Ashcroft 35-1009SW-02L Industrial Duralife Gauge

Ashcroft 35-1009SW-02L is a Duralife industrial pressure gauge built for harsh process environments, featuring a 3.5‑inch dial and 316L stainless steel wetted parts for robust chemical resistance. The “02L” designation indicates a 1/4‑inch NPT lower‑mount connection, making it well suited for bottom-entry installations in piping or vessels. Part of the 1009 Duralife family, it uses a PowerFlex movement to isolate the mechanism from shock and vibration, delivers ASME Grade 1A accuracy at full scale, and includes a True Zero pointer for immediate, unambiguous zero reading. The case is all stainless and welded, designed to withstand aggressive media and weather exposure, with options for either dry operation or glycerin‑filled liquid interfaces to improve pulsation resistance. The 1009SW designation also supports various configuration options, including different fills and mounting variants, while maintaining a durable, long‑life design. This gauge is commonly chosen for process monitoring in chemical, petrochemical, oil and gas, and water treatment environments where corrosion resistance and reliable readings are essential. To enhance readability and reliability, Ashcroft’s Duralife gauges are backed by a five‑year limited warranty, reflecting their emphasis on long‑term performance in demanding industrial settings.
