Flojet 18599-000A Adapter
The Flojet 18599-000A is a genuine replacement adapter for Flojet pumps. An adapter is the piece that lets two components with different connections work together — joining a port to a line, a pump to a fitting, or one thread or tube standard to another.
Small transition parts like this are the ones most often improvised, and improvising them is where a great deal of trouble on a water system starts. A stack of two or three hardware-store reducers does the job geometrically while introducing several extra sealed joints, a longer assembly that levers on whatever it is screwed into, and at least one interface hidden inside the stack where nobody can inspect it. The manufacturer’s own adapter does the same job in one component, with one seal and the correct dimensions throughout.
Because adapters are specific to the components they join, the part number matters more than the general description. Confirm this number against the parts breakdown for your pump before ordering, and if the label on your pump is no longer readable, send us what you can make out and the CLR Marine team will work through it with you.

Frequently Asked Questions
Q: Why not just use hardware store reducers?
They work geometrically and fail practically. Each added joint is another seal to make correctly, and the one in the middle of the stack is the one you cannot see or reach once it is assembled.
Q: How much does a long adapter stack actually matter?
More than expected on a plastic port. A long assembly acts as a lever, so any knock against the plumbing is multiplied at the threads it is screwed into.
Q: How do I confirm this is the adapter I need?
Match the part number against the parts breakdown for your pump model. Dimensions on transition parts vary in ways that are not obvious from a photograph.
Q: What if my pump label is unreadable?
Send us whatever is still legible, along with a photograph of the pump and the connection you are trying to make, and we will identify it with you.
Not sure this is the right part? Send us a Picture of the pump plate on your pump and the CLR Marine team will confirm the correct part before you order.
