Name: Reducing Hose Couplings Nakajima Type
Brand: ALL-K MARINE
SKU: 330884-330885-330891

These reducing hose couplings, Nakajima type, are essential for connecting fire hoses of different diameters on cargo ships, container vessels, tankers, and offshore vessels. They enable quick and secure attachment between a larger supply hose and a smaller delivery hose, ensuring reliable water flow during firefighting or deck washing operations. Designed for rugged marine use, they solve the problem of incompatible hose connections, enhancing safety and operational efficiency on board.

The couplings are manufactured from high-grade brass, offering excellent corrosion resistance in the saline marine environment. They are available in three sizes to cover a range of hose diameter reductions, each identified by its own IMPA code (330884, 330885, 330891). These couplings meet the demands of marine firefighting systems, providing a leak-tight, durable connection that withstands high water pressure and frequent handling.
