When it comes to ensuring the perfect pour of your draft beer, the unseen heroes of the system are the jumper lines. These often-overlooked components play a crucial role in maintaining the integrity and quality of your beer from keg to glass. Their main purpose is to create the right amount of pressure for a continuous flow of beer, which helps the beer’s consistency remain steady.

In this blog, we’ll delve into the ins and outs of jumper lines, exploring their purpose, the need for regular replacement, and how Glacier Design Systems can assist in keeping your beer lines in top-notch condition.

Understanding Jumper Lines

Jumper lines are clear lines made of vinyl flex tubing. They connect the trunk to the keg couplers inside the cooler, ensuring a seamless flow of beer from the keg to the dispensing system. In addition to vinyl, carbon dioxide, and nitrogen beer gas lines are also commonly made with this flexible material. While vinyl’s flexibility and resistance to kinking make it ideal for this application, it’s important to note that vinyl is not food-grade material. Consequently, Glacier recommends replacing these lines annually to prevent the buildup of sugar, protein and microbial deposits that can compromise the quality of your draft beer.

Why Replace Jumper Lines Annually?

Unlike polyethylene, vinyl has a porous surface that can harbor contaminants over time. The accumulation of sugar, protein and microbial deposits can lead to permanent infections in the draft beer system. To maintain the freshness and purity of your beer, it’s essential to replace your jumper lines each year. 

Regular replacement not only ensures the cleanliness of your system but also contributes to the overall longevity and performance of your draft beer setup. Draft systems are comprised of several components that all function together, so maintaining each of these features will help your system pour better over time.
