Fill with

3 to 4 in. of sealant

Attach 3/4 in. watertight pipe to the top of the preamplifier. Secure the threaded connection to prevent any leakage. For additional defense against possible accumulation of condensation at the back seal area of the sensor, fill the lower 3-4 inches (75-100 mm) of conduit or extension pipe with a flexible sealant such as silicone.
