Whitecap 12" Gas Spring - 90lb - Black Nitrate

The Whitecap 12" Gas Spring - 90lb - Black Nitrate is a heavy-duty hydraulic strut designed for marine hatches, engine compartments, and cabin doors on recreational and commercial vessels. After years working the water, you know that reliable hardware makes the difference between smooth operation and frustrating maintenance calls. This gas spring holds its force consistently across temperature swings and repeated cycles, eliminating the wear and flex of mechanical hinges or latches.

Built with a sealed nitrate-coated steel cylinder and precision-engineered internals, the Whitecap gas spring delivers a steady 90-pound support force throughout its stroke. The 8mm rod and 18mm tube diameter provide robust structural integrity while resisting corrosion from salt spray and fresh water exposure. At full extension it measures 12 inches, compressing down to 8.5 inches under load—a compact footprint that fits tight engine bays and galley spaces. The black nitrate finish protects against rust and maintains a clean, professional appearance below deck or in exposed equipment areas.

Anglers and cruisers who upgrade worn hatches, battery box covers, or cabin ventilation doors will appreciate the effortless support and smooth closing action this strut provides. Installation is straightforward—the compact design works with standard mounting brackets, and the consistent 90lb force suits small to mid-size hatches and compartment doors found on center consoles, cabin cruisers, and pontoons. Whether you're retrofitting aging hardware or building out a new vessel, this Whitecap gas spring handles freshwater and saltwater environments without sacrificing durability or reliable performance season after season.
