Brand: Ashcroft Inc
Request Information

Free Shipping on Orders Over $363.45 USD

Ashcroft direct drive pressure gauges are ideally suited for applications that demand reliability under rugged operating conditions.

The heart of the design is a spiral bourdon tube of Beryllium Copper - long recognized as a superior spring material. The spiral tube transmits motion directly to the pointer. There are no gears or bearings to wear out.

These Ashcroft pressure gauges are constructed with a stainless steel case and an impact resistant polycarbonate window to endure applications that require a weather-tight, dustproof and corrosion resistant enclosure.

Stringent process controls assure conformance to the most demanding customer quality expectations.

Choosing Ashcroft direct drive pressure gauges for your application is the right quality choice.
Features
  • Sealed stainless steel case provides a weatherproof, dustproof corrosion-resistant gauge 
  • Spiral tube transmits motion directly to the pointer - no gears or bearings to wear out 
  • High impact-resistant polycarbonate window 
  • UL 404 listed for compressed gas (including oxygen) for 1,500 psi, 2,000 psi, 3,000 psi and 4,000 psi
