4" Gauges

Our 4" Allenco series AG-1000L gauges are typically used as a hydrant gauge for flow testing and are available in the following ranges:

• 0-60 PSI
• 0-100 PSI
• 0-200 PSI
• 0-300 PSI
• 0-400 PSI
  

These high quality gauges are manufactured to ANSI B.40.1 Grade 1A standards, are 1% accurate over the entire gauge range and conform to NFPA 20-2010 (14.2.5.1.2) as it relates to gauge accuracy.

The standard glycerine filling helps to provide a steadier gauge reading while also lubricating the gauge movement which helps to extend the gauge life.

These gauges have a 4" dial, PSI scale, stainless steel case, brass internals, and bronze bourdon tube with 1/4" NPT lower connection.

Calibrated gauges include test report and serial number. Gauges are tagged with serial number, customer name and calibration date. Annual re-certification is available.

Calibrated Gauges typically ship in 2-3 business days

Optional Gauge Accessory Kit includes (1) 1/4" Ball Valve, (1) 1/4" Street 90, and (1) 1/4" x 5" Nipple.

Optional Quick Disconnect Kit protects your gauges during repeated temporary installations, includes (1) Female Quick Disconnect and (1) Male Quick Disconnect 

Our Allenco series AG-3000D dry utility gauges are an inexpensive commercial quality gauge suitable for use where precise pressure readings are not required. 

These gauges are manufactured to ANSI B.40.1 Grade B standards with 3-2-3% accuracy and do not meet the accuracy requirements of NFPA 20 for fire pump testing. These gauges are typically installed in fire pump installations to provide a general indication of pump pressures and performance.
