Split Grommet Seal - No Hole

The Split Grommet Seal - No Hole by SEALS-IT is a specialized firewall grommet engineered for applications requiring a sealed cable or wire passage without a pre-drilled opening. Designed for custom installations in vehicles, industrial equipment, and tactical systems, this blank split grommet allows builders and technicians to create custom hole sizes while maintaining a professional, weathertight seal. The no-hole design makes it ideal for situations where standard pre-sized grommets don't match exact routing requirements.

Manufactured with a dual-material construction featuring aluminum and natural rubber, the Split Grommet Seal combines structural integrity with superior sealing performance. The 4.5-inch outer diameter accommodates larger firewall openings and cable bundles, while the 0.125-inch thickness provides optimal flexibility and compression set resistance. The flat profile and split design allow for tool-free installation around existing wiring or hoses without disassembly, reducing installation time and potential damage to sensitive components. The black finish on the aluminum ring resists corrosion and UV degradation, while the natural rubber sealing surface remains pliant across temperature extremes.

This grommet is essential for automotive restoration, custom wiring harness installations, and tactical vehicle builds where off-the-shelf solutions fall short. Professionals and DIY builders benefit from the ability to drill custom hole sizes to match exact cable diameters—eliminating water intrusion, dust ingress, and electromagnetic interference. The split construction accommodates retrofit applications where complete firewall removal isn't feasible, making it indispensable for field repairs and system upgrades in demanding environments.
