A dry boom is effectively a sprayer boom that is fed only by hoses, and does not include any liquid filled boom pipe. Conversely, a boom that is fed by pipe/tube is generally referred to as a «wet boom».
Dry booms are typically used with smaller sprayers, as they can provide lightweight, low footprint spray booms for less complicated sprayer needs.
Different Styles of Wilger Dry Boom Nozzle Bodies & Components
Hose Barb Fed
Hose barb fed dry boom nozzle bodies come in one-way and two-way configurations, in both 3/8″ and 1/2″ hose shanks.
Square-mount and flange-mount mounting styles are available.
Compact bodies are available in push-in tube feeds as well as NPT-F feeds.
Popularly used as in-line check valves.

All NPT-F dry boom bodies are square mount compatible.
