Question by: Harold W on Dec 22, 2025, 6:54 AM
what thread size does this cap fit?
Answer by: Customer Support on Dec 23, 2025, 7:02 PM
3/4-14 NPT is the thread on this cap, which is the standard 3/4 inch National Pipe Thread spec. Female NPT at that size is pretty common in hydraulic and fluid line work, so it drops right onto any male 3/4-14 NPT fitting or port you need to seal off.

got a 3/4-14 female npt port i need to cap off, is this the right one?
Answer by: Customer Support on Oct 20, 2025, 6:56 AM
With a 3/4-14 female NPT cap, the fit is based on matching that same 3/4-14 thread size on the port you are closing off.

Reckon this cap will fit a standard 3/4 NPT thread? Don't wanna order the wrong thing again.
Answer by: Customer Support on Jan 15, 2026, 2:05 PM
Yeah, it's made to fit a 3/4-14 Female NPT thread, same as the product name says.
Question by: Dale Y on Feb 13, 2026, 9:39 PM
does this cap need any thread sealant or tape to seal up proper, or is it good to go as-is?
Answer by: Customer Support on Feb 15, 2026, 6:38 PM
No tape or thread sealant is required with this cap. It's built to provide an effective seal on its own when threaded onto a 3/4-14 NPT female port, which saves a step during installation and cuts down on the mess that comes with pipe dope or PTFE tape.
Question by: Bonnie H on Mar 29, 2025, 9:33 AM
What size is this cap? Just wanna make sure it fits my pipe threads.
Answer by: Customer Support on Mar 30, 2025, 5:36 PM
The cap has a 3/4-14 thread size. This should ensure a secure and precise fit for compatible pipes.
