When you’re looking for an expertly engineered protective urethane cover against accidental spills for drains, grates, and manholes, look no further than the Original DrainProtector™ from PSI Urethanes

It’s tackiness, chemical resistance, ease of use, and availability continue to set it apart from similar protective covers.

Original Drain Protector™ Features


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
  • 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 it 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!
