Neoperl Tom Thumb PCA Cache Aerator – 1.5 GPM M16.5x1, Honeycomb Filter, 2-Pack with Install Key

Upgrade your faucet with Neoperl Tom Thumb PCA Cache Aerator

Designed to tuck into spouts built without a metal housing, this hidden aerator delivers a clean, minimalist look while producing a balanced, fully aerated water stream. The compact Tom Thumb design fits where some traditional housings can’t reach, giving your faucet a streamlined profile without sacrificing performance.

Each unit features a pressure compensating flow controller to help maintain a steady feel as water pressure changes, and a honeycomb filter screen that contributes to a soft, white stream that’s pleasant to the touch and less prone to splashing. The result is a dependable, smooth deliverable flow that works well for everyday tasks from quick handwashing to careful dish prep.
