Astral / Hurlcon Bottom Entry Lower Mount Pressure Gauge
🏷️ Brand
Astral (genuine) / Generic option available
📝 Description
The Astral 75032 is the genuine bottom entry (lower mount) pressure gauge for Astral and Hurlcon filters, including Viron QL, Filtrite CF and Ultra Fine UF cartridge filters, and older RX, FG, E-Series and Viron CL filters.
This listing has two options. Astral is the genuine 75032 gauge. Generic is the Aussie Gold lower mount oil filled pressure gauge (PG05).
The pressure gauge shows how hard your filter is working. Note the reading when the filter is clean, then clean or backwash when it rises above that. A gauge that sticks, reads zero with the pump running or has fogged up should be replaced.
