S&S Socket head plug, 1/4″ NPT For Harley-Davidson
Socket head plugs for blocking of oil or vent holes when changing the lubrication or venting system. For example when changing from chain to belt primary on a pre 1984 Big Twin, you must block the front chain oiling system. This can be done by removing the fitting and installing the 1/16″ NPT plug. 1/4″ NPT and 1/8″ NPT plugs are used to block vent holes on crankcases etc.
