Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.


Copper Item Pipes Mod
Overview
Copper Item Pipes adds functionality to all variants of copper grates, turning them into a simple item transport system. The pipes can be oxidized, waxed, or any state of copper without affecting functionality.
Crafting
- Recipe: Vanilla's 4 Copper Blocks in a star (No changes here).
- All copper block variants (including waxed and oxidized) are accepted.

How It Works
- Item Input
- Only hoppers can insert items into the copper grates/pipes.
- Droppers and dispensers cannot push items into these pipes.
- Item Throughput
- Transfers full stacks at a time (unlike hoppers, which transfer one item at a time).
- Visual Transfer
- Items are visibly moved through the grates.
- If you break a grate with an item inside, that item will drop.
- Splitting Paths
- If the pipe branches in multiple directions, the system picks one available path and ignores the rest. This means you can have backup branch paths.
- When items are transported, they will try to store into touching containers unless the grate is waterlogged.
- If no container has space, the items remain in the grate until space is available.
- Item Extraction
- Place a hopper underneath a copper grate to pull items out of it.
- Waterlogged Grates
- Pipes also work while waterlogged. However items in waterlogged pipes will prioitize transport over depositing.
Use Cases
- Build compact item transport systems.
- Control item depositing with waterlogged pipes.
- No need to worry about copper oxidation states.
Enjoy the Copper Item Pipes Mod for streamlined item transport in your Minecraft world!
