Draftline

Draftline is a term used across several domains with different meanings, but it generally denotes a line or conduit that carries a draft, whether a liquid, air, or a concept in a drawing. It is not a single, universally defined term.

In the beverage industry, a draft line refers to the tube or hose that transports beer from a keg to a tap. Draft lines are usually made of food-grade materials and connect refrigerated kegs to the faucet. They require regular cleaning and sanitation to maintain beer quality and prevent bacterial growth. Cleaning frequencies vary by venue and usage, but high-traffic installations are often cleaned daily or every two weeks, using approved cleaning agents and thorough rinsing.

In engineering and manufacturing, the term can appear in relation to draft angles on molded parts. A draft line on a technical drawing may indicate the direction of draft or serve as a reference line for identifying features that need to release from a mold. Draft requirements help ensure parts can be removed from tooling without damage.

In building science and HVAC contexts, draft lines describe the path of air flow into or out of a space, contributing to comfort, energy use, and infiltration analysis. Discussions of draft lines focus on minimizing unwanted drafts through design, sealing, and insulation.

Some companies use DraftLine as a brand or product name, often in reference to beverage equipment or related services. The term remains generic and adopts meanings tied to its component words in different industries.
