The LARSEN SUPPLY CO., INC. 2238086 is a 4-piece aerator key assortment designed for removing and installing faucet aerators during plumbing service and repair. The kit includes multiple key styles to accommodate a range of common aerator configurations, making it a practical addition to any plumber's or service technician's toolkit. At 0.65 pounds, the assortment is lightweight and easy to carry to the job. This type of tool is used when a standard wrench or pliers cannot engage a recessed or cache-style aerator housing without causing damage to the finish or threads.
Aerator key assortments are used in residential and light commercial plumbing applications wherever faucet aerators require routine cleaning, replacement, or flow-rate adjustment. The assortment format means a single technician can address multiple aerator sizes and styles without carrying separate individual keys for each faucet manufacturer's specification. This is particularly useful on service calls involving multiple fixture types or when working in facilities with mixed faucet brands.
Designed as a general-purpose replacement and service tool compatible with a range of residential and light commercial faucet aerators requiring key-style removal tools.
Aerator keys are used by licensed plumbers and qualified service technicians during faucet maintenance. Shut off water supply to the fixture before removing the aerator to avoid uncontrolled discharge. Select the correct key size from the assortment before applying torque to avoid stripping the aerator housing. Work referenced to applicable plumbing codes such as the IPC where flow-rate or device specifications may apply.
