SKB pressure release valves let a sealed case equalize with outside air, so it opens easily after a flight or a temperature swing instead of fighting a vacuum. The category also covers humidity indicators that show the relative humidity inside the case without opening it. Valves and indicators for compatible SKB cases.
Pressure & Humidity Control
SKB Pressure Release Valves and Humidity Indicators
Automatic Or Manual Valves • Humidity Indicators • Threaded Case Ports
A sealed case crossing altitudes or temperatures builds a pressure differential. A valve lets it equalize without letting water in.
Choose automatic venting for hands-off equalization or a manual valve for control, and match the humidity indicator range to the threshold you need to watch.
Let the Pressure Out, Keep the Water Out Automatic valves vent continuously while manual valves open and close on demand, and humidity indicators report the moisture level inside without breaking the seal. Match the valve type and the indicator range to how your cases travel and what they carry.
