This Cylinder & Exhaust Muffler Gaskets Kit is a genuine Stihl replacement for the TS400 disc cutter. It includes the cylinder base joint gasket and the exhaust muffler gasket, made from durable, heat‐resistant materials to provide a reliable seal in high‐temperature engine areas. The gaskets maintain correct compression at the cylinder base and seal the exhaust to the cylinder, helping to prevent loss of power, hot gas leaks, and carbon build‐up at the port. Designed to the correct OEM profile for a precise fit, this kit supports smooth running, easier starting, and consistent cutting performance in demanding site conditions. Supplied as a direct replacement for OEM No. 400 424, it is suitable for routine maintenance or top‐end service on the Stihl TS400.

Key Features:
– Genuine Stihl part for assured fit, material quality, and longevity
– Includes both critical seals: cylinder base joint gasket and exhaust muffler gasket
– Restores proper compression and exhaust sealing to maintain engine performance
– Heat‐resistant construction suited to high‐load, high‐temperature operation
– Cut to OEM dimensions for a clean, accurate fit with original fixings
– Helps prevent hot gas, oil mist, and soot leaks around the exhaust outlet
– Reduces risk of blow‐by that can cause power loss and excess noise
– Supports easier starts and stable idle after overhaul or muffler service
– Simple to fit during routine servicing to minimise downtime
– Direct replacement for OEM 400 424

Typical Applications:
Used during TS400 maintenance, exhaust removal, or top‐end rebuilds to renew critical engine seals. Ideal when replacing a muffler, addressing exhaust leaks, restoring compression after wear, or reassembling the cylinder following piston, ring, or de‐coke work. Helps keep the cut‐off saw running reliably on concrete, masonry, and asphalt jobs.
