Nu-Calgon 4774-0 Coil Gun Sprayer - 2 Qt, Quick-Connect, 5 Dilution Ratios, Foam Wand

All-in-one coil care with flexible dilution

The Nu-Calgon 4774-0 coil gun sprayer packs essential spray features into a compact, portable 2-quart bottle. The foam wand adds tactile cleaning action, and the deflector tip fans the spray for even distribution across coils, racks, and surfaces.

Five dilution settings give you options from light cleaning to stronger formulations. The ratios are 3:1, 4:1, 6:1, 9:1 and 10:1, letting you preserve chemical concentration while achieving the coverage you need. In practice, a lighter ratio suits delicate surfaces, while richer mixes target tougher residues. Having adjustable dilutions supports varied workflows without swapping tools, so you can adapt on the fly when tackling different surfaces or equipment.
