Hayward GAUGE ADAPTER

The Hayward Gauge Adapter is a specialized plumbing fitting designed to provide a secure and leak-free connection between the filter's pressure gauge and the filter head or air relief assembly. Manufactured from high-strength, chemical-resistant plastic or reinforced composite, this adapter features precision-molded threads that allow for the easy installation of a standard NPT pressure gauge into the pressurized filter vessel. Its primary mechanical function is to bridge the size difference between the gauge stem and the filter port while maintaining a hermetic seal under high hydraulic pressure, ensuring that the system can accurately monitor internal filtration performance. The adapter is engineered to withstand the vibration of the pump and the corrosive effects of pool chemicals like chlorine and salt, preventing the cracking or cross-threading that can lead to hazardous pressure leaks. By providing a stable mounting point, it protects the sensitive internals of the gauge from direct mechanical stress during routine maintenance or filter bumping. For shipping and logistical purposes, the estimated weight of the Hayward Gauge Adapter is approximately 0.12 pounds in its retail protective packaging, while the actual dry weight of the individual fitting is roughly 0.05 pounds.
