Webstone h-58643 1 X 3/4 Sweat Primary Secondary Loop Purge Tee

Product Description

The Webstone h-58643 is a 1 inch by 3/4 inch sweat primary secondary loop purge tee designed for hydronic heating systems. HVAC technicians and plumbing professionals rely on this fitting to connect primary and secondary loops in hot water heating installations. The sweat connection style means the fittings are soldered directly onto copper pipe, creating a leak-free, permanent joint that holds up under the pressure and temperature demands of residential and commercial hydronic systems. Primary secondary loop piping is a widely used design strategy in modern radiant heat and forced hot water systems. It allows multiple secondary heating zones to branch off a single primary loop without disrupting flow balance across the system. Each secondary circuit connects to the primary loop through a closely spaced tee arrangement. The h-58643 makes this connection clean and straightforward, eliminating the need to assemble separate fittings on the job site. The 1 inch primary side handles the main loop flow while the 3/4 inch secondary port branches off to feed individual zones or air handlers. This size combination is common in residential and light commercial hydronic installations. Webstone is a well-regarded name in the hydronic and plumbing supply trade, known for producing valves and fittings built to work in demanding mechanical room environments. The purge tee design also supports system startup procedures, making it easier to bleed air from secondary circuits during commissioning. Hydronic heating contractors, mechanical insulation installers, and plumbing professionals working on new construction or retrofit projects will find this fitting useful. It is compatible with standard copper tube sizing and solders using conventional methods with lead-free solder as required by current plumbing codes.
