Product Questions & Answers (2)

Question by: Gene C on Jun 11, 2025, 2:10 PM
got a port that’s 1-11-1/2 NPTF male, is this the right hex plug to cap it off?
Answer by: Customer Support on Jun 13, 2025, 8:58 AM
For a 1-11-1/2 male NPTF thread, this part matches that thread size and type and is a straight hex plug style adapter in the Danfoss 2082 series.
Question by: Diane W on Dec 14, 2025, 7:49 PM
What all can this plug be used on, grease fittings, hydraulic lines, or just one or the other?
Answer by: Customer Support on Dec 16, 2025, 4:50 PM
Grease systems, instrumentation lines, and most hydraulic systems are all fair game for this plug. It's a 1-inch 11-1/2 male NPT hex plug from Eaton Aeroquip's 2082 series, so it covers a pretty wide range of applications rather than being locked into just one use case.
