Compiled from manufacturer catalog strings and distributor listings. Verify against your own equipment's parts manual before ordering. This is not an offer or a quotation.
Distributor specification only. The RX is identified by a 3/8 in bulb and a 24 in capillary, which is what makes it physically different from the KX and K units with the same temperature range.

Controls fryer oil temperature on Hobart 1HG series gas fryers (the burner-component section of Hobart manual F-43118 Rev. A lists this part) and on Vulcan/Wolf fryers. Supplied as a kit including knob and screws.
A vapour-charged sensing bulb and capillary drive a diaphragm; the dial biases a set of contacts against it. There is no electronics inside. When a unit like this fails it fails in one of four ways: the contacts weld closed (heat keeps rising), the contacts open and stay open (no heat at all), the charge is lost through a cracked bulb or a kinked capillary (the unit behaves as if the oil is always cold), or the calibration drifts so the dial no longer matches the oil temperature. Only the last one still 'works' — which is why it is the one that quietly overcooks oil or trips the hi-limit.
| Symptom | This part? | Check first |
|---|---|---|
| Oil keeps climbing past the dial setting until the hi-limit trips | Yes — contacts welded closed | Hi-limit continuity first; whether the burner stays lit with the dial turned to OFF |
| No heat, pilot or ignition sequence fine, dial turned up | Possible — contacts open, or charge lost | Gas-valve operator signal, hi-limit continuity, ignition sequence |
| Dial setting and oil temperature disagree by more than a few degrees | Possible — drift, or a fouled / mis-seated bulb | Bulb coating and immersion depth; cross-check the oil with a separate thermometer |
| Dial turns with no resistance, or no click at either end of the range | Possible — stripped shaft or detached capillary | Capillary routing at the stuffing box (kinks, crushed sections) |

Distributor interchange tables report 00-913153 (and 111506-13, 111506-8, 721025-1) as interchangeable numbers for the same RX thermostat kit. These cross-references come from distributor tables rather than manufacturer statements.
24 in capillary, 200–400 °F.
This RX millivolt thermostat is widely cross-referenced to the Robertshaw RX-2-24 (capillary-length variants are listed as RX-10-24 / RX-2-30) and distributor equivalents such as AllPoints 461183 / 5300-40B. Reported cross-references come from distributor catalogs rather than manufacturer statements.
Yes — it is supplied as a kit with knob and screws.
Capillary, millivolt and high-limit thermostats in these part families are produced in volume in China. Public supplier directories list manufacturers concentrated in specific industrial clusters: Zhongshan (Guangdong) for capillary, millivolt and deep-fryer thermostats; Wenzhou (Zhejiang) for capillary, gas, immersion and mechanical thermostats with OEM/ODM capability; and Jinan (Shandong) for gas-valve and thermostatic gas-control components. When sourcing these parts from China, verify: dimensional drawings, sensing-bulb and capillary specifications, temperature accuracy, electrical ratings, cycle-life testing and applicable safety certifications (CE / CQC / UL). A high-limit safety thermostat must not be substituted on the basis of physical fit alone.
