Airmar: Includes black O-ring for safely retrofitting DT800V/DST800V into housings without valves. Ensures watertight seal and prevents dangerous leaks. Read more.
This black O-ring is used to replace the yellow O-ring when retrofitting a DT800V or DST800V sensor into a housing without a valve. The black O-ring creates a watertight seal. Failure to replace the yellow O-ring with the black O-ring may allow water to leak into the vessel, potentially causing property damage, personal injury, or death.
