Safeguard your pool heater with the Swimables Pressure Switch SW-43-737, a critical safety component built for Raypak Low Nox heater models. This switch continuously tracks the water pressure flowing through the heater and triggers an automatic shutdown whenever pressure readings move outside the safe operating window. That automatic cutoff protects both the heat exchanger from damage and swimmers from hazardous conditions. Fabricated from heavy-duty materials chosen for their heat and moisture tolerance, the SW-43-737 delivers reliable sensing performance season after season. When your existing pressure switch begins to malfunction or fail, replacing it promptly with this unit restores the protective safeguard your heater was designed to have.

Key Benefits

• Continuous Pressure Surveillance: Actively tracks water pressure inside the heater in real time and initiates an automatic shutdown when readings deviate from safe parameters.
• Critical Safety Protection: Prevents the heater from firing when water flow is insufficient or pressure is abnormal, shielding equipment and users from dangerous operating conditions.
• Heavy-Duty, Heat-Tolerant Build: Constructed from materials engineered to perform reliably in the high-temperature, high-moisture environment surrounding pool heaters.
• Quick Replacement, Restored Protection: Straightforward installation process gets your heater's safety interlock back online fast, minimizing downtime and exposure to unprotected operation.
