Whitecap 7-1/2" Gas Spring - 40lb - Stainless Steel

The Whitecap 7-1/2" Gas Spring - 40lb - Stainless Steel (MPN G-3140SSC) is a heavy-duty hydraulic support designed for marine, RV, automotive, and industrial applications requiring controlled lifting and lowering of hatches, doors, lids, and access panels. This gas spring provides reliable force assistance for equipment operators, reducing manual effort and improving safety by preventing sudden closure or drop of heavy components during maintenance, storage, or operation.

Built from premium 316 stainless steel, this gas spring resists corrosion in saltwater, humid, and chemically harsh environments—making it ideal for marine and coastal installations. The unit features a 6mm rod diameter and 15mm tube diameter, with an extended length of 7-1/2 inches and compressed length of 5-1/2 inches, allowing flexible mounting in compact spaces. The 40lb force rating (P1) delivers smooth, consistent support across the full stroke, powered by sealed nitrogen gas that maintains performance over thousands of cycles without leakage or degradation.

This stainless steel gas spring is best suited for marine equipment, boat hardware, RV systems, and industrial enclosures where corrosion resistance and durability are non-negotiable. Installation requires simple pivot-pin or threaded-end mounting at both rod and tube ends; verify your application's force requirements and stroke length before ordering. The 40lb rating accommodates panels and lids weighing 30–50 pounds under typical gravity conditions, though final sizing depends on mounting angle and specific load distribution.
