Livewell - Aerator Heads, Fittings, Connectors

Why Livewell Aerator Heads, Fittings & Connectors Matter

For any angler who takes their catch seriously, a properly functioning livewell is non-negotiable. Whether you're headed to a tournament weigh-in or simply want to keep live bait fresh throughout the day, the small plumbing components that make up your livewell system — aerator heads, thru-hull fittings, connectors, strainers, and overflow tubes — are what stand between a healthy catch and a dead one. These parts may not look impressive on a workbench, but on the water, they do the essential work of circulating oxygenated water and maintaining the right environment inside the tank.

Understanding the Key Components

A livewell plumbing circuit is made up of several distinct part types, each serving a specific role:

• Aerator spray heads mount inside the livewell tank wall and direct water in a fine spray pattern to maximize surface agitation and oxygen transfer. They are available in single-valve, double-valve, adjustable, and non-adjustable styles.
• Thru-hull connectors provide a watertight passage for hose runs through the transom, bulkhead, or livewell wall — commonly available in straight and 90-degree configurations to accommodate tight installations.
• Strainers and filters are mesh or dome-style screens that attach to pump inlets or thru-hull fittings to prevent trash, scales, and debris from entering the pump and causing premature wear.
• Overflow drain tubes and fittings maintain proper water level in the livewell by allowing excess water to exit the tank while retaining fish, available in screw-in and push-in styles to match different tank designs.
• Hose barbs, adapters, and valve assemblies connect hose sections, change hose diameters, and provide on/off shutoff control within the plumbing circuit.

What to Look for When Shopping

Material selection is critical in marine environments. Look for components made from ABS plastic, acetal, or polypropylene, as these resist the corrosion and UV degradation that quickly degrade lower-quality parts. Thread compatibility is equally important — confirm that spray heads and connectors match your existing pump outlets and hose diameter (typically 3/4" ID for most bass and fishing boat setups). For installations in tight spaces, 90-degree fittings and elbow connectors can simplify routing and reduce hose stress.
