MAGNASEAL is a unique patented magnetic urethane sheet that is the safest, most effective and efficient way to stop or prevent leaks of hazardous materials.

Utilizing MAGNASEAL will help you to:

Improve Safety –
Responders can apply the MAGNASEAL Leak Patch with minimal exposure to chemical products.

Reduce Costs –
MAGNASEAL products are a fraction of the cost compared to the cost of a spill – cost of cleanup, loss of product, downtime, fines, and litigation.

Increase Effectiveness –
The MAGNASEAL Leak Patch is designed to be flexible and conform to the shape of the breached vessel.

Reduce Time –
First Responders can apply the MAGNASEAL Leak patch immediately, staunching the flow until the Hazardous Materials Response Team arrives.

Increase Efficiency –
The MAGNASEAL Leak Patch is a single person application and far more effective than traditional methods such as wooden pegs & putty, ratcheting bladder systems, and other cumbersome and complicated magnetic devices.

Help The Environment –
MAGNASEAL products help Responders minimize soil and water contamination affecting human, animal, and marine life.



The MAGNASEAL Drain Cover is a flexible, ultra thin cover that comes in low strength magnetic as well as non-magnetic. It is superior as a drain cover because of the urethane’s tendency to want to stay flat even if it has been rolled or crumpled for an extended period of time. This makes the drain coverage complete without air gaps and without the need to apply weight to hold it down.

The magnetic drain cover offers even more security so it will stay in place during high liquid flow. It has the same high chemical resistance which can allow it to be used in various situations. Unlike other similar products, the drain cover will not crack, dry out, or become hard over time, exposure to air, heat, and sun.

Available as:

8” x 8” – Magnetic
8” x 8” – Non-Magnetic
12” x 12” – Magnetic
12” x 12” – Non-Magnetic
18” x 18” – Magnetic
18” x 18” – Non-Magnetic
24” x 24” – Magnetic
24” x 24” – Non-Magnetic



The MAGNASEAL Leak Patch is a high strength, magnetic, flexible urethane patch. It can hold back up to 30 pounds of pressure. All sizes come with 4 built in “D” rings and 2 6 inch continuous loop webbing straps which can be used for application.

All Leak patches are 5/8 inch thickness. The corner D Ring adds 1/4 inch to the thickness.

The 18 inch Leak Patch with valve comes fitted with a threaded 2 inch pass through valve which will allow for off loading. This passthrough valve adds 1 1/2 inches to the thickness of this patch.

Carrying Case – Each MAGNASEAL Leak Patch comes with a carrying case. The carrying case has an industrial zipper and insulated sides to buffer the strength of the MAGNASEAL while it is not in use. The carrying case makes it easy to keep MAGNASEAL protected from UV light and out of the way.

Available as:

8” x 8”
12” x 12”
18” x 18”
24” x 24”


MAGNASEAL Sewer Covers
