Firewall Grommet -6an

The Firewall Grommet -6AN from SEALS-IT is a precision-engineered seal designed to protect and organize hydraulic and pneumatic lines passing through engine firewalls and bulkheads. This single-hole grommet prevents fluid leakage, reduces vibration-induced wear, and maintains a professional appearance in high-performance and industrial applications. Whether you're building a custom vehicle, installing an aftermarket fuel system, or managing multiple hose runs in a confined space, this grommet isolates hoses from sharp edges and extreme temperatures while maintaining system integrity.

Constructed from a durable aluminum and rubber composite, the Firewall Grommet -6AN features a 3-inch outer diameter with a 0.375-inch inner diameter bore sized for -6AN hose and fittings. The 0.12-inch wall thickness provides robust support without adding excessive bulk, while the black aluminum exterior and natural rubber interior create a weather-resistant seal that dampens vibration and thermal stress. The combination of materials ensures excellent chemical resistance, temperature stability, and long-term durability in engine bays and exposed installations where standard plastic grommets would fail.

This grommet is ideal for custom fuel systems, turbo installations, intercooler plumbing, and any -6AN hose application requiring a firewall or bulkhead penetration. It's compatible with all standard -6AN hose and AN-6 fittings, making it a direct fit for motorsports builds, vintage restorations, and professional fabrication shops. Installation is straightforward—simply press the grommet into your pre-drilled hole and route hose through the center bore. Its compact footprint (3.3 x 0.3 x 4 inches) and lightweight design (0.03 lbs) make it suitable for tight engine compartments and weight-sensitive applications.
