Robertshaw 4290-033 Gas Thermostat

The Robertshaw 4290-033 is a heavy-duty GS-series commercial gas thermostat engineered for high-performance temperature regulation in demanding commercial kitchens. This hydraulic thermostat utilizes a precision-machined snap-action mechanism to provide immediate gas flow interruption or engagement, maintaining tight tolerances within a 200°F to 400°F temperature range. Designed for versatility, it is an essential component for commercial fryer replacement parts, warming cabinets, griddles, and small ovens where consistent heat management is critical for food safety and operational throughput.

Featuring a 30-inch capillary and a 1/4-inch nickel-plated bulb, this unit ensures reliable thermal feedback even in confined mounting spaces. The 1/4-inch tube inlet and outlet configuration allows for easy integration into existing gas manifolds, supporting capacities up to 30,000 BTUs. For technicians overseeing high-volume lines, the Robertshaw 4290-033 200/400F offers a rugged solution that withstands ambient temperatures up to 300°F, ensuring long-term stability without the drift common in lower-grade alternatives.
