Corrosion Block Liquid in this case of 4 supplies 4 separate 4-liter refill containers, identified by SKU 76730 and listed case code 20004CASE. A case of four 4-liter refill containers for an organized replenishment program using suitable labeled dispensing equipment. Select the package by the work you plan to do and the way you want to dispense the product, while keeping the exact formula instructions with the maintenance supplies.
Corrosion Block is a corrosion-inhibiting fluid designed to penetrate affected areas, displace moisture and leave a protective film. Manufacturer literature describes spray, brush and wipe application for appropriate surfaces. That makes the delivery format an important purchase choice: a pump, aerosol and refill container offer different ways to supply the same maintenance task without establishing that every surface or electrical assembly should be coated.
This refill case contains four separate 4-liter containers, giving 16 liters total by calculation. Keep the case quantity separate from the per-container size when planning replenishment. Use compatible, clearly labeled dispensing equipment and retain the product identification after any transfer. An additional spray head or empty applicator is not assumed to be included in the refill purchase.
Manufacturer guidance identifies metal protection and electrical-component applications. Confirm the exact equipment, materials and application location; isolate electrical power before servicing and follow the equipment procedure. Inspect the treated component as part of regular maintenance and plan further care from its condition and exposure. Compare like-for-like formula and package choices before judging the size of the supply.
