The 5409X04 Hydraulic Hex Socket Pipe Plug (1/4") is a high-pressure pipe plug designed to securely seal hydraulic ports, manifolds, and fluid system openings. Constructed from durable carbon steel with CR6-free clear zinc trivalent plating, it provides reliable corrosion resistance while meeting RoHS compliance requirements. The internal hex socket design allows quick installation with an Allen wrench, while the 1/4"-18 MNPT thread ensures a tight, dependable seal in hydraulic and fluid power systems. Rated for up to 6000 PSI, this compact plug is built to keep hydraulic systems sealed and running clean—because hydraulic oil belongs inside the system, not decorating the shop floor.
