21GU-H21 DEF Hose Assembly: Premium Solution for AdBlue Dispensing Systems
This high-performance DEF hose assembly is engineered to meet the rigorous demands of urea-based fluid dispensing systems, particularly for Gilbarco, OPW and Piusi equipment. Constructed with EPDM (ethylene propylene diene monomer) material, it combines durability, chemical resistance, and longevity, matching the quality of steel and textile braided hoses from the same manufacturer.
Material & Design
EPDM Hose: Resists UV, ozone, and temperature fluctuations (-40°C to +120°C), ensuring reliability in harsh environments.
Fluoropolymer Lining: Smooth, seamless interior minimizes flow resistance and prevents clogging, optimizing DEF delivery efficiency.
Textile Braiding: Enhances pressure resistance and flexibility while maintaining structural integrity.
Connectivity & Installation
Female BSPP Swivel Couplings: Chrome-plated brass ends with 1" BSP (British Standard Pipe Parallel) threads for secure, leak-proof connections.
Anti-Kinking Sleeve: At the nozzle end, this sleeve prevents hose distortion during frequent use, extending service life.
Torque Guidance: Recommended installation torque of 30–37 ft-lbs (40–50 Nm) ensures proper sealing without over-tightening.
Performance & Compliance
ISO 22241 Certification: Meets stringent international standards for urea dispensing systems, guaranteeing compatibility and longevity.
Flow Efficiency: 16mm inner diameter (5/8") and 26mm outer diameter (1") balance flexibility with robustness.
Bend Radius: Minimum 3.5" (90mm) to avoid stress-induced damage during operation.
Applications
Ideal for agricultural, industrial, and automotive DEF dispensing systems requiring reliable fluid transfer.
Suitable for both stationary and mobile installations, such as refueling stations, fleet maintenance centers, and urea storage facilities.
Advantages Over Competitors
Lightweight & Flexible: Easy to maneuver and install, reducing labor time.
Cost-Effective Longevity: Reduced downtime and replacement costs due to static bonding and anti-corrosion design.
European Standard Compliance: Recognized as the de facto standard in Europe, ensuring seamless integration with regional equipment.
Available Lengths
Choose from 4m, 6m, or 10m assemblies to suit specific operational needs.
Installation & Maintenance Tips
Regularly inspect swivel couplings for wear and ensure proper torque adherence.
Store in a cool, dry environment to prevent UV degradation.
Pair with compatible DEF filters and pumps for optimal system performance.
This hose assembly represents a robust, future-proof solution for DEF applications, combining innovation with proven reliability.
