Mechanical processing workshops, construction equipment, hydraulic workshops and transportation supporting systems need stable delivery of hydraulic oil, lubricating oil and industrial fuel oil. Different devices differ in required oil flow, pipeline installation space and working pressure. Single-size and single-pressure hoses cannot meet collocation needs of fine control pipelines and large-flow main pipelines. EPDM rubber oil hose covers complete DN6-DN100 calibers with working pressure ranging from 1000 PSI to 6000 PSI. This multi-spec industrial pipeline realizes matched oil transportation under different pressure loads, adapting to flexible pipeline layout of various oil circulation systems.

EPDM rubber serves as the primary raw material for inner tube and outer cover of the oil hose. The inner EPDM lining features stable chemical inertness against long-term contact with hydraulic oil, lubricating oil and general industrial oils. It resists swelling, dissolution and hardening caused by continuous medium erosion, keeping inner wall smooth to reduce fluid resistance and avoid pipeline clogging. Modified EPDM formula adds anti-aging fillers for the outer layer, bringing prominent resistance to ozone, ultraviolet ray and temperature aging. The outer rubber tolerates repeated friction in workshop environments, indoor high temperature and outdoor light exposure, delaying cracking and degradation. The material also withstands temperature fluctuation during equipment startup and shutdown for stable long-cycle operation.

The product series achieves layered pressure design covering 1000 PSI up to 6000 PSI to match differentiated load intensity. 1000 PSI to 2000 PSI hoses suit light-load scenarios including small machine tools, household hydraulic equipment and general assembly machinery with stable low-pressure oil circulation. 2500 PSI to 4000 PSI specifications apply to medium-load equipment such as forklifts, injection molding machines and road maintenance machinery, coping with regular pressure fluctuation during mechanical reciprocating movement. 4500 PSI to 6000 PSI heavy-pressure grades adapt to heavy-duty hydraulic stations, mining auxiliary equipment and large engineering machinery, resisting instantaneous pressure impact and long-time high-pressure holding. All DN6-DN100 calibers support optional pressure grades for customized matching.

The full caliber range from DN6 to DN100 forms systematic flow matching for industrial oil pipelines. Small calibers DN6, DN8, DN10, DN12 are used for precision control oil circuits, instrument oil pipelines and narrow internal wiring of compact equipment. Small sizes maintain high flexibility for bending arrangement inside dense mechanical gaps. Medium calibers DN16 to DN65 act as mainstream connecting pipelines for most factory hydraulic loops and mobile machinery oil circuits, balancing flow volume and bending practicability for most conventional industrial projects. Large calibers DN80, DN90, DN100 are applied to large-flow main oil pipelines of centralized hydraulic systems and heavy industrial equipment, lowering flow resistance to realize high-volume oil transmission with stable pressure loss. All calibers adopt unified EPDM composite forming standards for consistent basic performance.

The EPDM oil hose adopts multi-layer reinforced composite construction. High-tensile reinforcing layers are tightly integrated with EPDM rubber through high-temperature vulcanization. The reinforcement restricts radial expansion of pipe walls under rated pressure within 1000–6000 PSI, preventing bulging deformation and oil leakage. The layered bonding effectively avoids interlayer separation, bubbling and medium permeation under long-term alternating pressure and repeated bending. The pipe body retains appropriate flexibility rather than rigid stiffness, allowing multi-angle winding around equipment brackets, valves and cabinet structures without dead folds blocking fluid channels.

This series EPDM rubber oil hose is widely used across machinery manufacturing, construction engineering, agricultural machinery, metallurgy and automated production lines. All DN6-DN100 sizes fit mainstream hydraulic ferrules, pipe clamps and flange joints, supporting on-site cutting according to actual measured pipeline length. Every batch undergoes strict factory inspections including hydraulic pressure holding test, burst test, oil immersion compatibility test and bending fatigue test to verify safety within rated pressure range. The lightweight rubber material eases transportation and installation work, reducing overall equipment pipeline load.
