Built for More Than Flushing.

THE BETTER WAY TO CONNECT

Upgrade your boat’s plumbing with a fitting built for the salt. This solid 316 Stainless Steel fitting replaces standard, corroded inlets with a premium quick-connect. Whether upgrading a factory flush port or adding a washdown, it gives your boat a clean, "custom-build" finish.

316 SS quick connect water inlet outlet fitting

SOLID 316 STAINLESS STEEL

Overengineered for salt. While most fittings are just plated brass, ours is solid 316 Stainless from base to cap. It won’t pit, chip, or turn green—no matter the environment.

DIRECT REPLACEMENT

Designed to match the 3-screw pattern used by standard water fittings. Swap out your old, crusty ports for a high-end quick connection that matches your boat's exisitng footprint.

UNIVERSAL QUICK CONNECT

Features our signature locking-cap and universal male tip. Works with standard adapters, but pairs best with our 316 SS spring female adapter for a precision, no-seize fit.

Installation & Fitment

The Swap: This fitting is designed to match the footprint of standard Perko-style water inlets. If you are replacing a factory fitting, the screw holes will align, but the internal clearance may vary depending on your boat’s original plumbing and hose clamps.

Universal Use: Can be installed anywhere on the boat or replace standard fittings with a universal quick connect, including transom flush ports, washdowns, or any onboard water inlet/outlet.

Plumbing: Choose the included 1/2" or 3/8" barb to match your boat’s internal hose diameter. Use marine-grade hose clamps (not included) for all internal connections.

Professional Recommendation: Because installation requires working with thru-hull components and internal plumbing lines, we strongly recommend installation by a certified marine technician to ensure a watertight seal and proper hose routing.

A Better Way to Connect

See how a quick swap turns any standard threaded onboard water inlet/outlet into a universal quick connect. Matches the same footprint of most standard water fittings and works with most female adapters you find at the store.

FAQs

My old fitting is "pitting" and looks terrible. Will this stop that?

Yes. Most standard fittings are chrome-plated brass; once the salt air hits the brass, it pits and turns green. Our solid 316 Stainless Steel is rust-proof through and through.

Is the screw pattern actually going to match my boat?

We used the most common 3-hole "industry standard" pattern. If you’re replacing a standard water inlet or outlet, it should be a direct swap using your existing screw holes.

I’ve had quick connects leak before. How is this different?

Cheap fittings often use a single, thin O-ring. Our design uses a double O-ring seal and locking cap to ensure an airtight connection even under high pressure.

Can I use this for a raw-water washdown?

Absolutely. While great for freshwater, the solid 316 SS construction is specifically designed to handle raw salt water without corroding or seizing over time.

Is it hard to install?

If you’re just swapping an old fitting, it’s a quick project. But since you’re dealing with the hull and water lines, we always recommend having your local mechanic handle it to be safe.
