How to say "nozzle" in Japanese

Choosing the right word

ノズルCommon
nounThe direct loanword for a nozzle as a physical part: a spray, hose, or machine fitting that directs liquid or gas. This is usually the word you want for the device itself.
先さきJLPT N5approx.Common
nounA general word for the point or tip of something. Its 'nozzle' gloss covers cases where you mean the end of a tube or spout rather than the device; for the device itself, ノズル is the word to use.
鉛筆えんぴつの先さきが丸まるくなった。↗
The point of the pencil has become dull.
火口ひぐちCommon
nounLiterally the mouth where fire comes out; its 'nozzle' sense applies to burners, such as a gas stove or burner head. Outside fire- or burner-related contexts it is not the ordinary way to say 'nozzle'.

Use 「ノズル」 for the device itself (spray, hose, machine), 先 for the tip or pointed end of something, and 火口 mainly for burner mouths where gas or flame comes out.
