For a 1/4-18 male NPT plug, this one matches that thread size and it has a hex head so you can tighten it with a wrench.

Hydraulic systems are one of the primary applications it's rated for, along with grease, refrigeration, and instrumentation lines. The 1/4-18 male NPT thread gives you a secure, accurate connection, and the brass construction holds up well across those uses. Fuel and gas applications are also possible but those require a special order.
