This rubber seal fits around the dash ventilation aperture in the bulkhead, forming an airtight barrier between the engine bay and cabin on non-air-conditioned Defender and Series 3 vehicles. Its function is to prevent engine bay fumes, heat, and water ingress from entering the interior through the bulkhead ventilation opening. Deterioration of this seal typically presents as draughts, water leaks onto the footwell area, or exhaust smell entering the cabin. Key Features Manufactured in plain rubber, matching the original non-air-conditioned bulkhead specification Fits directly to the dash ventilation aperture in the bulkhead without modification Correct OEM-equivalent specification for vehicles up to chassis number HA704901 Inspect the surrounding bulkhead panel for corrosion before fitting, as rust around the aperture can prevent a proper seal Vehicle Fitment Fits Land Rover Defender (1986–2006) without air conditioning up to chassis number HA704901, and Land Rover Series 3 with the plain rubber type bulkhead configuration.
