Primary level plug and copper washer for 1959-67 Triumph unit 350 & 500 twins and 1963-67 Triumph unit 650 twins. Plug is the correct 1/4″-26 CEI thread ds57 domed bolt. While early unit twins called for WE170 fiber washer, later twins used E2441 (70-2441) copper washers which are an improvement over the fiber washers and are a direct replacement.

***Note- 1968 parts books called for these as well, but we’ve seen original 1968 models fitted with both 1/4″-26 plugs and the 1/4″-20 plugs fitted to 1969 and later Triumph twins. If you have a 1968 model year, we recommend verifying threads prior to ordering.
