Heavy-duty through-panel connector featuring dual sealing mechanism - metal thread engagement for primary sealing and replaceable O-ring for secondary protection. Electroless nickel plating provides corrosion resistance in humid environments. Precision-machined threads ensure leak-free connections in high-vibration applications.

Installation protocol:
Always use two wrenches during installation - one to hold the stationary hex
and another to tighten the threaded end. Apply pipe sealant only on male threads,
avoiding contact with O-ring surfaces. Perform pressure test at 1.8x working
pressure after installation.
