Weil McLain 640-000-073 Syphon Kit T1-T2 Wall Mount C

Description

The Weil McLain 640-000-073 is a factory-engineered Syphon Kit designed for T1-T2 wall-mount (WMnt C) boiler configurations. Syphon kits are a critical component in hydronic and steam heating systems, providing a protective water seal between live steam or high-temperature boiler water and the pressure gauges, aquastats, and sensing controls connected to the system.

Product Overview

This OEM syphon kit is specifically matched to Weil McLain boiler models requiring a T1-T2 wall-mount configuration. By trapping a column of cooler water between the boiler’s steam space and the connected control or gauge, the syphon prevents direct steam contact that could damage or degrade sensing components — helping to maintain accurate readings and extend the service life of connected controls.
