High Pulse Constant Pressure Type Hydraulic Hose ISO18752
ISO18752 hydraulic hose for high-pulse constant-pressure service with AC, BC, CC, and DC series coverage.
ISO18752
This ISO18752 hose is designed for constant-pressure hydraulic systems that require high pulse-cycle resistance.
- AC, BC, CC, and DC series cover different pulse-cycle requirements from 200,000 up to 1,000,000 cycles.
- The hose uses an oil-resistant tube with steel-wire braid or spiral reinforcement and a weather-resistant cover.
- It is intended for petroleum-based hydraulic fluids and water service within the stated temperature range.
