Value Collection 115AB20030 Pressure Gauge 30 Psi 2 in Npt

Product Description

The VALUE COLLECTION 115AB20030 is a liquid-filled analog pressure gauge designed for monitoring low-pressure systems in plumbing, HVAC, and light industrial applications. The gauge features a 2-inch dial with a 0 to 30 psi range and a 1/4-inch NPT center back mount, making it a compact, easy-to-read option for tight installation spaces. The glycerine fill dampens pointer vibration and protects the internal bourdon tube from pressure spikes, extending service life in systems with fluctuating pressures. Accuracy is rated at plus or minus 3-2-3 percent of scale. The stainless steel case and brass wetted parts offer solid corrosion resistance for most common trade fluid applications.

This gauge suits residential and light commercial installations where a reliable, low-cost pressure indicator is needed. Typical applications include water pressure monitoring, compressed air lines, boiler feed systems, and hydronic loops. The center back mount configuration fits panel or pipe-mounted installations where the supply line enters from behind. The glycerine fill makes it particularly useful in pump discharge or other vibration-prone locations where a dry gauge would chatter or wear prematurely.

Key Features

• 0 to 30 psi range with analog dial readout
• Glycerine-filled case reduces pointer vibration and extends internal component life
• Stainless steel case provides corrosion-resistant housing
• Brass wetted parts compatible with water, glycerine, and common system fluids
• 1/4-inch NPT center back mount for panel or pipe installation
• Plus or minus 3-2-3 percent of scale accuracy

Compatibility

Designed as an OEM-style replacement or service addition for residential and light commercial plumbing, HVAC, and hydronic systems requiring a 1/4-inch NPT center back mount pressure gauge rated to 30 psi.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Shut off and depressurize the system fully before removing or installing the gauge. Apply thread sealant or PTFE tape to the NPT threads in accordance with local plumbing codes before torquing by hand and then snugging with a wrench. Do not over-tighten, as this can crack the gauge body or damage the port fitting.
