Attwood 8838US6 Universal Sprayless Fuel Connector for 3/8 Inch and 5/16 Inch Fuel Line

The Attwood 8838US6 Universal Sprayless Connector is a male and female fuel fitting set designed to replace traditional threaded tank fittings on outboard and I/O fuel systems. Its Universal Sprayless Connector design eliminates the spray of fuel that typically occurs when connecting or disconnecting fuel lines, making fuel line service cleaner and safer. The high-strength plastic body is engineered to withstand the harsh marine environment, resisting the effects of sun, moisture, and fuel exposure over time.

Both the female hose fitting and male hose fitting are compatible with 3/8 inch and 5/16 inch fuel lines, giving it broad compatibility across common boat fuel hose sizes. The male tank fitting comes with pre-applied fuel-grade thread sealant and fits all standard 1/4 inch NPT fittings, so it threads directly into existing tank ports without a separate sealant application. Both the male and female connectors include automatic check valves that close on disconnect, preventing fuel from leaking out when the line is uncoupled. The fitting is rated for high fuel flow, with less than 0.25 kPa of restriction at 50 liters per hour, and is compatible with ethanol-blended fuels as well as all OEM brand engines.
