Amtrol THERM-X-TROL Water Heater Expansion Tank ST-5, 2 Gallons Thermal expansion occurs as domestic water is heated. Left unchecked, the resulting pressure increase can cause relief valve discharge and other potentially hazardous conditions. Therm-X-Trol expansion tanks absorb this expanded water, keeping water pressure at a safe level. Features: Antimicrobial liner neutralizes bacteria on contactPatent pending Turbulator water diffuser50 psi precharge - the industry's highestDeep drawn steel domes...

This non-potable water expansion tank is designed for use in commercial and residential closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief setting of the relief valve. This carbon steel tank is pre-charged at 12 psi, tank volume is 15.0 gallons and features a durable expansion membrane that prevents contact of the water with the air in the tank. This rugged butyl diaphragm minimizes loss of the air change and ensures...

Taco Hy-Vent, 1/4" Npt, 150 Psi The high-capacity, float-style vent can be placed either on the boiler or at the high points throughout the system. With threaded connections--1/8". 1/4", 1/2" and 3/4" --and operating pressure ratings up to 250 psi, these brass-body, nickel-plated vents meet the system requirements of even your largest installations.

General Purpose FS4-3 Flow Switch Universal design serves the widest variety of applications. Used for starting or stopping electrically operated equipment such as signal lights, alarms, motors, automatic burners and metering devices. 1" NPT connection, single pole, double throw switching. Sealed Monel Bellow. Two electrical knock-outs allows connection from either end. Four stainless steel paddles included: 1", 2", 3" & 6".
