Valve Plug 6.964-030.0

This cylinder head plug, also referred to as an outer valve plug, is a genuine OEM replacement part used in pressure washers. It is a plastic cap with one O-ring and locking tabs around the body for added security. It is used to seal the cylinder head to maintain the correct pressure levels, and to prevent water from escaping. Over time it is common for the plug to become brittle and break, or the locking tabs may wear down. If the plug is faulty it will need to be replaced to avoid leaking and uncontrolled spraying during operation. To remove the plug, twist it until the locking tabs disengage and pull it out. You may need to use a pair of pliers or a wrench to pry the plug out if there is a buildup of debris around the mounting hole. Each plug is sold individually.
