Whitecap 7-1/2" Gas Spring - 20lb - Stainless Steel

The Whitecap 7-1/2" Gas Spring – 20lb – Stainless Steel (G-3120SSC) is a 316 stainless steel pneumatic support component engineered for marine, industrial, and tactical equipment requiring reliable counterforce during opening and closing cycles. Constructed from marine-grade austenitic stainless steel, this gas spring delivers corrosion resistance essential for saltwater environments, coastal operations, and high-humidity field conditions where standard mild-steel components degrade rapidly.

Technical specifications are optimized for precision mounting applications. The unit extends to 7-1/2 inches and compresses to 5-1/2 inches, providing a 2-inch stroke length suitable for hatch covers, equipment access panels, and field gear compartments. The 6mm rod diameter paired with a 15mm tube diameter creates a compact profile while maintaining structural rigidity under load cycles. The 20-pound force rating (P1) provides measured resistance appropriate for lightweight covers and access points without requiring significant operator force to overcome. Rod and tube tolerances ensure smooth, repeatable cycling across thousands of operational cycles without binding or performance degradation.

This gas spring is deployed in marine hardware installations, military storage systems, vehicle equipment mounts, and offshore equipment housings where corrosion resistance and long service life outweigh cost considerations. The 316 stainless construction prevents salt-air degradation, rust bloom, and structural failure in coastal bases, maritime vessels, and remote field stations. Weight of 0.2 pounds ensures minimal load impact on larger assemblies.

Gas springs in the 15–25 pound range are the standard for access covers and hatches requiring operator-assisted opening without full mechanical support. The stainless steel specification distinguishes this component from commodity zinc-plated alternatives, adding 40–60% to material cost but extending service intervals in corrosive environments by 5–10 years compared to standard steel versions.
