Description
Overview:
The Reversible Nylon Piston Stop 10mm & 14mm is a genuine part used to safely lock the piston in place during engine servicing. Made from durable, non-marring nylon, it screws into the spark plug hole to immobilise the piston for jobs such as flywheel, clutch, or drive cup removal. The reversible design provides two common spark plug thread sizes in one tool: M10 and M14, covering a wide range of small engines. Suitable for both 2-stroke and 4-stroke applications, it is ideal for garden machinery and light construction equipment, including chainsaws, brushcutters, cut-off saws, hedge trimmers, lawnmowers, generators, and water pumps. Its compact form and straightforward operation make it a dependable workshop and site tool for tradespeople and DIY users alike.
