2-1/2" x 3/4" Water Test Gauge, Female Thread

Wal-Rich 1721002 – 2-1/2" Water Pressure Test Gauge with 3/4" FHT Connection

The Wal-Rich 1721002 is a mechanical water pressure test gauge designed for evaluating system pressure in residential and commercial plumbing installations. This model features a 2-1/2" dial face and a 3/4" female hose thread (FHT) fitting, allowing for quick attachment to hose bibbs or other threaded outlets. Rated up to 200 PSI, it is suitable for verifying system pressure and performing diagnostic checks on pressurized lines.

Application and Use

• Gauge Diameter: 2-1/2 inch for improved readability
• Connection Type: 3/4" female garden hose thread (FHT)
• Pressure Range: 0–200 PSI
• Graduation: 2 PSI increments for measurement resolution
• Use Case: Temporary pressure testing at hose bibbs, boiler drains, or supply outlets

Construction Features

• Body Material: Steel gauge housing
• Lens: Clear acrylic face for durability and visibility
• Thread Material: Brass hose thread for corrosion resistance
• Mount Type: Rear-mounted pressure dial with bottom-thread connection

Installation Considerations

This gauge is intended for temporary diagnostic use. It threads directly onto a 3/4" male garden hose fitting with no additional adapters required. Do not leave the gauge installed under continuous pressure beyond the test window. Always verify system shutoff before connecting to avoid water discharge during installation.

Field Use Notes for Technicians

• Use to verify static and dynamic water pressure at outdoor hose connections, boiler drain valves, or other standard 3/4" male hose threads.
• Monitor for fluctuations or pressure loss in municipal or private supply lines.
• Do not exceed the maximum rated pressure of 200 PSI.

Summary

The Wal-Rich 1721002 is a pressure test gauge built for field-ready diagnostics, featuring a durable analog face and standard hose thread compatibility. Designed for professional use, it is a reliable solution for quickly assessing water supply conditions during service calls or post-installation inspections.
