SKB 3R Series Waterproof Shipping Cases | Airtight & Watertight Cases

The SKB Cases 3R Series is a heavy-duty line of rotomolded waterproof shipping cases engineered for mission-critical transport and long-term equipment protection. Manufactured by SKB Cases, the 3R Series is molded from linear low-density polyethylene (LLDPE) that is impact resistant, UV stabilized, and built to withstand the most demanding shipping, transit, and deployment environments.

Designed to meet or exceed MIL-STD-810H and MIL-C-4150J requirements, SKB 3R Series cases are fully airtight and watertight, featuring a gasket-sealed design, stainless steel latches and hinges, integrated lid straps, and an automatic ambient pressure equalization valve. These cases are also ATA 300 Category 1 rated and IP67 ingress protection certified, making them ideal for military, government, industrial, and commercial applications where reliability is non-negotiable—backed by engineered transport case solutions developed for mission-critical environments.

Available SKB 3R Series Case Sizes & Configurations

The 3R Series lines of shipping cases are available with an empty interior, cubed foam layers, layered foam, padded dividers or complete custom foam interiors. Many case sizes are also available with pull handle with wheels, depending on the size selected. Select sizes are also available with TSA recognized and accepted locking latches in place of stainless steel pad-lockable latches.
