Gooseneck Flow Control Kit 1.6 GPM

The Chicago Faucet Company kit provides a laminar flow outlet rated at 1.6 GPM for single-hole bathroom faucets. It is intended for commercial or institutional projects that require a gooseneck spout with controlled water delivery. The kit includes the laminar insert assembly for a clear, non-aerated stream.

Laminar Insert Assembly Upgrade

This kit replaces a standard aerator or worn outlet with a laminar insert flowing at 1.5 gpm. The change is worth it when local codes or facility specifications call for a laminar stream rather than an aerated one. Buyers who need a higher flow rate or an aerated spray pattern should select a different outlet type.

Single-Hole Installation Notes

Installation fits single-hole faucet bodies using the existing mounting hardware. Common issues include thread mismatch on older faucet bodies and debris blocking the laminar insert after installation. Flushing supply lines before fitting the insert reduces the risk of clogging.

Questions about this item

Does the 50-042KJKABNF kit fit a standard single-hole sink cutout?

Yes, the kit is designed for single-hole faucet installations and includes the gooseneck spout and laminar flow control components needed for that mounting style.

What is the most common installation mistake with the laminar insert assembly?

Installers sometimes omit the laminar insert or seat it unevenly, which changes the outlet pattern and can reduce the 1.5 gpm flow rate.

How often should the laminar insert be replaced to maintain the 1.5 gpm flow rate?

Replace the laminar insert when mineral buildup visibly restricts the outlet or flow drops below the rated 1.5 gpm; no fixed interval applies.
