Description
Overview:
The Gasket for Stihl 090 and 090G (OEM 6503 129 2500) is a genuine Stihl sealing component used between mating engine parts to prevent air, fuel and oil leaks. Made from a durable, heat- and fuel‐resistant composite gasket material, it maintains a tight, consistent seal under vibration and operating temperature. This improves reliability, compression integrity and mixture control in two‐stroke machinery. Designed for heavy‐duty Stihl chainsaws and cut‐off saws, it suits servicing tasks where the original seal has aged, split or been disturbed during disassembly. Precision manufacturing ensures the correct bolt pattern and port alignment for an accurate fit on applicable machines, including the Stihl 090 and 090G. Using a genuine Stihl gasket helps preserve performance and protects engine components from avoidable wear.
Key Features:
- Genuine Stihl part for assured compatibility and quality
- OEM reference 6503 129 2500 for accurate identification
- Fuel, oil and heat resistant composite for long service life
- Precision cut for proper port alignment and fastener fit
- Helps restore compression and prevent air leaks and lean running
- Stable sealing under vibration typical of two‐stroke engines
- Clean edges and consistent thickness for straightforward fitting
- Supports reliable starts, smooth idling and correct carburetion
- Suitable for maintenance, rebuilds and leak rectification
Typical Applications:
Used during engine rebuilds, top‐end services, or when splitting and reassembling casings and manifolds on Stihl chainsaws and cut‐off saws. Ideal when addressing hard‐starting, erratic idle, or visible oil/fuel seepage. Replaces aged or damaged gaskets to re‐establish a tight seal and protect against air ingress that can lead to poor performance or engine damage.
Also known as:
Seal, jointing gasket, base gasket, flange gasket, packing, spacer gasket, engine gasket, manifold gasket. Commonly referred to as a sealing interface between cylinder, crankcase, or adapter faces in two‐stroke machinery.
