Detail 01
Hydraulic (oil between two plies)
The oil damps the head itself, so overtones die fast and the note drops in pitch.

EvansHydraulic Glass Drum Head - 12 IN
1/3
Independent shopping perspective
The Korena take
12-inch two-ply tom head with an oil layer between plies. Buy it if you want short, controlled tom notes without taping.
Strong match
Who this is for
- Rack toms that ring too long in small rooms
- Drummers who tape heads to kill overtones
- Studio work where mics pick up every overtone
Consider the trade-offs
When to look elsewhere
- Drummers wanting open, sustaining jazz toms
- Anyone chasing maximum stick-to-head sensitivity
- Snare or kick use — this is a tom size
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Two-ply construction
Thicker and more durable than single-ply, at the cost of sustain and high-end attack.
Detail 03
Glass finish
Clear film, so no coating to wear off and slightly more attack than a coated head.
Detail 04
12 inch
Head size must match your drum's shell diameter, not the depth. A 12-inch tom takes this.
Detail 05
Batter head
This is the top head you strike. The bottom resonant head is a separate purchase.
Final check
Know before you order
- 01Sold as one head, not a set — a full kit needs several
- 02Measure the drum's shell diameter, not the old head's hoop
- 03Budget a drum key and a few minutes for even tensioning
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit a 12-inch tom?
Yes, as long as your tom's shell measures 12 inches across. Head sizes are named for shell diameter, not the outer hoop.
02Can I use this as a snare head?
It's sold as a tom head. On a snare it would heavily choke response and sensitivity, so it's the wrong tool for that job.
03Does this come with a bottom head?
No. This is a single batter head. Resonant heads are bought separately.
04Do I still need moongel or tape?
Usually not. The oil layer does the damping, which is the point of a hydraulic head.
