Nu-Calgon 4296-51 Pan-Spray™ Leak Sealer - Black Color - 16 Ounce Aerosol

The Nu-Calgon 4296-51 Pan-Spray™ is a professional-grade rubberized leak sealer and patch specifically engineered for the HVACR and plumbing industries. This aerosol spray provides an immediate, waterproof solution for sealing leaks in condensate pans, cooling towers, and drainage systems, preventing costly water damage and extending the life of existing equipment.

Technical Performance:

Formulated to withstand extreme environments, this sealer creates a durable, flexible rubberized coating that will not chip, flake, or peel over time. It maintains its integrity across a wide temperature range of -10°F to 250°F, ensuring the seal remains effective in both freezing evaporator conditions and high-heat mechanical rooms. The fast-acting formula dries to the touch in just 20 to 30 minutes, allowing technicians to complete repairs quickly during a single service call.

Key Features and Function:

  • Instant Waterproof Barrier: Provides a permanent, flexible seal that stops leaks in metal, plastic, and masonry surfaces.
  • Corrosion & Rust Protection: Coats metal surfaces to block out moisture and oxygen, preventing further oxidation and rust.
  • High-Build Flexibility: The rubberized formula expands and contracts with thermal changes, preventing cracks from reopening.
  • Multi-Surface Adhesion: Superior bonding capabilities on galvanized steel, aluminum, PVC, and concrete.

Product Details and Key Specifications:

  • Part Number: 4296-51

  • Color: Black
  • Container Size: 16 Ounce Aerosol
  • Coverage: Approx. 20 sq. ft. per can (depending on thickness)

🛠️ HVAC Depot Pro Tip: The Tip-Clear Technique

To ensure the spray nozzle doesn't clog for future use, always invert the can and spray for 2 seconds after your repair is finished until only clear gas comes out. For deep cracks in rusty condensate pans, wire-brush the area first and apply a light initial "tack coat" followed by a heavier second coat 5 minutes later for maximum thickness and durability.

Cross-Reference & Compatibility:

The 4296-51 is a direct professional alternative for the following applications:

  • OEM Numbers: 4296-51, 429651
  • Industry Standards: Used in place of traditional asphalt-based sealers.
  • Related Products: 4296-50 (White Pan-Spray version).

Extensive Model Compatibility List:

  • HVAC Equipment: Condensate Drain Pans, Evaporative Coolers, Swamp Coolers, Humidifier Reservoirs.
  • Roofing & Drainage: Gutters, Downspouts, Flashings, Roof Vents.
  • Commercial: Cooling Tower Basin Repair, Fluid Cooler Sealing.
  • Plumbing: Waste piping exteriors and concrete sumps.
