Question by: Tony R on Jan 21, 2026, 6:49 PM
Will this plug hold up if I'm using it in a hydraulic system running at high pressure?

This stainless steel plug is designed to provide a secure seal in hydraulic systems, helping to prevent fluid leakage even under pressure.
Question by: Dustin E on Jul 15, 2025, 3:52 PM
Got a port I need to block off on a hydraulic manifold, will a 9/16-18 JIC plug get that job done, or am I looking at the wrong fitting?
Answer by: Customer Support on Jul 17, 2025, 11:11 AM
For a 9/16-18 JIC port, this is exactly what you need. The male JIC 37-degree flare thread matches that port type, and the stainless steel construction holds up well in hydraulic systems where you need a clean, leak-free seal. At just 0.84 inches long, it fits in tighter manifold setups without much fuss.
