DEF

DEF (Diesel Exhaust Fluid) hose assemblies are engineered components designed for the transfer of diesel exhaust fluid in selective catalytic reduction (SCR) systems used to reduce nitrogen oxide emissions from diesel engines. These assemblies are constructed with a black hose that has a temperature range of -40° to 140° F, ensuring reliable performance in a variety of operating environments. The hose inside diameter is 3/4 inch, and the assemblies feature stainless steel male x stainless steel male end connections, providing corrosion resistance and durability in fluid handling applications. 3G Electric supplies a range of DEF hose assemblies in multiple lengths, including 5 ft, 8 ft, 10 ft, 12 ft, 15 ft, 20 ft, 25 ft, and 50 ft, with corresponding SKUs such as 878UF9, 878UG0, 878UG1, 878UG2, 878UG3, 878UG4, 878UG5, and 878UG6. These assemblies are suitable for use in industrial, commercial, and mobile equipment where DEF is dispensed or transferred. The stainless steel fittings resist corrosion from the urea-based fluid, and the hose material is formulated to withstand the chemical properties of DEF without degradation. 3G Electric supports procurement specialists and maintenance managers by offering these assemblies as off-the-shelf components, enabling quick replacement or installation in DEF handling systems. The assemblies are available for global shipment, and 3G Electric provides logistics support to facilitate delivery to various regions. For plant engineers and maintenance teams, these DEF hose assemblies offer a standardized solution for connecting DEF tanks, pumps, and dispensing units, with lengths that accommodate different layout requirements. The consistent 3/4-inch inside diameter ensures compatibility with common DEF system components, while the stainless steel ends provide secure connections that resist leaks. 3G Electric's inventory of DEF hose assemblies allows for efficient sourcing without the need for custom fabrication, reducing downtime in maintenance operations.

Frequently asked questions

Common questions about DEF from 3G Electric.

What materials are used in DEF hose assemblies supplied by 3G Electric?

The DEF hose assemblies supplied by 3G Electric feature a black hose with a temperature range of -40° to 140° F, and stainless steel male x stainless steel male end connections. The hose material is formulated to resist the corrosive effects of diesel exhaust fluid, which contains urea. The stainless steel fittings provide additional corrosion resistance and mechanical strength, ensuring long service life in DEF transfer applications.

What lengths are available for DEF hose assemblies from 3G Electric?

3G Electric offers DEF hose assemblies in lengths of 5 ft, 8 ft, 10 ft, 12 ft, 15 ft, 20 ft, 25 ft, and 50 ft. These correspond to SKUs 878UF9, 878UG0, 878UG1, 878UG2, 878UG3, 878UG4, 878UG5, and 878UG6 respectively. All assemblies have a 3/4-inch inside diameter and stainless steel male x stainless steel male end connections.

Can DEF hose assemblies from 3G Electric be used in outdoor environments?

Yes, the DEF hose assemblies are rated for a temperature range of -40° to 140° F, making them suitable for outdoor use in many climates. The black hose material and stainless steel fittings provide resistance to UV exposure and corrosion, though prolonged direct sunlight may affect the hose over time. For extreme conditions, consult the manufacturer's guidelines for specific environmental limits.

Are the stainless steel fittings on DEF hose assemblies compatible with standard DEF system components?

The stainless steel male x stainless steel male end connections on these assemblies are designed to mate with standard female threaded ports commonly found in DEF tanks, pumps, and dispensing equipment. The 3/4-inch inside diameter ensures compatibility with typical DEF system plumbing. Always verify thread specifications and port dimensions with your system components before installation.

What is the typical application for DEF hose assemblies with 3/4-inch inside diameter?

DEF hose assemblies with a 3/4-inch inside diameter are commonly used in diesel exhaust fluid transfer systems for medium to large diesel engines, such as those in trucks, buses, construction equipment, and industrial generators. They connect DEF storage tanks to dispensing units or directly to SCR system components, facilitating the delivery of DEF for emissions reduction.
