27mm GY6 125-232cc Exhaust Gasket - 27x3.5mm

27mm Exhaust Gasket for GY6 125cc-232cc Engines

This exhaust gasket suits GY6 engines in the 125cc to 232cc range. It creates a tight seal between the exhaust header and the cylinder head, which helps the engine keep its performance. If you are servicing your scooter, this is one of the GY6 150cc scooter parts worth swapping out on a regular schedule to stop exhaust leaks before they start.

Construction and Fitment

The gasket is built from a metal and fiber composite. During installation it settles into place to form a snug seal at the joint. Its slotted design accepts exhaust flanges with 45–51 mm bolt spacing, so it can work with a range of exhaust setups.

When to Replace

This gasket is meant for one use, so install a new one every time you take the exhaust header off. Swapping it regularly keeps the engine running efficiently and helps prevent leaks. During any scooter maintenance, take a moment to inspect the gasket's condition and measurements.
