got a 1/4-18 npt port i need to cap off, is this the right plug?

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.
Question by: Harvey A on Oct 11, 2025, 9:58 PM
does this plug work for hydraulic systems or is it just for like air and water lines?
Answer by: Customer Support on Oct 13, 2025, 6:34 AM
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.
