Description
The Blu-Sub UNF Sealing Plug (Blank) is a pressure-rated plug designed to seal unused UNF-threaded ports on underwater enclosures. Available in multiple sizes and material options (black anodized aluminum or stainless steel), each plug includes an O-ring, nut, and washer to maintain watertight integrity at depths up to 1,000 meters. These plugs are especially useful when reserving Subconn-style ports for future expansion.
This product serves a similar function to the Metric Sealing Plug (Blank), which is compatible with standard metric thread sizes (e.g., M8, M10, M14). Both options allow builders to securely block off unused penetrator holes and protect internal electronics in modular subsea builds.
