This is the fiche-listed Royal Enfield 575595/A Washer_Seal (Rocker Cover) used on the 648 cc twin engine. Dealer/parts portals show this exact number under the cylinder head / cam cover group for the Interceptor 650 and Continental GT 650, and newer listings also map it to Super Meteor 650 and Shotgun 650 (same 648 twin), so we can confidently publish only these four to avoid returns. Its the small sealing washer that sits under the rocker/cam-cover screw. Its job is to seal light oil mist and stop the screw from marking the alloy cover. When you open the cam cover for valve-clearance service, these little seals are what usually start weeping later if you reuse old, flattened ones thats why RE sells them separately. Supplied per piece, OE size, OE material, so it clamps and seals exactly like the original.

Correct inner/outer diameter to suit 650-twin rocker-cover screws.
Prevents oil-mist / sweat around cam-cover bolts.
