Attwood Universal Sprayless Connector – Hose Male (5/16"-3/8")

The Attwood Universal Sprayless Connector – Hose Male (5/16"-3/8") is a marine-grade fuel and water line fitting engineered to eliminate the spray and spillage that plague traditional quick-disconnect couplers. Built for serious boaters who demand reliability and cleanliness during fuel transfer, engine flushing, or livewell operations, this connector solves a real problem on the water: messy, unpredictable fluid transfer that leaves fuel stains on the hull and deck. Whether you're running fuel lines to portable tanks, connecting freshwater systems, or managing engine cooling loops, the sprayless design keeps your boat dry and your operations professional-grade.

This hose male connector features Attwood's proven sprayless technology—an internal ball-check valve that seals the connection instantly upon disconnection, preventing backflow and eliminating the fuel or water spray that occurs with conventional fittings. The universal 5/16"-3/8" sizing accommodates standard marine hose diameters used across most recreational and commercial vessels, making it a versatile upgrade to aging or problematic fuel systems. The connector body is crafted from corrosion-resistant materials suitable for saltwater and freshwater environments, ensuring longevity in harsh marine conditions where standard fittings degrade quickly. Installation is straightforward—simply barb or crimp the hose onto the male fitting, then pair it with the corresponding sprayless female connector for a sealed, leak-free system.

Boaters transferring fuel between tanks, owners upgrading aging livewell systems, and anyone managing multiple water or fuel lines will immediately appreciate the sprayless design's practical benefits—no more wiping down the transom after fueling or flushing the engine. The connector is compatible with standard barbed or crimped hose installations and works seamlessly with Attwood's full line of sprayless female connectors to create a completely sealed system. Installation requires no special tools beyond basic hose-clamp equipment, and the connector performs reliably in temperatures and conditions typical of freshwater lakes and coastal saltwater applications. This is a straightforward, effective upgrade for any boat owner tired of fuel spills and water mess during routine maintenance and operation.
