Description
Overview:
This Genuine Honda Exhaust Gasket (OEM No. 18381-ZL8-305) is a heat‐resistant sealing gasket used at the exhaust port to create a gas‐tight joint between the cylinder head and the muffler or exhaust pipe. Built for small Honda petrol engines commonly found on lawnmowers, pressure washers and other light construction and garden equipment, it helps prevent exhaust leaks that can reduce performance and increase noise. Designed for dependable fit and function on engines such as the Honda GC160 and GCV160, it supports smooth running, proper backpressure, and efficient operation. Made from durable gasket materials suited to high temperatures and vibration, it is a straightforward, reliable replacement during routine maintenance or when refitting an exhaust.
Key Features:
- Genuine Honda OEM part for assured compatibility and quality
- OEM number 18381-ZL8-305 for easy identification and parts matching
- Heat‐resistant construction to withstand continuous exhaust temperatures and repeated heat cycles
- Precise port shape and bolt spacing for a secure, leak‐free seal
- Helps maintain engine power, fuel economy and emission performance by preventing exhaust leaks
- Reduces exhaust noise and fumes escaping at the manifold/muffler joint
- Robust against vibration and compression set for long service life
- Suitable for routine exhaust or muffler replacement, head work, and general servicing
- Compatible with a wide range of Honda GC/GCV/GS/GSV series engines used in garden and light construction machinery
- Genuine Part status ensures consistent material quality and fit
Typical Applications:
Used when replacing or refitting mufflers on Honda-powered lawnmowers, pressure washers, water pumps, compactors and general-purpose equipment. Ideal during exhaust system maintenance, cylinder head servicing, or any repair where the exhaust joint is disturbed, to restore a proper seal and prevent leaks.
