Took apart my transom shower to fix a leak. There are red fiber washers where the steel shower control valve lines connect with the red and blue water supply lines. Ha anyone found a source for these washers other than the Beneteau parts site? There they are 14 cents each and $10.00 for shipping! Beneteau's part #'s are 535100 and 535300. The one in the pic is (theoretically since it has shrunk) 17mm OD x 12 mm ID. No luck at my local Ace Hardware and Amazon has some but are in a box of various sizes and it is hard to tell what you're really getting.
