Drain Cover Seals

Drain cover seals go down fast so liquids can't pass.

When a spill strikes, it’s a good move to seal off your floor or storm drains entirely, so no unwanted liquids get into the water supply. If you need to comply with EPA's SPCC and Stormwater regs, PIG DrainBlocker Drain Covers are a must-have. They feature a super-sealing, tacky urethane bottom layer that forms a complete seal around your drain – unlike a magnetic drain cover, which can’t form an impenetrable seal. And when you need to access your drain again, they pull off easily (and can be reused over and over again).

Accessories for Drain Cover Seals


Our original PIG DrainBlockers with Dupont Elvaloy are great for spill response or washdown applications – but sometimes you need something a little more rugged. Our Drive-Over Drain Cover is so tough, it can withstand constant runovers from 18-wheelers – and never shred. If you don’t need all the bells and whistles of a DrainBlocker that’s designed for repeated use, long-term deployment or vehicle traffic, our Rapid Response DrainBlocker is perfect. For limited-use situations, this emergency drain cover still protects your drains and helps you comply with SPCC regs – but it’s designed to just cover the basics. (Mount them on the wall or stash them in spill kits throughout your facility!)
