These drain plugs are stationed at every floor drain in our chemical storage area. During a forklift incident that ruptured a tote, our team sealed all four drains in under a minute. Zero discharge to the sewer system. Our EHS director was thrilled.

Expert Insights
The 4-inch diameter is a widely used floor drain size in industrial and automotive service environments, making this plug a critical component of any spill prevention kit. At 3 lbs, this plug is slightly heavier than the 2-inch and 3-inch models, providing added stability and seal integrity once placed in the drain. Polyurethane construction ensures long-term durability and resistance to degradation from repeated contact with petroleum-based products and chemical solvents. For comprehensive drain coverage, combine this with smaller yellow plugs or consider the Yellow Drain Plug Set which bundles the 4-inch, 3-inch, and 2-inch sizes at a discounted price.

Why Floor Drain Plugs Are Essential
Indoor floor drains connected to the sanitary sewer or storm system are a primary pathway for spilled chemicals and petroleum to leave a facility. SPCC plans and OSHA spill response procedures require the ability to seal floor drains during spill events to prevent pollutant discharge. Floor drain plugs deliver instant, tool-free drain sealing that meets regulatory requirements for indoor spill containment.

What Our Customers Say
Real reviews from the facilities, field crews, and agencies that count on us.
-
-
The removable eyebolt makes retrieval easy after a spill event. We tested every size during our annual spill drill and they all sealed perfectly. The polyurethane is tough — we've reused the same plugs dozens of times without any degradation.
-
Simple product that does exactly what it claims. We used to stuff rags into drains during spill events — this is infinitely better. Instant seal, easy retrieval, and our SPCC inspector specifically approved them as compliant drain sealing devices.
