Detail 01
Oil between two plies
The fluid layer absorbs vibration internally, so the head self-muffles without tape, gels or muffling rings.

EvansHydraulic Glass Drum Head - 13 IN
1/3
Independent shopping perspective
The Korena take
A 13-inch two-ply tom head with oil sealed between the plies. For drummers who want a fat, short, controlled tom note with minimal ring.
Strong match
Who this is for
- Studio work where long tom sustain fights the mix
- Rock and pop players wanting a thick, punchy tom thud
- Kits that ring uncontrollably and need muffling built in
Consider the trade-offs
When to look elsewhere
- Jazz or fusion drummers wanting open, singing toms
- Players chasing bright attack and long decay
- Anyone with 12 or 14 inch toms — this fits 13 only
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 finish
Clear film, so you get more attack and a slightly brighter voice than a coated head of the same build.
Detail 03
Two-ply
Thicker and more durable than single-ply, with less sustain and a lower fundamental pitch.
Detail 04
13 inch
Typically a rack tom size. Measure the shell diameter, not the hoop, to confirm.
Detail 05
Batter side
Goes on the top. Your resonant head stays whatever it is and shapes the decay from underneath.
Final check
Know before you order
- 01One head only — no resonant head, drum key or tuning tools included
- 02Very short sustain by design; you cannot tune the muffling back out
- 03Tune it lower than a single-ply head or it can sound choked
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Why is there oil inside the head?
The thin oil layer between the two plies dissipates vibration as the head moves, killing overtones and shortening sustain without any external muffling.
02Will this fit my 13 inch tom?
Yes, if the shell measures 13 inches across. Measure the shell itself, not over the rim or hoop, since hoops add width.
03Is it too dead for live playing?
It is a controlled, short sound. Live it cuts through well and needs no muffling, but you lose the open ring some players want on stage.
04Can I use this on a snare?
On a 13 inch snare it will fit, but the oil damping kills sensitivity and ghost notes. A dedicated snare batter is a better choice.
