Blu-Sub Sealing Plugs are designed to close unused penetrator ports and maintain full watertight integrity in subsea systems. Available in both metric (M6–M16) and UNF thread formats, these plugs are precision-machined from anodized aluminum or stainless steel and supplied with O-rings and locking hardware for reliable sealing. They are depth-rated to 1,000 m and ensure long-term protection against pressure, moisture, and debris. Ideal for modular builds, spare ports, or reserving connections for future expansion, sealing plugs are an essential accessory for protecting sensitive electronics inside ROVs, AUVs, and custom underwater enclosures.
