Product Questions & Answers (3)

Question by: Denise R on Dec 9, 2025, 9:14 PM
Does this adapter work for grease systems, or is it just for hydraulic lines?
Answer by: Customer Support on Dec 10, 2025, 9:26 PM
Grease, instrumentation, and most hydraulic systems are all listed applications for this fitting. So whether you're hydraulic connections into a lube system or tying into a standard hydraulic circuit, it covers the bases. It's a steel bushing-style adapter going from 1/2-14 male NPT on the outside down to 1/8-27 female NPT on the inside, made by Eaton Aeroquip under their 2081 series.
Question by: Dwayne G on Oct 2, 2025, 12:46 PM
got a 1/2 npt port on a block and i need to run a little 1/8 npt gauge off it. is this the right bushing?
Answer by: Customer Support on Oct 4, 2025, 7:14 AM
For stepping a 1/2-14 male NPT connection down to a 1/8-27 female NPT port, that is exactly what this reducer bushing is set up to do.
Question by: Terry A on Feb 23, 2026, 9:04 PM
Just wanna make sure, this adapter will let me go from a 1/2 inch male pipe thread down to a 1/8 inch female, right?
Answer by: Customer Support on Feb 25, 2026, 4:39 PM
Yes, that's exactly what this Eaton Aeroquip adapter does. It's designed to reduce from a 1/2-14 Male NPT to a 1/8-27 Female NPT.
