The LARSEN SUPPLY CO., INC. 09-1657 is a universal-fit aerator hose adapter designed to connect standard faucet aerators to hose fittings in residential and light commercial plumbing applications. This adapter is sold as a carded unit and is packaged in quantities of six, making it a practical stock item for plumbing supply houses and service trucks alike. Weighing 0.66 pounds per package, it is a compact, lightweight fitting suited for quick service calls and faucet maintenance work. The FitAll design is engineered to fit most aerator hose adaptor configurations, reducing the need to stock multiple part-specific adapters.
This adapter is commonly used during faucet aerator service, hose-to-aerator connection work, and general sink maintenance in residential kitchens and bathrooms as well as light commercial settings. Plumbers and plumbing maintenance technicians install this part when converting a standard aerator thread to accept a hose fitting or when adapting mismatched thread configurations at the faucet spout. Its broad fitment range makes it a go-to option for service work where the exact faucet brand or aerator thread spec may be unknown.
Designed as a universal-fit replacement adapter compatible with most standard faucet aerator hose adaptor fittings in residential and light commercial plumbing applications.
Installation is typically performed by a licensed plumber or experienced plumbing technician. Shut off water supply to the faucet before beginning any aerator or fitting work. Hand-tighten the adapter first to confirm thread engagement, then snug with pliers using a cloth or tape wrap to protect the finish. Do not overtighten, as aerator threads are typically brass or plastic and can be damaged by excessive force.
