Parts to Your Door 50630 Thermowell 3/4 Inch Extended

Product Description

The PARTS TO YOUR DOOR 50630 is a 3/4-inch extended thermowell designed for use with Honeywell Aquastat controllers in hydronic heating systems. A thermowell provides a dry-well immersion point that allows a temperature sensor or aquastat bulb to read fluid temperature without direct contact with the system fluid. The extended length of this well accommodates deeper insertion into boiler piping, ensuring accurate sensing. Licensed plumbers and HVAC technicians install this component during boiler service, control replacement, or new hydronic system commissioning.

This thermowell is used in residential and light-commercial hydronic heating applications, specifically where a Honeywell Aquastat long-bulb controller is installed on a boiler or hot-water heating loop. It threads into the boiler or supply piping at a 3/4-inch fitting, positioning the aquastat sensing element within the water flow for reliable temperature control. It is a direct-fit replacement for the original Peerless 50630 thermowell found on Peerless boiler installations.

Key Features

• Extended thermowell length accommodates long-bulb Honeywell Aquastat sensing elements
• 3/4-inch pipe thread connection for standard boiler and hydronic piping fitment
• Dry-well design isolates the sensor from direct fluid contact, protecting the control
• Direct replacement for the original Peerless 50630 component

Compatibility

Designed for use with Honeywell Aquastat long-bulb controllers. Referenced as a replacement for the Peerless 50630 thermowell used on Peerless boiler installations with 3/4-inch thermowell ports.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with hydronic heating systems. Shut down and depressurize the boiler and allow the system to cool before removing or installing any thermowell. Apply appropriate thread sealant or PTFE tape to the pipe threads before installation. Verify the aquastat bulb seats fully within the well after installation to ensure accurate temperature sensing.
