Weiss Instruments TL25-15-4L Pressure Gauge 0-15 Psi

Product Description

The WEISS INSTRUMENTS TL25-15-4L is a 2.5-inch dial pressure gauge designed for accurate pressure measurement in HVAC and pneumatic system applications. It covers a gauge pressure range of 0 to 15 psi with an accuracy of plus or minus 2 percent full scale. The case is constructed from drawn steel with a black finish and a push-in polycarbonate window, providing durable protection in typical mechanical and mechanical-room environments. The lower-fitting connection allows for bottom-mount installation, making it compatible with standard manifold and pipe-mounted configurations. Licensed HVAC technicians and pneumatic system installers use this gauge to monitor system pressures during commissioning and routine service.

This gauge is suited for residential and light commercial HVAC systems as well as pneumatic control systems where a compact, reliable low-pressure indicator is required. The bottom-mount connection accommodates direct pipe or manifold mounting in tight equipment spaces. Wetted parts are brass and bronze, making the gauge compatible with air, water, and other non-corrosive media commonly found in HVAC and pneumatic applications.

Key Features

• 2.5-inch dial diameter for easy readability in field conditions
• 0 to 15 psi gauge pressure range suited to low-pressure HVAC and pneumatic circuits
• Plus or minus 2 percent full-scale accuracy for reliable pressure monitoring
• Drawn steel case with black finish and push-in polycarbonate window for durable, low-profile construction
• Bottom-mount lower-fitting connection for direct pipe or manifold installation
• Brass and bronze wetted parts compatible with common non-corrosive system media

Compatibility

Designed as an OEM-style replacement or new-install pressure gauge for HVAC and pneumatic systems requiring a 2.5-inch dial, bottom-mount gauge pressure instrument in the 0 to 15 psi range.

Installation Notes

Installation should be performed by a qualified HVAC technician or pipefitter in accordance with applicable mechanical codes. Depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant to male pipe threads per the fitting manufacturer guidance, and do not overtighten the connection fitting. Verify the gauge range is appropriate for the operating pressure of the system before returning to service.
