Teflon is a plastic material that resists high temperatures and has self-lubricating properties. This material is therefore very suitable for pistons. These piston pin retainer buttons replace the original parts which always break off and can cause serious damage to the engine if they break.
All piston pin plugs are only suitable for pistons with a 22 mm piston pin, the inside diameter of which must be measured. The diameter of the plug or button shown is the narrowest part that goes into the piston pin, the inner diameter of the piston pin must be close.
In the related parts tab, the cylinder and piston assemblies are listed where they fit without the need to measure them.
