Dwyer Instruments tl25-200-4l Pressure Gauge 200 Psi

Product Description

The DWYER INSTRUMENTS tl25-200-4l is a utility water pressure gauge designed for monitoring water system pressure in plumbing and HVAC applications. It features a 2.5 inch dial face with a range of 0 to 200 psi, making it suited for standard residential and light commercial water service lines. The 0.25 inch male pipe thread (MPT) lower mount connection allows direct inline installation at the base of the gauge body. Licensed plumbers and HVAC technicians install this type of gauge for system commissioning, pressure verification, and ongoing service diagnostics.

This gauge is appropriate for utility water pressure monitoring in residential and commercial plumbing systems, boiler feed lines, domestic water supply, and general-purpose hydronic applications. The lower mount configuration positions the dial face upright for easy reading when the gauge is threaded into a tee, valve body, or pressure port on a horizontal or vertical pipe run. Its compact 2.5 inch dial is a common choice for tight equipment rooms and mechanical spaces where panel space is limited.

Key Features

• 200 psi pressure range suitable for standard utility water service
• 2.5 inch dial face for clear, readable pressure indication
• 0.25 inch MPT lower mount connection for direct inline installation
• Utility-grade construction for general plumbing and HVAC pressure monitoring
• Compact form factor fits tight mechanical spaces and equipment rooms

Compatibility

Designed as an OEM-style replacement or service gauge for residential and light commercial plumbing and HVAC systems requiring a 0.25 inch MPT lower mount pressure gauge with a 2.5 inch dial and 200 psi range.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off system water supply and relieve line pressure completely before threading the gauge into the port. Apply thread sealant tape or pipe compound to the male threads per applicable IPC guidelines before hand-tightening and final torque with a wrench. Do not over-tighten, as this can crack the gauge body or distort the bourdon tube.
