Keep your Aquatica AT2i underwater housing watertight with this O-Ring Maintenance Kit. For complete camera compatibility information, please see below. The kit contains a full set of replacement O-rings for the enclosure, i.e., one large main seal and two smaller seals for the port and extension, along with a container of silicone lubricant to keep the rings from drying out and cracking.

Aquatica's neoprene O-rings are built to withstand extreme temperatures and are highly resistant to harsh solvents. After changing any O-ring, a pressure test or immersion without a camera inside the housing is mandatory. Failure to perform this test could result in serious damage to your camera and lens if the O-ring is improperly installed.
