• Note the trick: Make sure you activate the internal thermostat by placing the unit in your freezer for 10 minutes or so before testing it. Otherwise it could be working fine but won't actually turn on because of the internal temp.
• Compatible with all rubbermaid stock tanks: The stock tank heater is perfectly compatible with for 50/70/100/150/300 Gallon rubbermaid stock tanks(FG424300BLA FG424288BLA FG424400BLA FG424500BLA FG424700BLA) and keep your existing rubbermaid stock tank in perfect working order.
• Please Note: Please ensure that the diameter of the drain plug hole in the rubbermaid trough is greater than 1.75IN, otherwise the replacement for rubbermaid stock tank heater may not be suitable or a new hole may need to be drilled. The stock tank heater can also be used for any agricultural plastic stock tank, but you may need to drill a hole larger than 1.75IN in size.
• Unique: Our water trough heater features high-precision temperature sensor that ensures long-lasting, efficient operation,and thermostatically controlled to operate only when necessary to prevent freezing for your horses. The high-density silicone fill not only eliminates water leakage from the unit but also provides excellent insulation between the water trough heater&the tank. This effectively prevents short circuits&ensures the GFCI wont trip, keeping your horses safe from electrical shocks.
• Effective Leakage Prevention: Our stock tank heater is equipped with thickened 8mm nut fixing ring&More inside diameter threads to reinforce the seal. In addition, the water trough heater also includes two flexible silicone gaskets. You can choose to place two rings inside the water trough or one inside and one outside to make the seal tighter. Silicone gaskets are made of high-density&highly flexible soft silicone material, which has superior sealing performance compared to other hard gaskets.
• High Hardness PA Plastic: This stock tank heater is made of upgraded high-density PA plastic with the highest hardness. The threads are harder&more wear-resistant, ensuring a tight seal and preventing easy detachment of the stock tank heater. The nut has a thickness of 8 millimeters, threads on much deeper and has a much better grip on the bullhead "through" portion of the fitting, which can provide a tighter seal and effectively resist high water pressure.
• Premium Copper: The copper tubing in our stock tank heater is made from 385 W/(mK) high-purity electrolytic copper, offering excellent thermal conductivity &ensuring fast water heating. The copper is highly corrosion-resistant, effectively withstanding changes in water quality and extending the water trough heater's lifespan. Additionally, the surface is specially treated to create a protective laynce and oxidation prevention, ensuring long-term use without leaks or performance degradation.
