What does manifolder mean?
A manifolder is chiefly a branching component through which a fluid or gas is distributed or collected. Its best-known application is the exhaust manifolder of an internal-combustion engine, which gathers exhaust gases from the cylinders, and the intake manifolder, which delivers the air-and-fuel mixture to them. Similar devices distribute oil, refrigerant, hydraulic fluid, or compressed air in mechanical and industrial systems. The term can also denote an older device for making several copies of a document, though this sense is now uncommon. The word is more precise than the general noun manifold because it emphasizes a component that divides one passage into several branches or unites several passages into one. Outside engineering and related technical fields, it is chiefly encountered in discussions of automobiles, machinery, and historical office equipment. Its unusual name is memorable because it literally suggests one passage multiplied into many.
nounA pipe, fitting, or chamber with several branches or outlets, used to distribute or collect a fluid or gas, especially in an engine, plumbing system, or hydraulic installation. In older office and printing contexts, a manifolder is a device designed to produce multiple copies of a document.
- A pipe, fitting, or chamber with several branches or outlets, used to distribute or collect a fluid or gas, as in exhaust, intake, hydraulic, and pneumatic systems.
- A device designed to produce multiple copies of a document.
"The mechanic replaced the cracked exhaust manifolder before the engine began misfiring."
"The mechanic replaced a cracked exhaust manifolder before the engine began misfiring."
"The typist fed the master copy into the manifolder, producing several duplicate forms."
Manifolder is a countable noun; plural manifolders is standard when referring to multiple branching components or devices.
"The factory installed new hydraulic manifolders throughout the production line."
A manifolder is plumbing’s fork in the road—except every branch carries the same fluid.

Etymology of manifolder
Manifolder was formed in English by adding the suffix -er to manifold, adapting the word into the name of a concrete device. Manifold continues Old English manigfeald, associated with manig, meaning “many,” and feald, meaning “fold”; manyfold preserves the same numerical idea in a parallel compound. The name therefore reflects multiplication: a single passage is divided into many branches or several passages are gathered into one.
How manifolder is actually used
This is primarily a technical noun used in engineering, automotive maintenance, plumbing, and fluid control. It is less common in general speech than the adjective manifold or the attributive phrase manifold pipe, although it is a useful specific term for a branching device.
Easily confused with manifolder
Manifolder specifically names a branching component or device, whereas manifold can also mean numerous or varied and is the more usual attributive form, as in manifold pipe.
