Whitecap 7-1/2" Gas Spring - 40lb - Black Nitrate

The Whitecap 7-1/2" Gas Spring - 40lb - Black Nitrate (model G-3140C) is a hydraulic support component designed for boat hatches, engine covers, and cabin doors that need controlled, hands-free operation. This product is essential for ensuring safety and efficiency in marine environments, where hardware failure can lead to significant risks and downtime.

Constructed with a sealed nitrogen-charged cylinder and a black nitrate-finished steel rod, the Whitecap gas spring provides a consistent lifting force of 40 pounds across a full range of opening angles. This design prevents sudden drops or slams that can damage surfaces, pinch fingers, or wear out hinges prematurely. The nitrate coating offers excellent corrosion resistance against salt spray, UV exposure, and moisture, making it ideal for outdoor use.

Whether you're retrofitting an older vessel or upgrading hardware on a newer build, this gas spring is compatible with standard ball-socket and rod-eye fittings (sold separately) for easy installation. It is particularly beneficial for applications requiring both positive and negative pressure, such as cabin ventilation and engine compartment access. The 40lb force rating effectively supports covers and doors weighing up to approximately 30–40 pounds, depending on leverage and mounting geometry.
