Dwyer Instruments tl25-015-4l Water Pressure Gauge 15 Psi

Product Description

The DWYER INSTRUMENTS tl25-015-4l is a utility water pressure gauge designed for monitoring system pressure in plumbing and mechanical applications. It features a 2.5 inch dial face with a range of 0 to 15 PSI and connects via a 0.25 inch male pipe thread (MPT) lower mount fitting. The lower mount configuration positions the inlet at the bottom of the gauge body, making it well suited for panel mounting and inline pipe installations. Plumbers, pipefitters, and mechanical contractors typically install this gauge on water supply lines, boiler systems, or pressure-regulated distribution systems where a compact, readable gauge is required.

This gauge is intended for utility water service in both residential and light commercial settings. The lower mount 0.25 inch MPT connection allows direct installation into a standard tee, manifold port, or gauge adapter without additional fittings in most common configurations. Its 2.5 inch dial provides clear pressure readings in environments where the gauge is mounted at or near eye level on a panel or riser assembly. It is a practical choice for service technicians verifying supply pressure, commissioning pressure-reducing valve stations, or monitoring closed-loop hydronic circuits.

Key Features

• 0 to 15 PSI pressure range suitable for low-pressure water utility service
• 2.5 inch dial face for readable display in compact installations
• 0.25 inch MPT lower mount connection for direct inline or panel installation
• Utility-grade construction appropriate for water pressure monitoring
• Bottom-entry fitting orientation supports upright panel and pipe-mounted installs

Compatibility

Designed as an OEM-style replacement or direct-install utility water pressure gauge for residential and light commercial plumbing systems equipped with standard 0.25 inch MPT gauge ports.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the water system before removing or installing any pressure gauge. Apply thread sealant tape to the MPT threads in accordance with local plumbing code before torquing the gauge into the fitting. Do not use the gauge body or dial as leverage during installation, as this can damage the Bourdon tube or pointer mechanism.
