STICKY PISTON
Like a regular piston but pulls the attached block back when retracting. Essential for doors, drawbridges, and any mechanism that needs blocks to return to their original position.

What Sticky Piston costs you on the crafting grid, exactly
To craft Sticky Piston you place 1 Piston and 1 Slime Ball in the shape below, which fills a 1x2 corner of the grid. 2 items in, one Sticky Piston out.

What the Sticky Piston is, and what it does for you
Like a regular piston but pulls the attached block back when retracting. Essential for doors, drawbridges, and any mechanism that needs blocks to return to their original position.
As a mechanical component it converts a redstone signal into physical action rather than passing the signal onward. It is the piston that brings blocks back, making it essential for doors, drawbridges, and anything that must reset to its start position.
Sticky Piston has been in the game since Beta 1.7, and the numbers on this page are the Java Edition 26.2 ones.
Inside the Sticky Piston: what the signal actually does
On the input side, any redstone signal (including quasi-connectivity in Java). It returns no redstone signal of its own, its effect is mechanical output only.
It pushes like a normal piston but grips the front block and pulls it back on retraction. The same 12-block limit and 3-game-tick retraction apply. If it is given a pulse shorter than the retraction time (a so-called 0-tick or 1-tick pulse) it will push but fail to pull the block back, dropping it.
Timing-wise, factor in 0 ticks to extend, 3 game ticks to retract when you wire it into a sequenced circuit.
These are the modes you can put the Sticky Piston into, and each one changes what comes out: extended (block pushed) and retracted (block pulled back).
Setting up the Sticky Piston the right way
- 1Craft the Sticky Piston: 1 Piston + 1 Slime Ball → 1 Sticky Piston.
- 2Set the Sticky Piston down facing the way the signal has to travel, on a block that will actually hold it in place, and leave room in front of it for the movement.
- 3Feed it a redstone pulse or signal from a lever, button, or circuit; it will perform its action and ignore further power until the input changes.
- 4Before it goes anywhere near a real build, run the Sticky Piston on its own a few times over and check every result against the timing figures listed above this step.
Jobs the Sticky Piston does well
- ▸Hidden piston doors
- ▸Block swappers
- ▸Secret passages
- ▸Flying machines
- ▸Drawbridges
Tips & common mistakes
- !Does not pull block if given a 1-tick pulse (0-tick)
- !Same 12-block push limit
- !Cannot pull tile entities (chests, furnaces)
- !Feed it a pulse that is too short and it 'drops' its block instead of retracting it, keep input pulses at 2 ticks or longer for reliable pulling.
Sticky Piston, frequently asked questions

What do redstoners actually build with the Sticky Piston in Minecraft?
The Sticky Piston is most often used for hidden piston doors, block swappers, secret passages, and flying machines. As a mechanical component it converts a redstone signal into physical action rather than passing the signal onward.

How far does the Sticky Piston push a signal?
The Sticky Piston does not output a redstone signal of its own; its result is none (mechanical output only). Its purpose is physical action, not signal generation.

What does a Sticky Piston cost to make?
1 Piston + 1 Slime Ball → 1 Sticky Piston. It was introduced in Beta 1.7.

Does the Sticky Piston add any delay to a circuit?
Yes, 0 ticks to extend, 3 game ticks to retract. Account for that timing when chaining it with other components, especially in clocks and fast doors.
Components that connect to Sticky Piston
Sticky Piston does not stand on its own. 6 other component pages are tied to it:
Piston, 1 of these goes into Sticky Piston
TNT, one of the 12 in the same group
Redstone Lamp, grouped with Sticky Piston, 12 of them in total
Bell, sits in the same group of 12 as Sticky Piston
Crafter, another of the 12 components in this group
Slime Block, grouped with Sticky Piston, 12 of them in total
Mining Sticky Piston: how hard, how bright and how tough
Bring a pickaxe: Sticky Piston has a hardness of 1.5.
Blast resistance matches at 1.5, so a creeper next to Sticky Piston takes it with him. It emits no light of its own, so it will not stop a mob spawning next to it.
| Sticky Piston | Java Edition value |
|---|---|
| Sticky Piston hardness | 1.5 |
| Sticky Piston blast resistance | 1.5 |
| Fastest tool on Sticky Piston | pickaxe |
| Light out of Sticky Piston | 0 |
