Built to the standard it carries.
The RX-400 is a four-spiral, high-tensile steel-wire hose for high working pressure and high-impulse hydraulic applications. Four alternating spiral layers create structural balance and stability under dynamic loads, and the spiral construction resists pressure-spike fatigue in high-cycle applications. Rated to +120°C for elevated-temperature systems.
