to six spiral layers of high-tensile steel wire designed to resist extreme pressures and repeated pressure surges. The R13 and R15 withstand millions of impulse cycles without degradation — the benchmark for hydrostatic transmissions and heavy earthmoving equipment where downtime is not an option.
High pressure
4 to 6 steel plies
Impulse resistance
