Trerice Tridicators are designed specifically for use with hot water boilers. Because Tridicators provide both temperature and pressure measurement, only one access point to the boiler is required. Available in 2-1/2 in and 3 in dial sizes with rear and bottom connections, there is a Trerice Tridicator to suit your needs.
