Hayward Pool Sand Filter Pressure Gauge Genuine Replacement Part ECX271261

The ECX271261 pressure gauge is a robust monitoring instrument specifically designed for professional Hayward HCF series sand filter systems. It is exceptionally durable and withstands the demanding operating conditions of large filters such as the S270T2 and S244SV models: higher operating pressures, greater flow fluctuations, and more aggressive chemical environments. Failure of original pressure gauges due to voltage spikes, chemical corrosion, or continuous operation under full load can lead to backwash setting errors, reduced filter performance, and even equipment damage. With our professional replacement pressure gauges, you choose superior durability and accuracy compared to original parts, ensuring optimal performance of large pool filter systems. 📦【Technical Specifications】Main Parameters: Original Model: ECX271261; Precision Compatible Parts; Measuring Range: 0–60 PSI / 0–4 bar (High-Resolution Dual-Unit Display); Accuracy Class: 2.0 (Commercial Standard, Error ±1.2 PSI); Connection standard: 1/4" NPT bottom thread (robust brass thread); Design features: solid copper Bourdon tube mechanism + double silicone oil damping system; Housing material: fiber-reinforced polycarbonate (FR-PC); Protection rating: IP65 (dustproof and waterproof, suitable for harsh outdoor environments); Operating temperature: -30°C to 100°C (extended temperature range); Shock resistance: withstands continuous vibrations of 0.5 G
