Everything you need to plumb a boat properly. This collection covers marine valves and hose connectors for freshwater, waste, bilge and cooling systems: non-return valves, diverter and Y-valves, hose tails, straight and elbow connectors, T-pieces, reducers and skin fittings in the common marine hose sizes.
Marine plumbing lives in a harsh environment, so every fitting we stock is chosen for corrosion resistance and reliability below the waterline and out of sight in lockers. Match the connector to your hose's internal diameter, double-clip any connection below or near the waterline, and replace suspect valves before they fail. Not sure which fitting you need? Bring the old part in store or contact us and we'll identify it.
Frequently asked questions
How do I size a hose connector?
Match the hose tail to the internal diameter of your hose - common marine sizes include 13mm, 19mm, 25mm and 38mm. The hose should push on firmly and be secured with stainless hose clips.
What does a non-return valve do on a boat?
A non-return (check) valve lets liquid flow one way only - preventing bilge water flowing back down the discharge hose, or waste and water siphoning back into the system.
Should I use one or two hose clips on marine fittings?
Any hose connection below or close to the waterline should be double-clipped with quality stainless steel clips, as a failed connection there can flood the boat.
