The cylinder head valve screw plug is a critical component used to seal and secure the valve assembly within the cylinder head. With a length of one inch and a M22 x 1.5 mm thread, it provides a tight, leak-proof fit essential for maintaining combustion chamber integrity. The flat end width of 0.75 inches ensures proper seating, preventing fluid or gas escape under high pressure. Made from durable steel, this plug withstands the thermal stresses and mechanical forces experienced during engine operation. Its precise dimensions and robust construction contribute to maintaining optimal valve function, which directly impacts engine efficiency and emissions compliance. Proper installation prevents leaks that could lead to performance issues or damage. This part’s importance is recognized by maintenance professionals who rely on quality components.
