Scanstrut DS21A-P Small Cable Seal, IP68 Waterproof, Fits Connectors to 0.83 Inch and Cables 0.165-0.35 Inch

The Scanstrut DS21A-P is a small vertical cable seal designed to route a single cable or connector through a deck, console, or enclosure while maintaining a fully watertight barrier. It handles cables from 0.165 to 0.35 inches in diameter and connectors up to 0.83 inches across, making it a compact solution for marine and outdoor electronics installations such as antenna leads, sensor cables, and instrument wiring.

The seal uses a tapered bung and closed-cell base to achieve an IP68 ingress rating without the need for additional sealant. A split-bung design allows the seal to be installed around a connector that is already terminated, so there is no need to remove large connectors during installation, which reduces both complexity and the risk of damage. The low-profile dome shape adds impact resistance and helps deflect water away from the seal point while keeping a sleek appearance on deck.

Construction is UV-stable, impact-resistant marine-grade plastic, paired with 316 stainless steel fixings and a 3M waterproof gasket for long-term corrosion resistance in a marine environment. Captive nuts are built into the design for fast, repeatable installation, and the seal ships with both pre-drilled and blank bungs so it can be customized to the exact cable or connector being routed.
