Product Description
Ensure optimal fuel-air mixture and prevent engine idling issues with the HTA Seal-Joint Carburettor Flange Rubber. Specifically designed for Royal Enfield 350cc BS4 models, this aftermarket component serves as the critical flexible link between the carburettor and the engine’s intake manifold.
Engineered by HTA (a recognized name in aftermarket rubber components), this flange rubber is built to replace the OEM part (Reference No: 576618/B). In BS4 UCE engines, the carburettor is subject to high-frequency vibrations and intense engine heat, which can cause standard rubber to crack, leading to “lean runs” or erratic idling. The HTA seal-joint is manufactured from a fuel-resistant rubber compound with a reinforced internal structure to ensure an airtight seal. Replacing a weathered flange with this HTA unit helps restore factory-level throttle response and prevents the “hunting” idle common in bikes with intake leaks.
Key Features:
-
HTA Precision Build: A high-quality non-genuine alternative that matches the mounting dimensions of the original BS4 carburettor setup.
-
Vibration Dampening: The flexible rubber construction absorbs engine pulses, preventing the carburettor from shaking loose or foaming the fuel in the bowl.
-
Airtight Sealing: Provides a leak-proof connection to maintain the vacuum integrity required for precise BS4 emission-compliant tuning.
-
Petrol & Heat Resistant: Formulated to resist the corrosive effects of modern ethanol-blended fuels (E20 compatible) and high cylinder head temperatures.
-
Cost-Effective Maintenance: Offers a budget-friendly solution for restoring engine performance without the high cost of OEM-branded rubber kits.
