Leak-Free Performance

Our Flush Port Quick Connects are engineered with a double O-ring design that ensures a tight, leak-free seal every time. Note: Yamaha and Honda models feature double O-rings in the male segment while the Mercury and Suzuki feature a proprietary design with one O-ring each in the male and female segments.

Female Quick Connects

FLUSHMASTER offers the only marine-grade female quick connect available on the market. Designed with a marine-grade 316 stainless steel (SS) spring, this quick connect is built to resist rust and corrosion. No other female quick connects on the market are made to this standard.

Hassle-Free

No more wasting time screwing around with your OEM flush port plug. Our Flush Port Quick Connect permanently replaces the OEM, giving you convenience instead of a headache.

Saves Time

Get a quick connection every time you go to flush your outboards. Twist off the cap, connect the hose, flush, disconnect, and twist the cap back on. It’s that easy!
