Marine Plumbing Supplies for Every Boat

Whether you're doing a full plumbing build or replacing a worn fitting, having the right parts on hand makes all the difference. Our marine plumbing supplies are built to handle the heat, pressure, and corrosion that come with life on the water.

Built for Saltwater. Built to Last.

Regular plumbing hardware wasn't designed for a marine environment. Saltwater, UV exposure, and constant vibration break down lesser components fast. That's why the fittings, valves, and hardware we carry are selected specifically for boat use. You get parts that hold up to real conditions, not parts that fail when you need them most.

Everything You Need to Get the Job Done

From insert fittings to shut-off valves to t-bolts and beyond, we stock the marine plumbing components boaters and boat builders actually need. Whether you're running new hose lines, replacing an old fitting, or tightening up a connection that's been giving you trouble, you'll find what you're looking for right here.

No hunting through a hardware store for parts that "might work." These are purpose-built marine components, sourced and stocked with boaters in mind.

How to Choose the Right Marine Plumbing Fitting

Boat plumbing isn't one-size-fits-all. Before you order, it helps to know:

  • Hose diameter: Match your fitting to the inside diameter of your hose for a tight, leak-free connection.
  • Material: Look for corrosion-resistant materials like stainless steel or PVC, especially if you're in a saltwater environment.
  • Application: Freshwater washdown systems, bilge lines, livewell setups, and raw water intake all have different requirements. Make sure you're using the right fitting for the job.
  • Clamp compatibility: If you're using t-bolt clamps, confirm sizing against your hose and fitting before installing.
