Product TypeIsolation Flange Set

The 3/4" NPT isolation flange set provides a secure, leak‑proof point for shutting off flow during maintenance or repair of hydronic equipment. Featuring the **101221LF** part number, this Bell & Gossett solution simplifies isolation without removing pipe sections.

Designed with a dual‑flange construction, the set bolts onto existing pipework, creating a sealed barrier that isolates sections while maintaining system integrity. The NPT threads ensure a tight, pressure‑rated connection, and the compact design fits tight spaces common in boiler and chiller loops.

Key System Performance Baselines:

  • Leak Prevention: Precision‑machined faces minimize seepage under high pressure.
  • Fast Installation: Standard 3/4" NPT threads reduce labor time.
  • Thermal Compatibility: Materials selected for consistent performance across temperature ranges.
  • Durable Construction: Corrosion‑resistant alloy end caps extend service life.

⚠️ Application Profile: Ideal for boiler shut‑off points, chilled‑water plant maintenance, boiler feed‑water loops, and any hydronic system requiring quick, reliable isolation.
