Is your Delta bathroom faucet splashing or the water flow seems off? This OEM Delta RP51345 aerator is likely the replacement part you need. It's a 1.5 gallons per minute (GPM) aerator with M16.5 x 1 male threads, which is a common size for many Delta Lahara series and other models. The aerator mixes air with the water to give you a smooth, splash-free stream while conserving water. It has a blue identification ring. To install, just unscrew the old aerator from the faucet spout (might need pliers if it's stuck) and screw this one in hand-tight. Fixes flow issues and restores your faucet's performance.
