This valve is used for Deka batteries with the exception of the D35 and D45.

Hydrometer Port

Hydrometer readings can be taken without removing the valve from the battery. The hydrometer opening has a slider with a stop so the covering won't break or get lost.

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.

Indicator Eye

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.

Encapsulated Float

Reinforced encapsulation protects the float and eliminates interference with the moss shield.

Solid One Piece Float

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