Pelican Products 1443 Replacement O-Ring 49.2 inch for 1440 Series Top Load Cases

Replacement O-Ring for 1440 Cases

The Pelican 1443 O-ring is a precision-engineered seal designed exclusively for 1440 series top load cases. It restores the original watertight and dustproof barrier when the factory-fitted ring wears out. Maintenance teams and case owners use it to keep sensitive equipment protected from moisture and particulate ingress. The 49.2-inch neoprene sponge ring seats directly into the case groove for a factory-spec fit.

Neoprene Sponge Durability

High-quality neoprene sponge construction resists compression set and degradation from repeated opening and closing cycles. The material maintains elasticity across temperature swings encountered in field transport and storage. No lubricants or adhesives are required for installation, so the seal remains clean and non-contaminating. This preserves the case's protective rating without increasing closure force or latch effort.

Maintenance-Ready Component

The O-ring ships as a single continuous loop ready for immediate installation into the 1440 case groove. No cutting, splicing or additional hardware is supplied or needed. Replacing the seal returns the case to its original environmental specification, extending the service life of both the case and the equipment inside. It is a direct replacement part, not an upgrade or modification kit.
