Features

No Lead / Lead-Free Certified: Wetted parts (socket and movement) made from low-lead brass; meets NSF/ANSI 61 and 372 standards for drinking water systems. In no-lead brass alloys, lead is replaced with key elements such as bismuth and silicon while maintaining robust mechanical strength and corrosion resistance. This makes them important for potable water systems and food processing applications.

1/4" MPT Connection: Standard 1/4 inch Male National Pipe Thread; equivalent to a 1/4" NPT connection and fits most common pressure ports and manifolds using standard NPT threads.

0-100 PSI Range: Measures pressure from 0 to 100 pounds per square inch. This product is suitable for non-corrosive media such as water, oil, air, and compatible hydraulic fluids.

Bourdon Tube Sensing Element: Phosphor bronze C-shaped tube provides accurate pressure sensing and responds to pressure changes. No-lead brass also helps resist vibration-related damage, which supports accuracy and can reduce maintenance costs.

Dual Scale Display: Typically displays both PSI (primary) and kPa (secondary) for versatile use, with a dial that is easy to read.

±3-2-3% Accuracy (Grade B): Standard accuracy for general purpose gauges; mid-scale is most accurate. Hydronix gauges are tested for accuracy and leakage.

Variety of Dial Sizes: Available in 2", 2-1/2", and 4" dial diameters depending on application needs, including reverse osmosis systems and food processing plants. Liquid filled versions are used for more demanding environments if offered in the range.

Overview

A No Lead Brass Pressure Gauge is a mechanical instrument made with low-lead brass components, designed for measuring and displaying system pressure in residential, commercial, and industrial water and air systems; this style typically uses a 1/4" MPT (Male Pipe Thread) connection for standard pipe fittings, manifolds, or equipment ports and is a common fit for homeowners, agricultural users, light commercial property managers, and contractors selecting a potable-water-safe gauge.

This pressure gauge is certified "No Lead" or "Lead-Free," meaning the internal components that contact water contain less than 0.25% lead by weighted average, complying with federal and state low-lead laws for potable water systems; standard brass gauges are not permitted for potable water systems under federal plumbing laws, and the no-lead design helps prevent toxic lead from leaching into the fluid stream. This overview covers the key specs that drive the choice, including certifications, connection types, pressure range, accuracy, quality, and suitable applications. Lead-free gauges are intended for non-corrosive media.

The 100 PSI maximum pressure rating makes this gauge suitable for residential water systems, irrigation, air compressors, and light commercial applications where typical operating pressures range from 30 to 75 PSI, and no-lead brass performs similarly to standard brass under normal pressure and temperature ranges. It is kept in stock for buyers who need a potable-water-safe gauge ready for common system pressures.

Specification

Made from no lead bronze (C89833 or C89844)
Threads conform to ANSI/ASME B1.20.1
For use with ASTM D2239 polyethylene (PE) plastic pipe (Standard Specification for Polyethylene (PE) Pipe (SIDR-PR) Based on Controlled Inside Diameter)
System operating pressures and temperatures are limited by the maximum operating pressures and temperatures of the ASTM D2239 PE plastic pipe. Always refer to the PE pipe manufacturer's pressure and temperature ratings.
Insert fittings are intended for cold water applications including irrigation, well service, and potable water applications. These products are not to be used with compressed gases.
Fittings must be protected from freezing temperatures where fluid expansion due to freezing could occur.
