Specifying the correct lens silicone sealing rings for underwater drone cameras is a mission-critical task. A poor seal means water ingress, ruined optics, and expensive ROV downtime. This guide walks you through the engineering parameters, material choices, and testing requirements — helping you source reliable seals from FromRubber. Underwater drones (ROVs) operate...

Common Industry Question · Answered by FromRubber Short answer: No, not all lens silicone O-rings are created equal. While silicone rubber generally offers moderate resistance to solvents like isopropyl alcohol (IPA) and poor resistance to acetone, the exact formulation, curing method, and additive package dramatically affect real-world compatibility. For optical p...
