Overview
The Ashcroft Duragauge 0-600 PSI is a high-performance analog pressure gauge engineered for HVAC, refrigeration, and general industrial use. With a 4.5″ ASME style design, this gauge combines comprehensive safety and reliability features. The dry-fill construction makes it ideal for systems where liquid fill is not required, and the 0-600 psi range with ½ NPT male lower connection ensures compatibility with standard refrigeration and pneumatic systems.
Key Features
- Phenolic case with robust, Teflon® coated 400 series stainless steel movement for smooth and reliable performance
- ±0.5% accuracy (ASME B40.100 Grade 2A)
- Patented Duratubeâ„¢ and “Round Cap Tip” Bourdon tube construction controls stresses for longer life
- Dry gauge fill eliminates concerns with glycerin yellowing or viscosity changes
- Withstands continuous operating temperatures up to 250 °F (121 °C)
- Standard ½ NPT male connection for drop-in retrofit applications

Replaces / Drop-In Replacement For
Verify specific part compatibility with your system integrator. Ashcroft produces the Duragauge in models 1279, 1377, 1379, and 2462, each available in multiple ranges including 0–600 PSI. This gauge may serve as a direct replacement for like-for-like 0–600 PSI Duragauge units with ½ NPT lower connection; confirm exact model number before ordering.
Works With
- HVAC service manifolds and charging hoses
- Pressure test equipment and diagnostic toolkits
- Refrigeration recovery and recycling equipment
- Manual pressure monitoring systems (analog-only)
