Question by: Dean H on Aug 26, 2025, 9:32 AM
fitting's got a 1/8-27 NPT thread on it -- will that work for plugging off a port on a grease system or is it only rated for hydraulics?
Answer by: Customer Support on Aug 28, 2025, 6:45 AM
Grease systems are actually one of the listed applications for this plug, right alongside instrumentation and general hydraulic use. The 1/8-27 male NPT thread is a standard pipe thread size that shows up constantly in grease fittings, lube ports, and small hydraulic blocks, so it crosses over between those duties without any issue.
Question by: Lee G on May 22, 2025, 8:23 AM
got a port i need to cap off, is this the right kind of plug for a 1/8-27 npt hole
Answer by: Customer Support on May 24, 2025, 7:36 AM
For capping a 1/8-27 NPT port, this part matches that thread callout as a male NPT countersunk hex plug. It’s a straight pipe/plug style adapter intended to close off ports in grease, instrumentation, and most hydraulic system use.
