Watts 68097 Isolation Pump Flange 1-1/4 in Sweat

Product Description

The WATTS 68097 is a 1-1/4 inch sweat-end isolation pump flange engineered to isolate circulator pumps in hydronic heating and closed-loop plumbing systems. The flange allows a circulator to be removed or replaced without draining the system, reducing downtime on service calls. Key construction details include a brass body and flange, a bottom-loaded blowout-proof stem, a Buna-N stem O-ring seal, and a virgin PTFE seat for reliable shutoff. A lever handle provides quick quarter-turn operation, and a T-handle is optionally included. This fitting is installed by licensed plumbers and HVAC technicians servicing hydronic systems.

The WATTS 68097 is intended for residential and light commercial hydronic heating applications where circulator pump isolation is required. The sweat (solder) end connection suits copper pipe installations at 1-1/4 inch nominal size. Typical installations include baseboard hot water heating systems, radiant floor heating loops, and similar closed-loop hydronic circuits where routine circulator service must be performed without full system shutdown.

Key Features

• Brass body and flange construction for durability in hydronic service
• Solder (sweat) end connection for 1-1/4 inch copper pipe
• Virgin PTFE seat provides reliable, low-friction shutoff
• Buna-N stem O-ring seal resists system fluid degradation
• Bottom-loaded blowout-proof stem for added safety
• Lever handle with optional T-handle included for flexible operation

Compatibility

Designed as an OEM-style isolation flange for 1-1/4 inch sweat-connection circulator pumps in residential and light commercial hydronic heating systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut down the hydronic system and relieve system pressure before beginning work. Solder connections require proper flux, solder, and torch technique per local plumbing codes; ensure the valve body is protected from excessive heat during soldering. Confirm the lever handle is in the closed position before removing the circulator pump.
