Advanced 4C-WD Metric male plug with captive seal (ED Ring) hydraulic adapter. Engineered with parallel Metric male threads, an integrated elastomeric captive seal (ED ring), and a heavy-duty external hex head to provide rapid manifold port blanking, positive flat-face sealing, and superior blowout resistance in high-pressure industrial hydraulic systems.
The 4C-WD Series is a high-performance fluid connection component specifically engineered for blanking and dead-ending ISO 9974 / DIN 3852 standard metric manifold ports and valve blocks. Featuring a precision-machined Metric male threaded stud with an elastomeric captive ED seal ring paired with a solid external hex head, this plug guarantees effortless torque tightening, positive flat-face port seating, and zero-leak reliability under extreme dynamic pressure impulses.
With optional zinc-nickel alloy surface treatment available to significantly extend service life, this hydraulic plug ensures maximum longevity, structural safety, and leak-proof performance for heavy-duty industrial fluid power networks.
Engineered to work together with the product above.
