Bell & Gossett 101226LF - Isolation Flange Set, 3/4" Sweat

A compact isolation flange designed for 3/4" sweat pipe connections allows sections of a hydronic system to be isolated quickly for maintenance or repair. The Bell & Gossett 101226LF isolation flange set features a durable cast‑iron body and a precision‑machined 3/4" sweat union.

When installed, the flange creates a sealed barrier between pipe segments, enabling water flow to be stopped on one side while the other remains pressurized, which eliminates the need to drain the entire system for service.

Key System Performance Baselines:

• Leak Prevention: Provides a tight seal that resists water leakage under normal operating pressures.
• Rapid Isolation: Allows sections to be isolated within seconds, minimizing downtime.
• Durable Construction: Cast‑iron body withstands high temperatures and corrosion.
• Standard Compatibility: 3/4" sweat threads match common HVAC and boiler piping.

⚠️ Application Profile: Ideal for boiler shut‑off points, pump bypass loops, heat exchanger service sections, and retrofits in commercial HVAC and hydronic heating systems.
