Whitecap 20" Gas Spring - 30lb - Black Nitrate

The Whitecap 20" Gas Spring - 30lb - Black Nitrate is a precision-engineered hydraulic strut designed for controlled lifting, lowering, and support applications across marine, automotive, and industrial equipment. Gas springs provide consistent force throughout their operating range, making them ideal for hatch covers, engine compartment lids, storage boxes, and any application requiring smooth, damped motion without mechanical locking. The 30-pound force rating and 20-inch extended length make this spring suitable for mid-range load support on compact to medium-sized enclosures and cabinets.

Built with a durable black nitride finish, this gas spring resists corrosion and wear in harsh marine and outdoor environments where standard steel springs would degrade. The unit features a 6mm rod diameter and 15mm tube diameter, engineered for durability and long-cycle life. With a compressed length of 12 inches and extended length of 20 inches, the 8-inch stroke provides substantial vertical or angular travel. The P1 (initial pressure) of 30 pounds ensures smooth extension and reliable performance across thousands of cycles, while the sealed nitrogen charge eliminates the need for maintenance or adjustment.

This Whitecap gas spring is most beneficial for boat and RV owners, equipment manufacturers, and technicians who need dependable support hardware for custom installations or OEM replacement. The compact 0.45-pound weight and precise dimensions (3 x 1 x 22 inches) allow easy integration into tight spaces. Installation typically requires simple rod-end and tube-end mounting brackets, making retrofit projects straightforward. Whether you're upgrading old mechanical hinges or designing new motorized or manual-opening systems, the Whitecap 20" spring delivers consistent, predictable performance in demanding environments.
