vacuum ports

Self-sealing vacuum ports in combination with a Deck Purge Box ease the procedure to open and close pressure housings and eliminate any moisture inside the enclosure.


Instrument housings usually incorporate a vacuum port to facilitate repeated sealing and unsealing actions.

Nautilus Marine Service offers manually locking and self-locking vacuum ports.

For both types two versions are available. Manually locking vacuum ports can be supplied with a single or double o-ring seal and self-locking vacuum ports with either 7/16” or 5mm shaft diameter.

Self-locking vacuum ports together with the VITROVEX® Deck Purge Box is an innovative locking and purge concept and provide immediate improvement over traditional, manually locking vacuum ports by dynamically removing moisture from the entrained air inside an instrument housing.
