Detail 01
Hydraulic (oil between two plies)
The oil layer kills overtones at the source, so toms sound short and thick with almost no ring.

Independent shopping perspective
The Korena take
Three-ply Evans tom head pack in 12/13/16, with oil between plies for damping. For drummers who want short, fat toms without adding gels or tape.
Strong match
Who this is for
- Studio tracking where long tom ring fights the mix
- Loud stages where toms need to cut without sustain
- Replacing a full worn tom set in one purchase
Consider the trade-offs
When to look elsewhere
- Drummers who want open, singing toms with long decay
- Kits with non-standard tom sizes outside 12/13/16
- Anyone needing a matching snare or bass head here
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
Glass (clear) film
Brighter attack and more stick definition than a coated version of the same head.
Detail 03
Two-ply construction
Thicker and more durable than single-ply, at the cost of sensitivity to light playing.
Detail 04
Standard 12/13/16 pack
Covers a common five-piece layout with two rack toms and one floor tom.
Detail 05
Batter heads only
These go on the top, playing side. Bottom resonant heads are a separate purchase.
Final check
Know before you order
- 01Measure your tom shells; sizes must match exactly, not approximately
- 02No bass drum or snare head included in this pack
- 03Expect to retune lower than usual — hydraulics respond best at low tension
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Do these fit a 10/12/14 kit?
No. This pack is 12, 13, and 16 inches. Head sizes must match your shell diameters exactly, so measure the shell before ordering.
02Are these top or bottom heads?
Top, playing-side batter heads. Your resonant bottom heads stay as they are unless you replace them separately.
03Will I still need moongel or tape?
Usually not. The oil layer already handles damping, and adding more on top tends to choke the tom completely.
04How do these compare to clear two-ply heads without oil?
Much drier. A standard two-ply head still rings and projects; the oil layer here cuts sustain far shorter.
