Sealing Plugs

Sealing plugs are used to close unused threaded holes in subsea housings and underwater systems, such as tapped expansion or mounting holes. Available in common metric and imperial threads including M6, M16 and 7/16 UNF, these plugs provide a reliable pressure-tight seal to maintain enclosure integrity. Manufactured from corrosion-resistant materials and designed for marine environments, they prevent water ingress and protect internal components when connector or mounting ports are not in use.
