Legend Valve 800-692 2-1/2 T&P 1/4 MPT Rear Mount accessory

Temperature & Pressure Gauge

The Legend Valve 800-692 is a 2-1/2 inch dial gauge designed for hydronic heating systems. It displays both temperature and pressure on a single rear-mount instrument. Installers use it on boilers and radiators where simultaneous monitoring is required. The 1/4 inch male NPT connection threads directly into standard tappings.

Operating Range & Mounting

The gauge reads from 60 to 280 degrees Fahrenheit, covering normal boiler operating temperatures. Rear mounting positions the dial flush against a panel or jacket for clean visibility. No external power is needed because the movement is purely mechanical. The brass internals withstand typical system pressures without leaking.
