Trident Reagent Needle Guides

Set of 3 Neptune Systems Trident Reagent Needle Guides. 

Installing these will help keep the needles for the reagent bottles straight and prevent them from turning on their side. This will help reduce the amount of false readings when the reagent is low. It will also prevent the needle from drawing up any air.

Installation instructions:
 1. Unscrew the cap of the reagent bottle
 2. Place the guide into the bottle
 3. Insert the needle through the center hole of the guide and screw on the bottle cap.

W: 1.6" H: 1"

Each guide is made with 100% reef safe PETG high-quality filament.
