Johnson Pump Aerator Head - 12-¾" w/Shut Off Valve

The Johnson Pump Aerator Head with 12-¾" length and ¾" thru-hull mount is a precision spray assembly designed for live bait tank aeration on fishing vessels of all sizes. This aerator head delivers consistent water circulation and oxygenation through its integral shut-off valve, allowing anglers to control water flow independent of the through-hull fitting. Whether running a weekend recreational rig or a serious offshore boat, this aerator head maintains water quality in live wells and bait tanks during extended fishing operations.

The 12-¾" overall length accommodates standard thru-hull installations on transom-mounted live wells, while the ¾" connection diameter matches common marine plumbing configurations. The integrated shut-off valve enables precise control over aeration flow, preventing over-oxygenation and unnecessary water loss when the boat is idle or between fishing spots. Johnson Pump's modular spray head design allows this assembly to be customized to specific vessel requirements—different spray patterns, configurations, and flow capacities can be adapted to match your particular hull layout and tank volume. The compact 0.3 lb weight and 5" x 2" x 13" footprint fit standard transom installations without requiring extensive modifications.

This aerator head is essential for weekend anglers and commercial fishing operations where bait and catch quality depend on stable water temperature and oxygen levels. Recreational fishermen running stripers, tuna, or large saltwater gamefish rely on live bait systems to maximize strike rates, making reliable aeration equipment non-negotiable. In coastal and offshore saltwater environments, Johnson Pump components are proven to withstand repeated exposure to corrosive conditions when properly maintained. The shut-off valve design reduces stress on live specimens by preventing excessive turbulence during idle periods, extending bait viability over full-day trips.
