This 168 valve guide is a core matching part for single-cylinder small gasoline engines. Precisely cast from high-hardness alloy cast iron with uniform density, it boasts outstanding wear and heat resistance, resisting cracking and elongation during long high-temperature engine operation. The finely honed smooth inner bore cuts friction during valve reciprocating movement and reduces valve stem abrasion to extend the whole machine’s service life. Standard outer and inner diameter perfectly match the cylinder head mounting holes of 168 engines, requiring no grinding or reaming during maintenance replacement and supporting direct press fitting. It fits 168-series gasoline generators, agricultural tillers, water pumps and other power equipment. Superior to ordinary cast iron guides in wear resistance, it lowers repeated disassembly and repair costs, suitable for bulk stocking in repair shops and farmer equipment maintenance.
