Dwyer Instruments tl25-060-4l Pressure Gauge 60 Psi

Product Description

The DWYER INSTRUMENTS tl25-060-4l is a utility water pressure gauge designed for monitoring system pressure in plumbing and HVAC applications. It features a 2.5-inch dial face with a 0 to 60 psi range, making it suitable for reading line pressures on domestic water systems, boiler supply lines, and similar low-to-moderate-pressure circuits. The 0.25-inch male pipe thread (MPT) lower-mount connection allows direct inline installation on standard pipe fittings. Licensed plumbers and HVAC technicians install this type of gauge as a permanent or service-point instrument to verify operating pressure at a glance.

This gauge is suited for residential and light commercial water systems where a compact, direct-mount pressure indicator is needed. The lower-mount configuration positions the dial face upright when the gauge is threaded into a vertical or horizontal pipe run from below, which is a common installation point on pressure reducing valve (PRV) outlets, boiler supply lines, pump discharge ports, and similar service locations. No external power source is required.

Key Features

• 2.5-inch dial face for easy at-a-glance pressure readings
• 0 to 60 psi range suited for domestic water and hydronic systems
• 0.25-inch MPT lower-mount connection for direct inline installation
• Utility-grade construction appropriate for water service applications
• Compact form factor fits standard pipe fittings without additional adapters

Compatibility

Designed as an OEM-style replacement or service-point addition for residential and light commercial plumbing and hydronic systems requiring a 2.5-inch dial, 0.25-inch MPT lower-mount pressure gauge rated to 60 psi.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and relieve line pressure before removing or installing any gauge fitting. Apply thread sealant or PTFE tape to the MPT threads in accordance with IPC guidelines before threading into the port. Do not over-tighten the gauge body; use a wrench on the hex fitting, not the dial case, to avoid damaging the Bourdon tube or dial assembly.
