Marshalltown Pressure Gauge in Metal Box – 0-20 oz/in² & 0-35 Inches of Water Column, 3-ft Rubber Hose for HVAC Pressure Measuring

Condition: Used – Fully functional. Includes 3-ft rubber hose with rubber cone end for flexible attachment to small-diameter pipes.

The Marshalltown HVAC Pressure Gauge is a precision measuring instrument designed for low-pressure applications, particularly in HVAC systems, gas lines pressure testing. This gauge measures both ounces per square inch (0-20 oz/in²) and inches of water column (0-35 inH₂O), making it an essential tool for technicians working with gas pressure testing, static pressure checks, and air balancing in HVAC systems.

Housed in a durable metal box (approx. 6″ x 5″ x 1 ¾”), this unit provides protection and portability. The included 3-ft rubber hose with a rubber cone-shaped end ensures secure and flexible attachment to small-diameter pipes without additional fittings, allowing for quick and reliable pressure readings.
