A tacky, adhesive surface creates a positive seal that stops chemical spills every time. A positive seal prevents even the smallest amount of contaminant/liquid from getting past. Positive seals do not allow any external or internal leakage, whereas non-positive seals allow a small amount of internal leakage. When dealing with hazardous materials or toxic chemicals, a positive seal is a must-have.

Chemically Resistant

The polyurethane DrainProtector™ is compatible for use with a wider range of chemicals and substances than rubbers and plastics. It’s often more suitable when coming into contact with certain solvents, oils, and chemicals. Plus, it’s environmentally safe!

The DrainProtector™ safety seal has a chemical compatibility rating of “Good” with the following chemicals: Acetone, Chlorine Standard Solution (1000ppm), Ethanol (95%), Hydraulic Fluid, Hydrochloric Acid (18.5%), Hydrogen Peroxide (30%), Isopropyl Alcohol, Mineral Oil, Chlorine Bleach (5% Sodium Hypochlorite), Sodium Hydroxide (40%), Sulfuric Acid (50%), Xylene, Gasoline, Antifreeze, and Diesel Fuel.

Easy-to-Use & Store

A unique engineering process allows the DrainProtector™ to be heavy enough to seal, yet light enough to be portable and easy-to-use. When it’s time for use, the DrainProtector™ is even simpler to apply at a moment’s notice. To use the DrainProtector, follow three easy steps to ensure maximum effectiveness:

  1. Make sure the DrainProtector™ Safety Seal is the correct size. For best results, use a DrainProtector™ Safety Seal that’s 6″ larger than the outside of the drain.
  2. Apply the DrainProtector™ Safety Seal. Remove debris from the drain area you’re covering. Remove the plastic film from the DrainProtector™ and save it to replace after use. Place the DrainProtector™ Safety Seal YELLOW SIDE UP over the drain, grate, or manhole you are sealing.
  3. Wash the DrainProtector™ Safety Seal before storage. Wash the safety seal in warm water with a non-abrasive detergent or petroleum solvent cleaner. Dry with a cloth and re-apply the plastic film. Roll the DrainProtector™ Safety Seal (ORANGE SIDE IN) around its original tube and place it back into the provided box.

Cost-Efficient & Reusable

After using, simply wash the urethane DrainProtector™ in warm water with a non-abrasive detergent or petroleum solvent cleaner. Dry and then replace its plastic film. Roll it YELLOW SIDE UP on its tube and return the tube to the container. The DrainProtector™ is tough enough to stand up to repeated use when properly cleaned and stored!
