Fits high-range process pressure indication where you need an Ashcroft 1379 Duragauge covering vacuum to 100,000 psi (50k–100k in 6 in case) with ±0.5% Grade 2A accuracy.
Key advantages
- Ranges — Vacuum, compound, 15 to 100,000 psi
- Accuracy — ±0.5% of span (ASME Grade 2A)
- Dials — 4.5 / 6 / 8.5 in solid-front Duragauge
- Case — Process solid-front construction
- Use — High-pressure process local indication
Typical applications
- High-pressure process gauges.
- Large-dial control-room adjacent indication.
- Vacuum through ultra-high psi Duragauge.
Selection guide
- Dial size — 4.5 vs 6 vs 8.5 in
- Ultra-high range — 50k–100k needs 6 in
- Connection / tube — Material system
- Fill options — Per datasheet
Common mistakes
- Wrong dial size for ultra-high ranges.
- Underspecifying tube material.
- Ignoring solid-front safety preference.
When to RFQ / what to tell us
- Dial size, range, connection, materials.
- Quantity and ship-to.
