Product information

Description

Universal cup kit CT37-UCP-N for Honeywell CT37 and CT30 thermostats provides a compatible mechanical interface between the thermostat actuator and the valve or sensor housing. Supplied as a replacement or retrofit accessory, the cup restores correct alignment and reliable operation when the original cup is worn, cracked, or missing. The kit is intended for use in maintenance and repair tasks on heating control systems and is compatible with Honeywell CT37 and CT30 series installation geometries.

Advantages

The replacement cup kit ensures secure mechanical coupling and consistent stroke transfer from thermostat to valve or sensor fitting, reducing play and intermittent contact issues. Constructed from durable materials designed for long service life in typical room-temperature HVAC environments, the accessory simplifies field replacement and retrofit work. The universal geometry allows it to fit common mounting configurations used with CT37 and CT30 thermostats, helping technicians restore proper function without replacing the entire thermostat or actuator assembly.

Suitable for

  • Maintenance and repair of radiator thermostats
  • Retrofit installations where original cup is missing or damaged
  • Field replacement in residential and light commercial heating systems

Key specifications

  • Compatibility: designed for use with Honeywell CT37 and CT30 thermostat mounting geometries
  • Function: mechanical interface / coupling between thermostat actuator and valve or sensor housing
  • Material: durable polymer suitable for indoor HVAC applications
  • Supply form: replacement kit for retrofit and maintenance
  • Installation: intended for manual field replacement without special proprietary tools

How to use

Turn off heating or isolate the valve mechanism before beginning work. Remove the thermostat head or actuator from the valve or sensor housing and inspect the mounting area for debris or damage. Position the replacement cup on the valve or sensor spindle and align it with the thermostat coupling; slide the thermostat head into place and verify secure engagement and correct stroke transfer. Test the thermostat operation by adjusting setpoint and observing valve response. Reassemble any retained components and restore the system to service.

Usage recommendations

For safe and reliable installation, use basic hand tools and follow manufacturer guidance for thermostats and valves. Verify compatibility with CT37/CT30 geometry before fitting. If the valve or actuator shows corrosion or significant wear beyond the cup, consider replacing the affected components or consulting a qualified technician.
