4E- Metric Male O-ring Plug
The 4E- Metric Male O-ring Plug is a precision-machined hydraulic fitting with an integrated O-ring groove for leak-tight sealing in metric threaded ports. Made from carbon steel with zinc-nickel plating (Cr6+ free), this fitting meets the corrosion resistance and durability requirements of fluid power systems. The plug is designed for repeated assembly and disassembly in hydraulic pump, valve, and cylinder applications, ensuring consistent performance under pressure fluctuations typical in industrial machinery and mobile equipment.
Carbon steel substrates provide the strength needed for high-pressure hydraulic circuits, while the zinc-nickel coating offers superior protection against rust and wear compared to standard zinc plating. The O-ring, typically made from nitrile rubber or FKM for chemical compatibility, ensures a reliable seal across a wide temperature range. Standard metric thread sizes for this series include M12x1.5, M16x1.5, and M22x1.5, with typical pressure ratings up to 400 bar depending on the port and system configuration.
This fitting is a staple in MRO and OEM supply chains, where it is sourced in bulk for distribution to maintenance teams and equipment manufacturers. Buyers typically include hydraulic system integrators, industrial machinery producers, and maintenance service providers who require consistent sealing performance in demanding environments. Bulk packaging options often include 100 or 500 pieces per box, with custom machining available for non-standard thread sizes or material specifications upon request.
