It allows you to downsize a fluid, air, or gas line from 1/4″ to 1/8″ NPT, commonly used in truck air brake lines, fuel systems, and industrial plumbing. Replace one when threads become damaged, you need to adapt mismatched fittings, or when building custom hose assemblies. These are typically made of brass or steel for corrosion resistance and reliable sealing.
