KOHLER GENUINE PART 1104957 INSERT, LAMINAR, 1.5GPM, LARGE

Experience poor flow from my Kohler faucet. Got this replacement aerator and voila, problem fixed. Easy to replace and appears to be high quality. Original survived 10 years, hope this does as well.

easy to replace and works perfect for our Kohler faucet. crossed ref the current PN to this.

This works great and feels like vastly more water than an equivalent aerator, which makes cleaning dishes and hands more effective. I recently purchased a six pack of non-branded "laminar flow 1.5gpm regulators" that were actually aerators (tons of bubbles, splashing and noise but feels like less effective water at the same gpm when washing dishes out hands at the sink). Unlike those, this is the real deal: laminar flow with no bubbles or splashing, and it genuinely feels and works like a higher flow rate, so helps conserve water. I measured and it is almost exactly 1.5 gpm even with our high pressure water supply.

The OEM dispels low GPM (like 1.5 GPM), for water saving. Some replacements allow 5 GPM, which flows better. The special wrench needed to replace the aerators is critical.
