High-Performance Anti Static Hydraulic Hose for Demanding Industrial Applications
1. Product Overview
In fluid power systems where volatile environments and sensitive electronics coexist, standard hydraulic hoses pose a significant risk. An anti static hydraulic hose is engineered to dissipate electrostatic charges safely, preventing spark ignition in flammable atmospheres and protecting sensitive instrumentation from electrical interference. Our premium series of anti static hydraulic hoses combines advanced rubber compound technology with robust reinforcement layers to deliver reliable conductivity, high pressure resistance, and exceptional flexibility. Designed for the most stringent international safety standards, these hoses are the definitive choice for refineries, chemical plants, and explosive material handling facilities.
2. Key Features
- Static Dissipation Mechanism: Conductive rubber lining and carbon-black infused layers ensure a surface resistance of less than 1 × 10⁶ Ω/m, safely channeling static charges to the end fittings.
- High Pressure Integrity: Double steel wire braid reinforcement (2SN/DIN EN 856) provides working pressures up to 420 bar (6,090 psi), with a 4:1 safety factor.
- Broad Temperature Range: Serviceable from -40°C to +100°C (-40°F to +212°F), suitable for extreme climatic and process conditions.
- Oil & Abrasion Resistance: Outer cover formulated with enhanced NBR/PVC blends resists hydraulic oils, fuels, and mechanical wear, extending service life in harsh environments.
- Traceable Certification: Each hose length is marked with batch numbers and tested for electrical continuity, ensuring full compliance with ISO 8031 and EN 12115 standards.

7. FAQ
Q: How does an anti static hydraulic hose differ from a standard hydraulic hose?
A: Unlike standard hoses, an anti static hose incorporates conductive materials in the inner tube and cover, creating a low-resistance path to ground. Standard hoses can accumulate static charges of several thousand volts, while our design limits surface resistance to below 1 MΩ/m.
Q: Can this hose be used for steam cleaning?
A: No. The maximum operating temperature is 100°C (212°F). For steam applications, please refer to our specialized steam hose series.
Q: Do I need special fittings for the anti static feature?
A: Standard carbon steel or stainless steel fittings work effectively, provided they make metal-to-metal contact with the hose's conductive inner layer. We recommend crimped fittings with exposed wire braid contact for optimal continuity.
Q: How often should the electrical resistance be tested in service?
A: We recommend testing every 6 months using a megohmmeter (500V DC) between end fittings. Replace the hose if resistance exceeds 1 × 10⁶ Ω/m.
Q: Is this hose suitable for food-grade applications?
A: No. This hose is formulated for industrial hydraulic fluids. For food contact, please request our FDA-compliant anti static hose series.
Q: What is the minimum order quantity?
A: For standard sizes (1/4" to 1"), the MOQ is 50 meters. For larger diameters or custom assemblies, please contact our sales team for tailored solutions.
