Diesel Exhaust Fluid Containers and Parts

Con-Tech provides Diesel Exhaust Fluid (DEF) Spouts to improve dispensing time for DEF additives and eliminate the need for vented jugs. Con-Tech’s DEF spouts bring to you many significant features including easy attachment to the bottleneck, smooth fluid flow, no leaks or spillage during dispensing and availability in different colors. Con-Tech also has availability in customized DEF spouts as well.

Beginning of DEF Spouts

Con-Tech responded to the needs of the DEF marketplace and began to offer DEF spouts, the plastic flexible tubes used to dispense DEF from a container. Con-Tech DEF spouts are offered in standard, vented or collapsible DEF spout versions. Con-Tech DEF spouts can be used to dispense DEF typically from 1-gallon, 2-gallon, 2.5-gallon, and 5-gallon jugs and are available in 38mm, 45mm, and 63mm sizes.

Definition of DEF

DEF is a mixture of synthetic, high-purity, automotive-grade urea and deionized water. DEF is clear, nontoxic, nonflammable, non-explosive, and generally nonhazardous. DEF was developed after the Environmental Protection Agency (EPA) began to require lower emissions in response to the major amendments to the Clean Air Act. In 2008, the EPA mandated all three-quarter-ton and larger trucks have diesel particulate filters installed. Then in 2010, the EPA required that medium and heavy-duty vehicles reduce engine emissions.

DEF is safe to handle but should be stored in clean, well-ventilated areas away from direct sun. DEF can access single and bulk use dispensers as well as with DEF pumps in some locations. The DEF should meet ISO purity standards to ensure it meets the goal of protecting the environment.

DEF Market in the United States

Significantly, this EPA ruling required diesel engines to use DEF to reduce harmful emissions and satisfy the mandates of the Clean Air Act. Thus, a strong new DEF market was created in the United States.

As diesel engine trucks required DEF fluid on an ongoing basis, commercial fuel services outlets throughout the country began to sell DEF in jugs. When the need for different size jugs emerged, a market for DEF spouts was born. Recent market surveys and industry leaders indicate that the DEF spout and accessories market will continue to grow in the next five years.

Recent Developments in DEF

The DEF market is constantly changing to meet demand. During the COVID pandemic, China restricted its exports of urea, a key component in DEF. These restrictions affected everyone from truckers in Australia and farmers in South Korea to RV owners in America. We were able to serve the marketplace during this troubled time and help serve our customers’ needs.

Con-Tech is excited to be working with suppliers and consumers of this growing market.
