Larsen Supply 09-1605NL Aerator Adapter Chicago Faucet

Product Description

The Larsen Supply Co. 09-1605NL is a chrome plated aerator adapter designed to convert thread sizes on Chicago faucets that feature an outside male thread. It accepts a 13/16 inch x 24 female thread on one end and steps up to a 55/64 inch x 27 male thread on the other, allowing a standard aerator to be installed where thread sizing would otherwise be incompatible. This adapter is No Lead compliant under Vermont and California AB-1953 regulations, making it suitable for potable water applications in states with strict lead content requirements. Plumbers and fixture installers working on commercial or institutional faucets will encounter this fitting when servicing Chicago Faucet brand equipment.

This adapter is used in residential and commercial plumbing applications where Chicago Faucet equipment is installed, particularly in settings such as schools, hospitals, and commercial kitchens where Chicago Faucet products are common. It is a carded product packaged in units of six, making it practical for service vans and shop stock. The adapter is appropriate for any plumber performing aerator replacement or faucet maintenance on Chicago Faucet models equipped with outside male threads.

Compatibility

Designed for use with Chicago Faucet models that feature an outside male thread requiring a 13/16 inch x 24 thread connection at the aerator seat.

Installation Notes

Installation is performed by a licensed plumber or qualified faucet service technician. Shut off the water supply to the faucet before beginning work. Hand-tighten the adapter first, then use an aerator wrench or appropriately sized pliers with a cloth or tape wrap to avoid marring the chrome finish. Do not overtighten, as excess force can crack the adapter or damage faucet threads.
