Neoprene Perimeter O-Ring Gasket for Seahorse 56 Case

The Seahorse neoprene perimeter O-ring seals out the elements, protecting the contents from water, dust, and other contaminants The O-ring comes standard with the case, however we recommend replacing the o-ring every couple of years.

TIP: To insure water resistance, keep the perimeter O-ring gasket free of cuts, abrasions and foreign debris (sand, grass, dirt, etc,), and check it on a regular basis. The best way to check the O-ring is by removing it from the case and wrapping it around your finger. Visually inspect different sections to ensure that there is no evidence of cracking, peeling or abrasions that could cause your case to leak.
