The Koch-Chemie Auslaufhahn is a simple but highly practical accessory for anyone regularly using larger detailing chemical containers. Pouring directly from 5L or 10L bottles can be awkward, heavy and messy, especially when transferring concentrated products into smaller bottles for dilution or daily use.

This dispensing tap solves that problem by allowing controlled product flow directly from the container. Instead of lifting and tipping large bottles repeatedly, the tap helps detailers dispense chemicals more accurately while reducing spills, drips and unnecessary waste.

For professional detailers, workshops and high-volume users, the Auslaufhahn helps improve workflow efficiency and chemical handling safety while also keeping shelves and workspaces cleaner.

The durable chemical-resistant construction is designed for repeated workshop use and quick installation directly onto compatible Koch Chemie containers.

Pro Tip

Use dedicated labelled dilution bottles alongside the Auslaufhahn to create repeatable dilution ratios for APCs, wheel cleaners and interior products. This improves consistency across detailing jobs while significantly reducing wasted product from over-pouring.

For high-volume products like Green Star or Gentle Snow Foam, the tap also helps reduce physical strain from repeatedly lifting heavy 5L or 10L containers throughout the day.
