COOL-FIT 4.0 Barrel nipple with insulation

  Datasheet (PDF)

The Georg Fischer COOL-FIT 4.0 barrel nipple with insulation provides a factory pre-insulated, vapor-tight jointing solution engineered specifically for creating direct, ultra-compact spigot connections between adjacent COOL-FIT 4.0 Type A electrofusion fittings. Featuring an advanced 3-in-1 construction that permanently bonds a high-density PE100 core carrier pipe, high-efficiency halogen-free GF HE closed-cell foam insulation, and an impact-resistant black protective outer jacket, the component ensures unbroken thermal shielding across the entire piping envelope. Engineered for demanding industrial cooling installations, secondary glycol circuits, process refrigeration in food and beverage facilities, cold storage systems, and commercial HVAC chilled water distribution networks, the assembly operates reliably within a medium temperature spectrum from -50 degrees Celsius to +60 degrees Celsius. The factory-prepared, calibrated PE100 spigot ends facilitate rapid, clean, and secure jointing using standard electrofusion couplers, entirely eliminating tedious manual stripping, secondary field foaming, or external adhesive wrapping while ensuring moisture-proof and vapor-tight integrity. By preventing thermal energy dissipation, surface condensation, and structural ice accumulation at critical pipe junctures, the fitting prevents underlying metallic degradation, lowers cooling machinery operational loads, and minimizes long-term maintenance over a twenty-five-year service lifespan. The lightweight thermoplastic design simplifies alignment in restricted mechanical spaces, technical risers, and overhead service racks, delivering streamlined flow passages and dependable system efficiency across critical refrigeration infrastructure.
