Thermowell, Thru Wall Fitting, 3/8-inch

A Thru Wall Thermowell is a small fitting that goes through your spa shell to help measure the temperature of your water. Inserted in the thermowell is a temperature sensor probe that connects to a Topside Command Center or a Spa Controller. This is a dry thermowell that fits a 3/8 inch temperature sensor probe, and keeps it dry.

SpaGuts P/N: 25-550-1020

Thru Wall Thermowells are a more precise way of measuring the temperature of the water in the spa than measuring the water temperature flowing through a plumbing fitting or a heater. Keep in mind that SpaGuts CS-Series temperature sensor probes must not be in direct water contact. This dry thermowell keeps the temperature sensor probe dry.

Dimensions (Approx): 3 inches long x 1-3/8 inches lip diameter. Requires a 1-1/8 inch round hole cut out for installation.

This item includes the drywell, securing nut, wall gasket, and split rubber grommet.
