Thermowell - Thru Wall Fitting

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 probe that connects to a Topside Command Center or a spa controller.

FOR ORDERING, PLEASE SEE PART NUMBERS 25-550-1020 AND 25-850-4510.

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 all SpaGuts temperature sensor probes must not be in direct water contact. The thermowell keeps the temperature sensor probe dry.

Dimensions are approximately 3 inches long x 1-3/8 inches wide. Requires a 1-1/8 inch round hole cut out.

Available in 5/16 inch or 3/8 inch temperature sensor probe fittings.

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