sulkeamat

Sulkeamat is a Finnish term used to refer to closures or sealing elements that stop or isolate a flow or space. In its singular form sulkeama denotes a sealing device or closing mechanism, such as a valve shut-off, a gasket, or a sealing surface. The plural sulkeamat describes multiple such closures. The term appears across several technical fields, including mechanical engineering, plumbing, and process technology, where reliable sealing and the ability to isolate sections of a system are essential.

In valve technology, the sulkeama is the component that completes the shut-off and forms a leak-tight seal when engaged, whether by manual, pneumatic, or electric actuation. In piping and HVAC installations, sulkeamat may refer to gaskets, packing, or flanges that contribute to a seal and prevent leakage. The word can also be used more broadly to describe any means of closing or restricting access, such as safety procedures or data-handling barriers that require containment or isolation.

Etymologically, sulkeamat derives from the Finnish verb sulkea, meaning “to close,” with the nominalizing suffix -ma and the plural ending -t. The term is primarily used in Finnish-language technical documentation; in English-language contexts, the corresponding terms are seals, closures, shut-off devices, or valves, chosen to fit the specific application.
