Dwyer Instruments tl25-100-4l Water Pressure Gauge 100 Psi

Product Description

The DWYER INSTRUMENTS tl25-100-4l is a utility-grade 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 100 psi and connects via a 0.25-inch male pipe thread (MPT) lower-mount fitting. The lower-mount configuration positions the connection at the bottom of the gauge body, making it straightforward to install directly into a tee, valve, or manifold port. Plumbers and mechanical contractors rely on gauges like this to verify operating pressure, check pump output, and confirm system balance during commissioning and service work.

This gauge is suited for residential and light commercial water systems, including potable water supply lines, boiler feed lines, irrigation systems, and pump discharge points. The 2.5-inch dial provides a readable display in tight panel or wall-mount installs where space is limited. The 0.25-inch MPT lower-mount inlet is a common connection size found throughout residential and commercial plumbing infrastructure, making this gauge a practical choice for a wide range of service and retrofit scenarios.

Key Features

• 100 psi pressure range suitable for standard residential and light commercial water systems
• 2.5-inch dial face for clear, readable pressure indication in compact installations
• 0.25-inch MPT lower-mount connection for direct inline or tee installation
• Utility-grade construction appropriate for water pressure monitoring in plumbing systems
• Lower-mount fitting orientation simplifies installation into bottom-port fittings and manifolds

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for residential and light commercial plumbing systems using 0.25-inch MPT lower-mount gauge ports rated to 100 psi or less.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician in accordance with applicable IPC and local plumbing codes. Shut off the water supply and relieve system pressure before removing any existing gauge or fitting. Apply thread sealant tape or pipe compound to the male threads before installation and hand-tighten before using a wrench to avoid cracking the gauge body. Do not exceed the rated 100 psi pressure range of the gauge.
