The Mifab MI-GARD-3 Trap Seal is a 3-inch floor drain trap protection device designed to block sewer gases, odors, and pests while allowing unrestricted water flow. Made from durable, chemical-resistant materials, it fits securely into standard 3-inch floor drain bodies and works without relying on water to maintain a seal—ideal for floor drains in infrequently used or dry areas. Its low-maintenance, mechanical design makes it a reliable choice for commercial, industrial, and institutional settings focused on maintaining hygiene and code compliance.
