Webstone H-81415KIT Pump Isolator Kit 1-1/4 in Press Flange

Product Description

The WEBSTONE H-81415KIT is a pump installation kit designed for hydronic and circulator pump applications. It includes isolator valves with a rotating flange configuration, allowing technicians to remove and service circulators without draining the system. The 1-1/4 inch press by rotating flange connection type suits copper piping installations and provides a reliable shutoff on both the inlet and outlet sides of the pump. This kit is typically installed by licensed plumbers and HVAC technicians working on closed-loop heating or cooling systems.

This kit is suited for residential and light commercial hydronic systems where circulator pump isolation is required. The press-fit end connections simplify installation in copper pipe systems, eliminating the need for solder joints at the valve body. The rotating flange end connects directly to standard circulator pump flanges, making pump swaps faster and more straightforward during service calls.
