Quick-Connecting Fluid Couplers
Fluid couplings are
indispensable in providing connections in systems that involve the flow
of air, water, oil, or gas. Nitto Kohki couplings are distinguished by
their high quality and durability. Their safe, easy one-hand connection
and disconnection enables superior operability. Their built in automatic
open and shut valve provides high flow, easy flow control and realizes
a perfect seal. To meet diverse needs for couplings for applications in
the home as well as in the medical, biotechnology, nuclear, semiconductor
and computer fields, Nitto Kohki offers a full product line-up comprising
of 3,000 series and some 25,000 individual models.
Nitto Kohki couplers
provide quick and easy connection/disconnection of fluid lines such as
water, oil, gas, and air. They completely eliminate the inconvenience
of connecting/disconnecting conventional thread type couplings or flanges,
fluid leakage, and hose kinking, while providing quick, convenient control
and maintenance of fluid line connections.
