A reliable isolation flange provides a quick, leak‑free method to shut off a section of pipe for servicing or repair without disturbing the rest of the system. The **101228LF** set from Bell & Gossett is designed for 1‑1/4" sweat connections and offers durable, easy‑to‑install sealing.

The flange incorporates a precision‑machined sealing surface that mates directly with the pipe's sweat joint, allowing pressure‑tight isolation while maintaining full flow when the valve is open. Its carbon‑steel construction and protective coating resist corrosion, extending service life.

Key System Performance Baselines:

  • Seam Integrity: Maintains pressure ratings up to 150 psi for reliable isolation.
  • Corrosion Resistance: Carbon‑steel body with protective coating ensures long‑term durability.
  • Installation Speed: Thread‑less sweat joint reduces labor time and simplifies field work.

⚠️ Application Profile: Ideal for HVAC heating loops, chilled‑water systems, boiler feed lines, and any hydronic circuit requiring quick isolation during maintenance or repair.
