Detail 01
Oil layer between plies
The oil damps the head as it vibrates. Sustain drops sharply, giving a thick, controlled thud.

EvansHydraulic Glass Drum Head - 18 IN
1/3
Independent shopping perspective
The Korena take
An 18-inch clear Hydraulic tom head with an oil layer between two plies. For drummers who want a short, fat tom sound with no ring.
Strong match
Who this is for
- 18" floor toms on a rock or metal kit
- Players who tape and muffle heads and want to stop
- Deep, punchy tom fills that die quickly
Consider the trade-offs
When to look elsewhere
- Jazz and orchestral players needing open sustain
- Anyone wanting bright, cutting tom attack
- Drummers who tune high and want the tom to sing
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
Clear film
Brighter and more attack than coated. The oil pulls the tone back down, so it lands warm overall.
Detail 03
Glass version
The clear Hydraulic. Same oil damping as the coated, with a bit more stick definition.
Detail 04
18-inch batter
Fits an 18" floor tom shell. Big diameter means low pitch and a long, slow response.
Detail 05
Two-ply thickness
Takes hard hitting and lasts longer than single-ply, at the cost of sensitivity to quiet playing.
Final check
Know before you order
- 01One head only — you'll want the resonant side handled separately
- 02Tune it lower than you think; hydraulics don't like high tension
- 03Confirm your floor tom is 18", as 16" is the more common size
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this work on an 18" bass drum?
Physically it fits, but it's built as a tom batter. Bass drum heads are made for beater impact and mounted muffling.
02Do I still need moongel?
Usually not. The oil layer does the damping, which is the point of the head.
03How does it compare to a coated Hydraulic?
Same oil damping, more stick attack and brightness. The coated version is a touch warmer and drier.
04Is it durable for hard hitters?
Yes. Two plies plus the oil layer make it one of the more dent-resistant tom heads.
