PVC underwater housings can be a very useful and cost efficient way of getting instrumentation underwater, and we often have these in stock for quick delivery. The housings have an operational depth limit of 100m and our new hybrid designs have different endcap material options such as Plastic, Acrylic and Aluminum. Pros:

  • Low Cost
  • Material is Mostly Available
  • Dielectric Material (No Dissimilar Metal Concerns)
  • Light Weight .04-.056 lb/cubic Inch


  • Low Strength
  • Shallow Operations Only
  • Aluminum May Cost Less
  • Brittle in Cold Environments
  • Poor Thermal Conductivity
