Earl's Performance Multi Purpose Grommet

Earl's Performance Seals-It Multi Purpose Grommets: Race-Proven Firewall Protection

When it comes to keeping fumes, debris, and heat out of your engine bay and cabin, few solutions match the engineering precision of Earl's Performance Seals-It firewall grommets. These aren't generic rubber plugs — they're purpose-built multi purpose grommets developed by a brand with deep roots in motorsport plumbing innovation dating back to 1955.

Earl's Performance was founded by Earl Fouts in Lawndale, California, with a mission to bring military aircraft-grade plumbing technology to the racing industry. That aerospace pedigree translates directly into the Seals-It grommet line: every seal is engineered to the same exacting standards that have made Earl's the preferred plumbing choice for top funny car, sprint car, and Indy car teams around the world.

What Makes the Seals-It Grommet Different?

The core innovation behind Earl's Seals-It firewall grommets lies in their dual-action design. The seal stretches to allow a hose or AN fitting to pass through, then grips the hose firmly to prevent fumes or debris from migrating through the firewall — eliminating the traditional second hose assembly that older grommet designs required. This means a cleaner, safer, more professional installation with fewer parts and potential leak points.

Construction quality is central to what Earl's brings to this category. Each Seals-It grommet is made from fire-retardant rubber bonded to an anodized aluminum bezel, giving it both thermal resistance and structural rigidity in the demanding under-hood environment. The ultra-thin yet rugged profile ensures a flush, factory-quality appearance without sacrificing durability.

Available Configurations

Earl's offers Seals-It grommets in multiple configurations to match different plumbing setups:

• Blank (No-Hole) Version (29G001ERL): A universal "blank" grommet with a 3-inch OD mount and no pre-cut hole, allowing builders to punch or drill the exact opening needed for their specific hose or fitting size.
• -8 AN Version (29G008ERL): Pre-sized for -8 AN hose and fittings with a 0.5-inch hole and the same 3-inch OD mount, ideal for builders running standard AN-8 fuel, oil, or coolant lines through the firewall.

Both versions share the same fire-retardant rubber-over-anodized-aluminum construction, ensuring consistent quality regardless of which configuration your build requires.

Why Choose Earl's for Your Firewall Grommet Needs?

Earl's invented much of what the performance plumbing industry takes for granted today — including the patented Swivel-Seal self-indexing hose end in 1973 and the introduction of flexible PTFE-lined stainless-steel hoses to racing in the 1960s. That culture of engineering-first design is evident even in a seemingly straightforward component like a firewall grommet. When you install an Earl's Seals-It grommet, you're getting a product designed to integrate cleanly with AN plumbing systems, resist the heat and vibration of performance applications, and provide a long-term seal that holds up race after race.

Whether you're building a dedicated track car, upgrading a street/strip machine, or completing a custom hot rod, Earl's Performance multi purpose grommets deliver the fit, finish, and fire resistance that serious builders demand.
