Watts Water LF3001A-1-1/4 Dielectric Union 1-1/4" FPT x OD Lead Free
dielectric unions are used in commercial and residential applications to prevent accelerated corrosion and deterioration in the piping system due to galvanic and stray current. It is installed between pipes made from dissimilar metals and is used on applications such as hot water storage tanks, water and air conditioners, processing tanks, steam, gas, and water piping. It consists of a female iron pipe thread to solder connection, union nut, two tailpieces, and a Buna-N gasket that separates the tailpieces to prevent an electric current from occurring.

• Buna-N gasket Designed and manufactured to the highest quality standards
• Maximum pressure is 250 psi (17.2 bar)
• Maximum temperature 180 degrees F (82 degrees C)
• Individually factory certified to withstand a minimum of 600 volts on a dry line with no flashover
• FIP thread to solder connections
• Meets federal specifications for tensile strength and thread end connections,

Watts 9DM3 Forged Brass Dual Check Backflow Preventer with Intermediate Atmospheric Vent, 1/2", Female Union

• It prevent the reverse flow of hot or cold polluted water from entering into the potable water supply
• It consists of a brass body with stainless steel internal parts, integral strainer, and two durable, tight-sealing, rubber check valves
• For continuous pressure, non-health hazard applications in smaller supply lines
• It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing
• A secondary check valve utilizes a rubber disc-to-metal seating
• In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system
• True line-sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling
• Maximum flow at low pressure drop
• Furnished with union connections to facilitate removal and replacement for maintenance
• Compact for economy combined with performance
• Design simplicity for easy maintenance
• Can be installed vertically or horizontally
