Bell & Gossett 101241LF - Isolation Flange Set, 1-1/2"

Designed to provide a secure, leak‑free isolation point in hydronic and HVAC piping systems, this flange set simplifies maintenance and minimizes downtime. The 101241LF isolation flange set from Bell & Gossett features two 1.5" flanges engineered for precise alignment and fast installation.

The set uses a dual‑flange configuration that seals around pipe ends with bolted gaskets, allowing sections of a loop to be isolated without cutting or depressurizing the entire system. When installed, pressure is maintained on the active side while the isolated side can be serviced safely.

Key System Performance Baselines:

• Leak Prevention: Precision‑machined mating surfaces create a zero‑leak seal under normal operating pressures.
• Installation Speed: Pre‑drilled bolt holes and standardized 1.5" sizing cut fit‑up time in half.
• Durability: Cast‑iron construction resists corrosion and wear for long‑term reliability.
• Compatibility: Fits standard 1.5" NPT‑type connections across most HVAC and hydronic equipment.
• Pressure Rating: Rated for up to 150 psi, suitable for most commercial loop applications.

⚠️ Application Profile: Ideal for boiler loop isolation, chill‑water pump maintenance, air‑handling unit service, district‑energy system sections, and any scenario requiring quick pipe isolation without system shutdown.
