# Ingredients and components

The leafia:ff_pipe_selection predicate and Cursed item components.

## The `leafia:ff_pipe_selection` predicate

The value is `{}`. The predicate matches an item without `hbm:fluid_content`, or whose fluid content has amount 0 and pressure 0, and [claims](https://movblock.mov/ntm-next/wiki/ingredients-and-components.md#changed-component-state) `hbm:fluid_content`. Use it in the `predicates` of an `hbm:matchers` ingredient or a vanilla item predicate. Cursed special-pipe, pump, filter and converter recipes use it.
