Hoses & Fittings

Hoses, Fittings, Valves, Thru-Hulls & Plumbing Connections

Shop hoses and fittings for onboard plumbing, freshwater, drains, showers, sanitation, thru-hulls, valves, adapters, clamps, pipe fittings, and hose connection repairs. Match every part by hose inside diameter, thread type, material, system, pressure, temperature, and installation location.

Shop Hoses & Fittings Browse Categories Ask Parts Desk
Measure Before Ordering

Confirm hose ID, fitting size, thread standard, barb size, material, bend radius, valve type, and whether the part is used above or below the waterline.

Search Hose Adapters

Find the Right Connection

Search by Hose Size, Fitting Type, Thread, Valve, Material, or Part Number

Plumbing parts can look similar while using different thread standards, barb sizes, materials, and installation ratings. Use the stamped part number, measured hose ID, fitting size, and system type whenever possible.

Fitment

Size the Hose, Then Match the Fitting

Measure hose inside diameter, fitting barb outside diameter, thread size, thread standard, clamp range, and available space. Flexible hose, rigid pipe, valves, elbows, and adapters all need enough room for a smooth run without kinks, chafe, or strain.

Material

Choose Material by Location and System

Below-waterline hardware, deck drains, freshwater lines, sanitation systems, and shower fittings can call for different materials. Consider bronze, stainless steel, composite, PVC, plastic, brass, and reinforced hose based on the system and installation point.

Bronze ValvesStainless FittingsComposite Thru-Hulls
ID

Hose Inside Diameter

Use inside diameter for hose selection and match it to the fitting barb, clamp range, and system flow requirement.

THREAD

Thread Standard

BSPT, NPT, NPS, pipe size, and metric references are not interchangeable. Match thread type before forcing a fitting.

RATING

Use the Right Rating

Check pressure, temperature, fuel, sanitation, freshwater, and below-waterline suitability before installation.

FAQ

Choosing Hoses, Fittings & Plumbing Parts

How do I choose the correct hose fitting?

Start with hose inside diameter, fitting barb size, thread type, material, system, and whether the connection is above or below the waterline. If replacing an old part, use the stamped part number or the exact measurements.

Are all valves suitable below the waterline?

No. Below-waterline installations need the correct material, strength, thread compatibility, and installation rating. Do not assume a plastic, PVC, or general shutoff valve is right for every below-waterline job.

What is the difference between a check valve and a non-return valve?

Both are used to reduce reverse flow. Product names vary by manufacturer, so choose by inlet size, outlet size, valve style, flow direction, service location, and system compatibility.

When should hose clamps be replaced?

Replace clamps that are rusted, stripped, cracked, distorted, loose, or no longer hold tension. Use the correct clamp range and material for the hose size and installation environment.

Ready to Repair or Build the Connection?

Use the old part number when possible. If not, measure the hose, fitting, thread, clamp range, and installation space before choosing a replacement.
