Description
Def Diesel Exhaust Fluid Hose, Def Hoses DN19
In the modern era of diesel engine operation, adhering to stringent emissions standards is not just a recommendation—it's a requirement. At the heart of every Selective Catalytic Reduction (SCR) system is Diesel Exhaust Fluid (DEF), a high-purity solution of 32.5% urea and deionized water. The integrity of your entire emissions control system depends on the flawless handling and transfer of this sensitive fluid. Introducing our premium DEF Transfer Hose DN19—a purpose-engineered solution designed to set the new benchmark for reliability, safety, and performance in fluid handling systems.
Engineered for the Unique Demands of Urea-Based Fluids
Not all hoses are created equal. Standard fuel or water hoses are completely unsuitable for DEF transfer, as they can contaminate the fluid or degrade rapidly. Our DEF Hose is meticulously manufactured from specifically formulated materials that are fully compatible with aqueous urea solutions.
-
Premium EPDM Inner Tube: The core of our hose features a smooth, non-porous tube made from high-grade Ethylene Propylene Diene Monomer (EPDM). This material is chemically inert to DEF, preventing any interaction that could lead to fluid contamination, crystallization, or a breakdown of the hose from the inside out. The ultra-smooth bore ensures minimal flow resistance and prevents the build-up of urea deposits.
-
Robust Reinforcement Layer: To ensure durability and kink resistance, the hose is reinforced with a high-tensile textile braid. This layer provides excellent pressure handling capabilities, making it ideal for both suction and discharge applications in various transfer scenarios.
-
Abrasion-Resistant & Weatherproof Cover: The exterior is sheathed in a tough, synthetic rubber cover that is resistant to abrasion, weathering, ozone, UV radiation, and extreme temperatures. This protective layer safeguards the hose's integrity against the harsh conditions often found in workshops, farms, mining sites, and transportation hubs.
-
ISO 22241 Compliant: Our hose is designed and tested to meet or exceed the requirements of ISO 22241, the international standard that governs the quality, handling, and transportation of Diesel Exhaust Fluid. This guarantees that the hose will not leach contaminants that could deplete the fluid's purity and compromise your SCR system.
Key Features and Unmatched Benefits:
-
Superior DEF/AdBlue Compatibility: Certified for use with all urea-based fluids, ensuring zero contamination and protecting your valuable SCR catalysts and injectors from expensive damage.
-
Optimal DN19 (3/4") Diameter: The 19mm internal diameter provides an ideal balance between flow rate and handling flexibility, making it perfect for bulk transfer, dispensing, and storage applications.
-
Excellent Flexibility & Kink Resistance: Despite its rugged construction, the hose remains highly flexible even in cold temperatures, allowing for easy maneuvering around equipment and preventing frustrating kinks that interrupt flow.
-
Temperature Resilience: Maintains its integrity and performance across a wide operational temperature range (from approximately -40°C to +70°C / -40°F to +158°F), crucial for DEF which freezes at -11°C (12°F).
-
Low Permeability: The multi-layer construction significantly reduces vapor transmission, helping to maintain the concentration and quality of the DEF over time.
Comprehensive Applications for Your Fluid Transfer Needs
Our versatile DEF Hose DN19 is the critical link in a wide array of fluid transfer systems. It is the ideal choice for:
-
Bulk DEF Storage Tanks: Connecting tanks to pumps and dispensers.
-
DEF Dispensing Equipment: As a replacement or upgrade hose on DEF pumps at fuel stations, truck stops, and fleet yards.
-
Transportation and Delivery: For use on DEF delivery trucks and trailers for offloading fluid into stationary storage tanks.
-
Fleet Maintenance Facilities: For transferring DEF from storage totes or drums to vehicles, including trucks, buses, construction equipment, and agricultural machinery (tractors, combines).
-
Stationary SCR Systems: Used in generator sets and industrial power units.
