Tradepro tp-gtestb-1/2-15 Bell Gauge 1/2 Npt 0-15 Psi

Product Description

The TRADEPRO tp-gtestb-1/2-15 is a bell-style pressure gauge with a 1/2 inch NPT connection and a measurement range of 0 to 15 psi. It is designed for monitoring low-pressure systems in HVAC, plumbing, and related mechanical applications. The gauge mounts directly to a threaded port on the system and provides a local pressure reading without the need for additional tooling. Licensed HVAC technicians and plumbers install this type of gauge during system commissioning, troubleshooting, and pressure testing. The 1/2 inch NPT thread is a standard connection size widely used across residential and light commercial mechanical systems.

This gauge is suited for low-pressure applications where a 0 to 15 psi range is appropriate. Typical install scenarios include gas supply lines operating at low pressure, hydronic heating system pressure taps, and plumbing test points. The bell-style housing provides a compact profile that fits in tight spaces common in mechanical rooms and equipment closets. It is sold as an individual unit and is intended for permanent or temporary installation at a dedicated pressure port.

Key Features

• 0 to 15 psi measurement range suitable for low-pressure system monitoring
• 1/2 inch NPT threaded connection for direct port mounting
• Bell-style gauge housing for compact, space-efficient installation
• Sold individually for single-point pressure monitoring applications

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems with a 1/2 inch NPT pressure port requiring a 0 to 15 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and depressurize the line before threading the gauge into the port. Apply appropriate thread sealant or PTFE tape to the NPT threads per local mechanical code requirements. Do not overtighten the gauge body, as damage to the bourdon tube or housing can result in inaccurate readings.
