• 1/2 inch NPT threaded outlet on bottom for connecting diaphragm expansion tank
• Never requires any servicing
• Maximum operating pressure of 125 psi and maximum operating temperature of 300°F

Specifications:

• Connection Size: 1-1/4 inch female NPT
• Recommended flow rate: 4 ft/sec, maximum flow rate: 8 ft/sec
• Flow coefficient (Cv): 54
• Dimensions: 6 inches length x 4 inches height
• Weight: 4.0 lbs

Ideal for closed-loop hydronic systems, the Taco 432-6 provides an economical solution for air elimination and can integrate with expansion tanks for complete system protection. Typically installed on the supply side directly off the boiler for optimal performance.
