RV Battery Watering System For 3x12v With Gravity Tank 4D-8D

This RV Battery Watering Systems is specifically designed for use with your RV battery bank using 3x 12 volt batteries.

This specific battery watering system includes 18x – VB-TB5 valves, end caps, T-connectors, gravity fill tank, and ample tubing to connect all the batteries in your application to allow for a one point watering system.

This kit is great for Boats and RVs with 3x 4D or 8D 12-volt batteries with 3/4″ cell cap holes (Push in design).

Any Battery Watering system is designed to give you a system that allows for quick and easy maintenance of your Lead acid battery bank. It is accomplished by replacing the battery’s existing vent caps with valves that are interconnected with tubing, allowing the user to fill all cells of the battery bank from a single point. Quick connect connectors – Snap on/snap off water connections turn the timely task of watering batteries into a quick, simple task taking seconds or minutes, not hours! Each valve independently shuts off water flow to the cell when the proper electrolyte level is reached, allowing the batteries to be filled perfectly every time without having to look at the batteries.

Tubing Barbs

The tubing barbs eliminate the need for clamps, and they are angled to make installation easy in tight configurations.


The z-Lock feature integrates the tee piece with the valve for added strength.

Quick Look Indicator

This unique indicator eye is visible from the top and side. It confirms proper operation of the valve.

Low Profile Design

The unique valve design reduces the risk of damage from battery cables.

Clip-in Base

Installation is fast and easy: Gently push the valve into the vent well to install. No twisting is necessary to lock the valve in place.

Solid One Piece Float

Acid, temperature and impact resistant float is solidly constructed and cannot absorb water.

Spark Arrestor

The spark arrestor prevents flames or sparks from entering through the battery vent opening.
